2.6.9-rc1-mm4 - USB suspend issues

[Lukas Hejtmanek]

Hello,

I've tried suspend/resume code of USB devices. Unfortunately it does not work :(

First it complains that USB device has 0 interrupts (as module was not used
since start but it was loaded)

Second I got following messages:

After resume it disables IRQ 11 for USB and that IRQ is shared with eth0:
