Hi�� Now I��m porting USB Host Controller Driver for
SA1111. Root hub operates well. When device is
inserted, root hub detects new device. But get_descriptor() doesn��t operate. After usb_submit_urt(), in schedule_timeout()
timeout occurs. I think that Interrupt doesn��t occur. In order to properly operate SA1111 USB Host
Controller, I have to specifically setup? Is there anybody met same problem? Please, help me. Regards�� |
