I noticed in knoppix version 5.1.1 it has a slow down script to read the USB device more carefully and that one works flawlessy on my Dell D820. DSL-3.4 and Knoppix version 3.6 never is able to read the knoppix image. I like Knoppix version 3.6 because it has both 2.4x and 2.6x kernels to choose from.Here is is:
# All interactively requested modules should be loaded now.
# Give USB-Storage devices some more time to register
if test -d /proc/scsi/usb-storage; then
echo -n "${CRE}${BLUE}Allowing slow USB-devices some more time to register...${NORMAL}"
ash -c "sleep 6"
echo "${BLUE}Ok.${NORMAL}"
fi
# Check for ide-scsi supported CD-Roms et al.
test -r /proc/scsi/scsi && FOUND_SCSI="yes"
I put the before and after script so you know where it is in version 5.1.1 but that is the key I believe that makes 5.1.1 work on all systems. Is it possible to adapt that script to linuxrc file for DSL-3.4?
Maybe that alone will not take care of the problem? I am going to try an older version of DSL to see if that works.
Anyone good with bash scripting let me know what I have to modify in that script in order to try it in the DSL-3.4 linuxrc bash file? Thanks

I have this as a replacement for the wait_usb function in linuxrc and will be available in 3.4.2 and the next dsl 4.I would rather not penalize everyone with this slow down "sleep 6". But instead leave it as a separate (existing) boot option of "waitusb"
If you wish, just modify the existing wait_usb function on the line
sleep 1
to
ash -c "sleep 1"
See if this works, as it loops and exits when found thus not wating to wait the full count of 6.
If not, then just repace the entire function with the
wait_usb(){
ash -c "sleep 6"
}
Since you have such hardware to test this, it will be great to get your feedback.

First off thanks very much for the reply and suggestions.I actually tried all four methods changing sleep 1 to sleep 6.
Then modifying the line sleep 1 to ash -c "sleep 1"
Then modifying it to ash -c "sleep 6"
Then finally removing or actually adding #'s to about 6 or seven lines of that wait_usb function and replacing as you said with:
wait_usb(){
ash -c "sleep 6"
}
I basically copied and pasted that. Should there be a space between the () ? Like this ( ) and also a space between () and { ?
Anyhow nothing seemed to help. The kernel boots perfectly and here is what happens:
probing for SCSI....
checking for USB....
Scanning for USB devices.....Done
Enabling DMA acceleration for hdc
Can't find Knoppix filesystem Sorry
Dropping you to a very limited shell
This also happens with Knoppix v3.6 using both 2.4x and 2.6x kernels but does not happen with Knoppix 5.1.1 usb boot so it cannot be the media or device right? It must be some tricky script the Knoppix 5.1.1 has?
Anayhow what can I pass as a cheatcode at the boot prompt:
waitusb ?
Maybe I can try different times?
My system is a Dell Latitude D820 so if you can find someone you know or if you want me to try anything else or even send me a linuxrc file to try please be my guest. Keep in mind this probably will happen to many Latitude D series like the D600 series etc.
Thanks for your help and hope this can be resolved?

Thanks for testing this. I am a little confused by your remark on the cheatcode.In order to call the wait_usb function you will need to pass the waitusb cheatcode at the initial boot prompt
boot: dsl waitusb
plus any other boot options that you normally need.
Or add waitusb to the append section of your boot loader.
Since I don't have any hardware to test this on, I could only extract out the static ash shell from minirt24.gz and run ash -c "sleep 6" and that worked fine. So, I would think, if the boot option waitusb is used, the actual sleep should occur.

Which I tried before modifying the linuxrc bash script file.at the boot prompt:
dsl waitusb
Did not help. What else could it be? If I put the initrd image file on the USB it boots fine. However once booted into X if I put another USB stick in and run fdisk -l it does not see the additional inseted usb stick and only the one DSL is on /dev/sda. No /dev/sdb shows up.
So it might be a USB driver issue maybe and not a timing issue?
Ok One final piece of information. I booted DSL using the initrd as the image file and have the dmesg below to see if that can tell you anything but as far as I can see the USB devices are seen but not sure if configured correctly? These are USB ports but I set the Bios to 1.1 compatibility.
dmesg:

