Hi... I asked this a long time ago when I just got subscribed, but got no answer... I guess I'll have to ask again and try to be specific/simpler this time.
When my kernel 2.6.5 tries to detect the modem, it goes on like this:
//---------------------------------------------------------------------------

Pretty much says that my ohci_hcd driver couldn't probe the hardware.. and the error
code is -75 (what does -75 means anyway?). I've been having this problem since 2.6.1,
I think (it was working before... but strangely enough, my cable modem stopped working
the day I accidentally unplugged it... ever since then it won't work. I tried
connecting to other usb ports, I even got a new usb cable to no avail).
Strange thing is that the kernel 2.4.25 has no problems loading my cable modem, EXCEPT
after rebooting from a 2.6 kernel, when I do a 2.6-> 2.4 change, my cable modem also
fails to be detected!
//---------------------------------------------------------------------------

//---------------------------------------------------------------------------
If I rmmod CDCEther and then modprobe CDCEther the modem gets correctly identified. So
my guess is that ohci_hcd is doing "something" to my cable modem and is screwing it
up... and it doesn't gets fixed until I unload/reload the 2.4's CDCEther driver =/
Any ideas on what I should try/do? I've been trying with every 2.6 kernel
release until now... and my cable modem fails the same way everytime. Is there some
sort of configuration perhaps stored somewhere on my disk which I can just delete and
then retry? (I wonder this because of HOW my cable-modem stopped working so
mysteriously after unplugging it so long ago).
The motherboard is a NForce2 based one (XFX Mach4 NF2S-ALH)
