More USB questions (for the MPC8xx)

[Kári Davíðsson]

Hi,

I was also just getting time outs (error -110) if I applied both of
Roman's patches. If I only applie patch one, i.e. the TIMER1 patch
I have more luck, i.e. the keypspan is identified but the firmware
can not be written to the keyspan and therefore (I think) the
identification fails. The MS USB mouse is not identified, the SOF
packets are still there but no other data.....

If you have both of romas patches try to remove the virtual root hub
patch and see if you have more luck.

K.D.