Looking through this log file, I see usb hub assigned irq 10,11,9,5?Are you using a usb hub?
Do you have both front and rear usb ports on your computer?
Best to try rear ports first.
Also could be IRQ conflict.
Try looking at...
cat /proc/interrupts
Posted by emunity on Aug. 17 2007,21:46
No Hub. I will look for IRQ conflics. I can get Knoppix 5.1.1 to boot but maybe since thats kernel 26.x it may handle the interrups differently?I tried all the ports rear and side. I will try again plus I will remove the USB mouse. There are two USB ports on the side and one is where I put the USB mouse and the other dsl.
Posted by roberts on Aug. 17 2007,22:13
When you put the mod in are you seeing "Waiting for USB devices" ?If not, then try moving the ash -c "sleep 6" directly inline like this:
if test -n "$WAITUSB"; then
echo -n "${CRE}{BLUE}Waiting for USB devices${NORMAL}..."
ash -c "sleep 6"
echo "${BLUE}Done.${NORMAL}
fi
I can see the Waiting message and it does wait when I use the waitusb boot option.
Posted by emunity on Aug. 17 2007,22:21
No I don't see that message at all waiting for USB drives.I am going to try that. I never lined the script up like that. Will try it that way shortly.
Here is my cat /proc/pci readout
Do you want me to remove the entire usb_wait function and just put in that script or insert that where the sleep 1 is and line it up as you have?
Posted by emunity on Aug. 17 2007,22:44
got a /linuxrc : 101 Syntax Error: "|" unexpected.Here is some before and after script in the linuxrc file. I removed as you can from the wait_usb function all the way down to "}" then just added your script.
Please check it not sure why I got the syntax error.
Thanks

Delete the wait_usb function and replace the wait_usb function call with the echo & ash statements.I put mine inline as I have shown and can see and experience the delay.
I used the ash -c "sleep 6"
Posted by emunity on Aug. 17 2007,22:55
Can you show me here what t shoudl look like? I printed out some of the script above.I think I remmed out the wrong lines.
Is this the part I need to modify only?
# Check for user request to wait for slow USB devices
if test -n "$WAITUSB"; then
wait_usb
fi
Remove all that and replace it with your script? Also don't touch what I rem'd out above?

Before:# Check for user request to wait for slow USB devices
if test -n "$WAITUSB"; then
wait_usb
fi
After:
if test -n "$WAITUSB"; then
echo -n "${CRE}{BLUE}Waiting for USB devices${NORMAL}..."
ash -c "sleep 6"
echo "${BLUE}Done.${NORMAL}"
fi

So I should have never touched this section which I put back to the way it was:# Wait for very slow USB devices:
# Host: scsi1 Channel: 00 Id: 00 Lun: 00
# Vendor: Model: Rev:
# Type: <NULL> ANSI SCSI revision: ffffffff
wait_usb() {
case "$(cat /proc/scsi/scsi)" in
*"<NULL>"*|*ffffffff*) ;;
*) return ;;
esac
echo -n "${CRE}${BLUE}Waiting for USB devices${NORMAL}..."
for i in . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .; do
sleep 1
case "$(cat /proc/scsi/scsi)" in
*"<NULL>"*|*ffffffff*) echo -n .;;
*) break ;;
esac
done
echo "${BLUE}Done.${NORMAL}"
}
I found the section you want me to replace did so but getting a different syntax error this time:
/linuxrc: 621: Syntax error "(" unexpected (expecting "fi"
I am assuming this is line 621? I never modifed anything on 621 only what I just wrote now and put it back and did as you said.
I just edited this post I think there is a Quote missing will try that and let you know.
SHould:
echo "${BLUE}Done.${NORMAL}
Be:
echo "${BLUE}Done.${NORMAL}"
??

I missed the closing quote on the first {NORMAL} which I have corrected.The wait_usb function will never be called, so you can delete it or comment it out. Does not matter.
We are really only replacing one line (wait_usb) with three lines:
echo -n "${CRE}{BLUE}Waiting for USB devices${NORMAL}..."
ash -c "sleep 6"
echo "${BLUE}Done.${NORMAL}"

I thought it was missing so just went ahead and added it and ran dsl. I still cannot see the waiting for usb anywhere? It just flips through very fast. I never see any text displayed "waiting"?So basically this entire section can be deleted?
# Wait for very slow USB devices:
# Host: scsi1 Channel: 00 Id: 00 Lun: 00
# Vendor: Model: Rev:
# Type: <NULL> ANSI SCSI revision: ffffffff
wait_usb() {
case "$(cat /proc/scsi/scsi)" in
*"<NULL>"*|*ffffffff*) ;;
*) return ;;
esac
echo -n "${CRE}${BLUE}Waiting for USB devices${NORMAL}..."
for i in . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .; do
sleep 1
case "$(cat /proc/scsi/scsi)" in
*"<NULL>"*|*ffffffff*) echo -n .;;
*) break ;;
esac
done
echo "${BLUE}Done.${NORMAL}"
}
Cannot figure out why I cannot see the "waiting" message? I will try it on another PC to see If I see it there
I'll be right back.
In the meantime I can delete all the script I just displayed? Isn't that USB function called for in other places?
It didn't even work at all on this PC at work. I'll have to try it on the one at home I know it does work on to see if I can see the displayed message.
If you think of anything else let me know and thanks so much for the help. If we can figure out what the problem is it would be great.
By the way I do have a grub boot loader on this version. SHould I try it without that bootloader? It should not matter.

