Description Alexander Farley 2004-02-15 01:16:04 EST

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040115

Description of problem:
USB devices do not seem to be recognized by kernel-2.6.2-1.79. With
the same system using kernel-2.4.22-1.2166 all of the devices are
recognized and work flawlessly. Devices include a scanner, digital
camera, usb flash drive, logitech webcam, and a usb mouse.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Try use any usb device with a 2.6.x kernel
2. Devices are not recognized

Actual Results:  USB devices are not recognized and cannot be used.

Expected Results:  USB devices would be usable as they are in 2.4.x

Additional info:

Using usbview yields an error messages that /proc/bus/usb/devices
cannot be accessed because it does not exist. However, I do not know
if this directory has changed with the upgrade to 2.6.x kernels.

Do you have an 'alias usb-controller <something>' in /etc/modprobe.conf?
Comment 2 Alexander Farley 2004-02-16 12:43:29 EST
Yes, I have:
alias usb-controller usb-uhci
alias usb-controller1 ehci-hcd

lsusb produces: 
cannot open /proc/bus/usb, No such file or directory (2)

Only input and pci folders are in the /proc/bus directory.

I tried commenting the two out, but that had no effect. lsusb produces
the same error.
Comment 3 Arjan van de Ven 2004-02-16 12:44:54 EST
that's it then; it's supposed to be
uhci-hcd not usb-uhci ....
Comment 4 Alexander Farley 2004-02-16 13:14:36 EST
Indeed the change solved the problem. However, the module is not being
automatically loaded during boot-up. I had to manually load the
module, which then allowed me to access the usb devices. 

Shouldn't kudzu take care of the uhci-hcd entry if there has been a
naming change between kernels 2.4 and 2.6?
