Hi everbody, Here is the Output of usbsnoopy when i'm doing datatransfer to my usbdevice. I'm trying to do the same with linux using the usbstress and a control message /snip 00006167 2.12604080 -- URB_FUNCTION_CLASS_INTERFACE: 00006168 2.12606080 TransferFlags = 00000000 (USBD_TRANSFER_DIRECTION_OUT, ~USBD_SHORT_TRANSFER_OK) 00006169 2.12607120 TransferBufferLength = 00000002 00006170 2.12608160 TransferBuffer = d4429fc1 00006171 2.12609200 TransferBufferMDL = 00000000 00006172 2.12609840 00006173 2.12610320 0000: 00006174 2.12611440 0a 00 00006175 2.12612480 UrbLink = 00000000 00006176 2.12613520 RequestTypeReservedBits = 22 00006177 2.12614480 Request = 09 00006178 2.12615520 Value = 0200 00006179 2.12616640 Index = 0000 00006180 2.12923520 00006181 2.12924000 <<<<<<< URB 41667 coming back... 00006182 2.12925360 -- URB_FUNCTION_CONTROL_TRANSFER: 00006183 2.12926720 PipeHandle = d5f9ac2c 00006184 2.12928480 TransferFlags = 00000002 (USBD_TRANSFER_DIRECTION_OUT, USBD_SHORT_TRANSFER_OK) 00006185 2.12929600 TransferBufferLength = 00000002 00006186 2.12930640 TransferBuffer = d4429fc1 00006187 2.12931760 TransferBufferMDL = d5e99a80 00006188 2.12932720 UrbLink = 00000000 00006189 2.12936640 SetupPacket : 21 09 00 02 00 00 02 00 /snip end
With the information of this thread http://www.geocrawler.com/mail/msg.php3?msg_id=5195912&list=2571 i build an controlmessage which should do the same. /* CONTROL MESSAGE */ int usb_control_msg(unsigned char requesttype, unsigned char request, unsigned short value, unsigned short index, unsigned short length, void *data, unsigned int timeout) { struct usbdevfs_ctrltransfer ctrl; int i; ctrl = (struct usbdevfs_ctrltransfer){ requesttype, request, value, index, length, timeout, data }; i = ioctl(dev->fd, USBDEVFS_CONTROL, &ctrl); printf("Control Ioctl: %d\n",i); if(i < 0) printf("USBDEVFS_CONTROL(rqt=0x%x rq=0x%x val=%u idx=%u len=%u) error %s\n", requesttype, request, value, index, length, strerror(errno)); return i; } ret = usb_control_msg(0x21, 0x09, 0x0200,0x0 , 0x0,&buf,timeout); Before i did the control message i opened the device, claimed it and set the configuration(0). Everything successfull. Here is the output of my program: Control Ioctl: -1 USBDEVFS_CONTROL(rqt=0x21 rq=0x9 val=512 idx=0 len=0) error Connection timed out Does anybody know why the ioctl wont do it? Can somebody give me some debug starting points?