That is the function that can be deleted.It was never a formal part of Knoppix, it was a user contributed hack.
It is only called from one place, which we have replaced with three lines.

ok an update. I have two 64 meg lexar flash drives I created DSL on in a from a dsl boot cd.One has the initrd around 48 meg file which boots on all of the PC's including my D820.
On the other 64 meg flash drives I have as a backup dsl. I removed the initrd from it and put back the normal minitrd.gz but modifed the linuxrc with the latest mod. And also obviously put back the Knoppix image.
Both of them are non grub booting devices and boot from syslinux.
Don't confuse these two flash drives with the ones I have been trying to get to work on the D820 which is a 4Gigs lexar and installed grub on it and did it the Wiki method II from a linux OS.
Thats the one I have been working on with you and it still will not display the waiting message.
On the 64 meg flash I modified the linuxrc file and booted it off a PC I know it works from and I don't see the waiting message there either but it does boot from from this non initrd version. It does not work on the D820.
As I said above I wanted to make sure the grub was not interferring with out tests and its not. I just had to check that.
Anyhow why am I not seeing the message?
Since you said it did not matter I did not delete that whole section you said I could delete.
Any more ideas?

OMG OMG you have done it. It works!!!!! Your a GOD!!!! Thanks so much!!!!!Read a few remarks below:
I know for a fact the 64 meg Lexars that I created dsl on from the Live CD did not work on the D820. That is why I put the initrd on both and I had a second one as a backup.
I don't know how to thanks you but your script works 100%.
I still do not see the message but I don't care at this point because you got it to work.
For the 4gig lexar I don't think the Live CD was able to put dsl on it because of its size so I had to revert to the wiki method:
< http://www.damnsmalllinux.org/wiki....h_Drive >
Method II: Using GRUB as boot loader
making two partitions etc and grub. This USB stick still will not work with the modified script on the D820 although I am able to get it to boot from a couple of other PC's without the modified script.
WHat I have to figure out is how to reinstall dsl onto this 4GB Lexar stick other than the Live CD.
I think the key is to use syslinux? Is that what the LiveCD uses?
Although with syslinux I will not be able to make two partitions on that 4GB flash drive will I? Doesn't syslinux only work it there is one partition on the flash drive?
I'll have to figure out another way to install dsl on the 4GB stick and try the unmodified linuxrc file and yor modified version.
Keeping fingers crossed and thanks again for getting this to work.
Why I never see the message is unclear to me. I tried it both on my D820 which is now boots dsl with your modoifed script and a PC I know that works with or without the modified script. On that PC it always booted dsl fand with the modified linuxrc file I don't see the "waiting" message on that one either?
One more important comment I am using DSL-ISO version 3.4 and not yoru current 3.4.1.
Let me know what other testing you want me to try over the weekend.
I won't probably try anything else until later on tonight or Saturday!!!
THanks again

For your 4GB you can try the new grub usbhdd install script.It is on dsl v4.0c1 and only works when installing from the booted cdrom. It can be found in the usual place on the menu or under Apps Tools
This new script tries to calculate cyclinders and makes 2 partitions. The second partition is a small 50MB for DSL, the first partition is the remaining size of your pendrive and is vfat. This works for me and allows Windows to see the large partiton to share data, etc.
Caution: It is a new and farily untested script.
Don't run it if your system is SATA.
It expects to find the pendrive as sda.
Try it and let me know.

Working on it now. Question can't I clone my now working dsl on the one flash drive using the "dd" command then put that clone on the 4GIger and just partition the rest of it whatever way or partition I want even multiple?How can I do that and copy the boot sector of the working flash drive?
Just curious to see if it will work. I am also testing the release candidate as well.
Posted by emunity on Aug. 19 2007,02:18
Release Candidate 4.0rc1 is DaBomb.Works 100% on the D820. And I noticed the linuxrc script is the same as before we made any changes to it and that script is working 100% on my D820.
So it is something in Release Candidate that has more support for newer devices is why it boots up fine now?
Thanks for all the help. Now I have two great working DSL's
I like Release Candidate1 version 4.0 becaus it supports my broadcom ethernet device.
No support yet I see for the wireless ipw3945 but I have it working on Fedora 7 using the iwl3945 built in kernel module but have to use a Network Manager to connect.
ndsiwrapper in fedora froze my ipw3945 wireless but I am wondering if it might work in this dsl version? Will have to give it a try.
You think that I can get a working kernel driver for the ipw3945? I will have to search your forums for that.
Thanks for the marvelous tech support robert.
For anyone who has a D600 or D800 series Dell Latitude Laptop this thread will be great for them!!
