I can bring up the gadget in full speed mode now, so the SCSI_READ_10 command problem is fixed. It is caused by an error interfacing to hardware. Now there is another problem with SCSI_MODE_SELECT_6 command, when in full speed mode, the data for SCSI_MODE_SELECT_6 command is 72 byte, and somehow the gadget is reset. Is it because gadget is not able to handle the amount of data? Please see the attached gadget log. Normally, in high speed mode, the data of SCSI_MODE_SELECT_6 command is 24 byte. Thanks, victor
