I have read in the archives about people having similar problems as me
when trying to use USB on a MIPS machine.
I get an oops as soon as I plug anything into the USB port.
This is kernel 2.4.0-test5.
I also backported the USB from 2.4.2 to 2.4.0-test5 and I get the same
problem.
Any help is appreciated.
