I cannot use my USB mouse because USB 2.0 (NEC chipset) is detected as 1.1. Shall I use ehci instead of uhci which is default?
I used Knoppix 3.1 or 3.2, kernel 2.40.20-xfs.
BTW I got same problem on SuSE 8.1 (2.4.19) and I had to compile 2.40.20 with some 2.5 patches for ehci to solve it.
I see I do not give you folks enought info. This comes from 2.4.21-pre5 kernel with usb-ehci-2.4.21-pre5.patch. Still no results mouse attached to any of two USB ports is dead. It was working with SuSE 8.1 kernel 2.4.20 patched with usb-ehci-2.4.20-pre11.patch. What adiitional info I need to provide?

I would think so. Assuming it's not already listed in lsmod you could check /etc/modules.conf for something likeQuote:

Of course if it's listed there it should load on boot.
If it's not in there you could do a:
# modprobe ehci-hcd
and conversely you can remove it like so:
# rmmod ehci-hcd
Just for the fun of it you could post
cat /proc/bus/usb/devices
It works now. It seems that modern laptops are totally dependant on ACPI. I compiled ACPI into kernel and suddenly USB 2.0 is detected. When I plug in mouse it's appears in usbview.
Here is my /proc/bus/usb/devices

The only potential problem I see is that if you're not using the EHCI driver then your devices can only transfer data at the USB 1.1 rate not at the USB 2.0 rate. I realize this doesn't matter for just a keyboard and mouse but say if you had a hard drive then I assume you'd want to use the faster transfer rate. Glad you got it working though.
UNfortunatelly I got only FireWire hdd to test. With SuSE I did not have to install anything just plug'n'play :-) I am going to test it with Knoppix too.
In case you were not aware there is a module for firewire as well.Quote:
