Maybe you have the same pb as mine. I don't think sharing irq is the
problem. I looked briefly at the usb-ohci.c code. In my case, I got the
same pb as you:
USB device are not recognised as they are plug in. It complains about URB
timeout and looking deeper, it times out when sending the "usb set
address" request (ie the first usb request sent to the device).
I added a lot of traces in hc_interrupt() and just discovered that the
address seen in ohci->hcca->done_head does not match any of the URB sent
(TD ptr).
I'm thinking about PCI bus pb (SiS hardware? mine is UMC.). In your case,
does it work under windows? (in my case, I do not have enought disk space
to install windows).
