Ah, it's good to hear that there's reported succes with USB on Xen,
too bad I'm not currently able to repeat that though :-(
I'm running this on an Asus A7M266D dual-athlon system, the USB2
card came with the system, is there anything special with this system?
I also tried to insert the cmpci driver (there are two such devices in the
system; one onboard, and one PCI card), and it also complains with a
similar "No IRQ known for pin A of device 03:04.0" message.
How does Xen deal with shared interrupts? I do have a lot of devices
in my system (2 Graphic cards, an USB2 card, a sound card, an ISDN card,
and a TV capture card).
Could the "Plug-and-Play OS" setting in my Bios have any impact on Xen?
(since it seems that some IRQs are not assigned...?)
Here's the output I get, I tried to load uhci, then usb-uhci (the alternate
driver), and last the ehci driver. All failed :-(
