It does work, though, when I keep my hands afk. I also increased the wait time from 5 seconds to 20 in drivers/usb/host/pci-quirks.c but that didn't change anything. I guess the bios won't release OHCI in order to be able to serve keyboard input without usb hid drivers once I hit a key when bios is still in charge. But I looked around and couldn't see any ill effects so I'll stop bothering you with this ;-) Regards Sebastian Hardware: * 32bit Sempron * Shutte AN35N NForce2 mainboard ...
