I am porting pxa27x driver to linux-2.4.20 using gadget framework to support rndis. pxa27x driver nearly works. The driver init procedure is ok. The problems appear after windows 2000 pc send a set_configuration request.I could read out the configuration, interface, alterinterface from UDCCR as 2,0, 0. All data before set configuration request is normal as I expected, that is received data is same as bushond shows what pc sends.
But after handling the set configuration request,(No configuration error by checking UDCCR_EMCE).endpoint 0 continue received a class-specific request(IN) ( its payload of 24bytes), The 8-byte class-specific request's content is as expected . but the 24bytes' data following class-specific request is not what bushound shows.(but length is same as udcbcr0 value), They are all same value as 0xe8600300 after read out from udcdr0(udc endpoint 0 data register). I am not sure if this question has relationship with improperly dealing with SET_CONFIGURATION request? Before reading the 24bytes payload , ep0 is in EP0_OUT_DATA_PHASE, UDCCSR0 with UDCCSR0_OPC set(this trigger a interrupt ==>> handle_ep0) Anybody very familar with pxa27x usb controller?
