Vojtech,
I duplicated Harold's report and then made a few changes.
Maybe it will be enough to help make a real patch.

Hi,
Well, it seems my problems with the backport patch goes away
if I build all the usb stuff as modules rather than directly into
the kernel.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
On a SuSE 6.3 (2.2.13) system, Pentium 180 (my ancient home
system), UHCI add-in PCI adapter, I built vanilla 2.2.14 +
the USB backport patch, first as modules:
Hub/keyboard combo worked right away. Printer is recognized
(I didn't try to print).
Then I switched to USB in-kernel: UHCI, printer, usbkbd (HIDBP),
& usbmouse (HIDBP).
When I rebooted, my PS/2 keyboard was dead, but the USB keyboard
was working. Since my boot scripts start gpm for a PS/2 mouse
which wasn't there, maybe that has something to do with it.
Anyway, I killed gpm (from the USB kbd) and then my PS/2 kbd
worked OK.
However, my mouse wasn't recognized and there was no char major
13 listed in /proc/devices.
Until I modified usb-core.c to call input_init() and made simple
changes to input.c [input_init() not static; commented out
module_init() and module_exit()]. So my first guess is that
it's an init order problem....
On a different subject, it seems that I recall someone saying
that usbdevfs didn't work (or was empty) on the latest
(2.3.99-pre6-7) backport, but I used it both with USB as modules
and USB in-kernel with no problems.
