I tried different usb2 devices with the last 2.0rc1 version and none seem to function at Hi-speed but all down to usb1...

Has anyone got a hi-speed USB stick working this far with any DSL distribution? Knoppix v3.9 works fine but that's also with the new 2.6. kernel...

I just do a modprobe usb-storage and then mount /dev/sda1.

Am I using the wrong module?

Try:

Unplug the device

sudo su
modprobe ehci-hcd

Plug the device back in

wait a few secs

mount it.

"Why is it not loaded automagically?" you ask?

Because some manufacturers of popular motherboard chipsets *cough*nVidia*cough* do not use standard ehci controllers on all of their usb2 controllers, and loading the ehci module can cause these nonstandard ports to not function at all.

So we think it's better to have functionality on all ports, even if it's slow, by default.

A compromise solution for the future could be to add a new cheatcode called "usb2" that would be checked by the linuxrc or later on by one of the init scripts and then automatically modprobe the ehci-hcd module if requested.

Just a thought.

I have DSL 2.0RC1 installed on two USB sticks - one USB 1.1 and the other USB 2.0.

At the initial boot, when minirt24.gz and linux24 load, things go much faster with the USB 2.0. When the kernal loads, both USB sticks take the same amount of time (+/- 3mins).

Is the above due to the ehci-hcd module? If so, is there anyway to load it prior to loading the kernal in order to speed things up?
