I have found that if the bios setting :- "MPS Version Control for OS" is set to 1.4, then the usb stuff appears to not receive any interrupts. If set it to 1.1 then all is fine. I assume that no interrupts is the problem, i get a load of timed out messages and an error 110.
Is this a known thing ? I noticed that it also allocates interrupts differently, ie my tv card gets assigned irq 9 when MPS is set to 1.1 as below, but when its set to 1.4 then it gets assigned to IRQ 18.
