Hi,
I've got a SIS735 chipset and i'm therefor using the usb-ohci module.
After upgrading from 2.4.21 to 2.4.22 my USB doens't work anymore.
lsusb doesn't show any devices - find /proc/bus/usb too.
On my laptop everything works fine with 2.4.22, but it has an intel
chipset and uses UHCI instead of OHCI.
I read the Changelog and didn't find anything that looks like the reason
for my trouble. I double checked that every module is there in my 2.4.22
config. I even did "make oldconfig" after copying my config from the
2.4.21 kernel.
With 2.4.22 my USB just look dead.
I also tried to copy usb-ohci.c from 2.4.21 to 2.4.22 and recompiled the
kernel. Nothing changed (the diff wasn't that big, so i tried that).
Any ideas? If you need more information or just want me to try a patch
just ask.
Thx
Sven

Well, Thx. I've got the same board (K7S5A), so it should work for me too.

It should be there eventually, the core ACPI guys understandably decided to
keep it back for some more testing because one bit of it was quite large.

I got the same probleme with K7S5A/SiS735 and it doesn't come from USB.
I found that the acpi upgrade between 2.4.22-rc2 and 2.4.22-rc3 break the USB detection. I made a fall-back diff about this.
I discussed about this with Andrew de Quincey on acpi mailing-list. His last acpi global patch correct this problem too but I don't know if it will be implemented.
Look at acpi archive (last week):
