Hi,
I was getting the same sort of problems with the latest backport patch,
although I have a uhci controller rather than a ohci controller. I found
that if I build everything as modules rather than directly into the kernel,
then the mouse works with the backport patch. The problem seems to be that
the kernel has no clue about char-major-13 when the usb stuff is compiled
directly into the kernel. When I look at /proc/devices with the usb stuff
compiled directly into the kernel, there is no entry for char major 13, but
when usb is compiled as modules, there is an entry for char major 13.
As far as Brad's question about the contents of /proc/bus/usb/devices,
I compared the output from the 2.2.15pre20 + the latest backport patch
to what gets generated from 2.3.99-pre6 final, with both of them having
the usb stuff built directly into the kernel, the contents of
/proc/bus/usb/devices is identical. Also, the contents of
/proc/bus/usb/devices is identical whether I build 2.2.15pre20+backport patch
as modules of directly into the kernel.
