Hi, On my board, my musb works as host. my kernel version is 3.4.0.
The host cannot enumerate some low speed mouse normally,but if I
add an extersion cord (abour 1.5m) between the host and device, the
mouse can work normally.
If the enumeration fails, there is always a babble interrupt happen just after
the USB reset ,and the session would be stop(seems automaticly stoped by
the IP core).
>From the sniffer, if the enumeration success, there is an EOP just after
the usb reset(about 2us), but if fails, there is no EOP,then babble
interrupt issued.
So anyone please give me some clue to dig?
