Particularly interesting is this transfer: 00000302 0.07208179 >>>>>>> URB 273 going down... 00000303 0.07209184 -- URB_FUNCTION_VENDOR_DEVICE: 00000304 0.07210442 TransferFlags = 00000000 (USBD_TRANSFER_DIRECTION_OUT, ~USBD_SHORT_TRANSFER_OK) 00000305 0.07211587 TransferBufferLength = 00000020 00000306 0.07212676 TransferBuffer = 812c34e8 00000307 0.07213682 TransferBufferMDL = 00000000 00000308 0.07214604 00000309 0.07227315 0000: 08 01 2c 01 2c 00 00 00 00 0a 82 00 32 00 00 00 00000310 0.07241256 0010: 10 30 20 00 00 64 00 64 00 64 00 00 00 00 00 00 00000311 0.07242205 UrbLink = 00000000 00000312 0.07243239 RequestTypeReservedBits = 40 00000313 0.07244245 Request = 04 00000314 0.07245278 Value = 2505 00000315 0.07246284 Index = 0000 00000316 0.08477949 First byte 0x08 could be color depth. Next ones are 0x12c=300, probably resolution x and y. Value 0xA82=2690 could very well be the width of the scan, about 9 inches or about 23 cm. Also three times 0x64=100 looks promising. Some value for each color component (R, G, B)? Kind regards, Bertrik
