Laptops :: Dynex USB 2.0 Notebook Card



I bought a Dynex USB 2.0 Notebook Card (DX-UC202) at BestBuy and cannot get it to do anything on DSL. DSL seems to recognize it because when I do <<lsusb>> it shows that there are USB ports (but does not show anything attatched to them even when USB devices are plugged into it). I tried my Lexar JumpDrive in it about a month ago when I first got the Dynex card, and it not only didn't show up when I did <<lsusb>> but actually went as far as to delete everything on the JumpDrive and completely nuke the JumpDrive to the point that now even Windows XP computers no longer recognize it when I plug it in to a USB port. I plugged in my HP USB printer today to see if it would recognize that, but <<lsusb>> didn't even show it plugged in. What do I need to do to get this USB card working? According to <<lspci>> it uses the NEC Corporation USB 2.0 (rev 04) chipset. When I google search this chipset all I find is stuff about Apple laptops, which is not much help.

NEC is a very common chipset for USB2.0

In fact, most hardware geeks prefer NEC to the more troublesome VIA chipset for example.

I have used a NEC USB2.0 addon PCI card (desktop PC, not laptop PC) with DSL and had no problems.

The only thing that I needed to do was type

sudo su
modprobe ehci-hcd
exit
exit

before I plugged in my USB drive and I got high speed connection.

Otherwise, it still worked but I did not get the high speed, just the slower USB 1.1 speeds.

Maybe you can find some more information by typing

dmesg | more

to see the bootup messages.

Does using a different PCMCIA slot, or does ejecting and reinserting help?

A Mepis Linux user has reported success with this card, so it is compatible with Linux.
