I have been having problems getting the 2.6 kernel to properly identify my

same here; never found anything useful Googling

If the printer and
scanner are not plugged in the computer will boot normally but only
occasionally can I get "/etc/init.d/hotplug restart" to complete
successfully.

never worked for me

This weekend I downloaded Knoppix and found something interesting when
booting in the "expert26" mode.  Hotplug will find the USB ports but not
load anything.  It then says firewire is found on my computer (there is no
firewire capability on this motherboard and I own no firewire devices) and
goes on to "configure" the firewire devices it finds.

ditto on firewire (non-existent);
Once booted I can install my printer but it immediately says the printer
is paused as no such device is available on this machine.

Why this is so interesting is because I compiled my own 2.6.8 kernel
using a Knoppix .config file.  Apparently there seems to be a bug either
in the hardware on my motherboard (Gigabyte GA-7IXE4) or in the way the
Knoppix .config file is recognizing my hardware.

Knoppix indeed recognized and initialized my shiny new Sandisk 8-in-1 and
Canon A-75! What's this? uname -r shows a 2.4 kernel- hmmm,
musta entered boot params incorrectly- reboot to 2.6 kernel- same probs.
as in Sarge. Mandrake Move is only live cd I tried with 2.6 kernel that
actually worked, and it worked perfectly (re usb devices; actually, it's
pretty slick overall, and as an (ex) Drakie, I got a bit misty). However,
unable to translate Mandrake to Debian, so a reversion to a 2.4 kernel was
in order (now experiencing a more joyful state of mind). BTW, I'm using
ga-7ixe, so will be keenly watching thread- good luck to us both!!




Hmmm... This looks like a group of Gigabyte mobo users all having the same problem. I wonder if the bug is in the usb controller Gigabyte is using or in the kernel? I also get some error messages related to usb with a 2.4.27-1-k7 Debian-built kernel too. However, once it boots all usb devices work correctly. The error on the 2.4 kernel during boot is usb_control/bulk_msg: timeout. It will timeout anywhere from 4 to 10 times before everything loads properly. My printer is an HP Deskjet 895C and my scanner is an HP 6200 C. Oh, and about my mobo having a lan port as a firewire port, well, this mobo was made before firewire even existed.
