Hi All,
I am porting linux to a custom ARM board. It has an onboard PCI USB hub. The
hub
is detected properly but when I plugin a keyboard it give the above mentioned
error. ACPI is not enabled.
Also, whenever I plugout the device and plug it back, i can see that the /proc
interrupts for the USB is incrementing (spew enclosed)
Enclosed is my spew. Looking forward for links / pointers to solve this
problem.
