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? -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
