	Hello,

	the following test is failing in sanei_genesys_read_gl847_register():  
if((value & 0xff00) != 0x5500)
    {
      DBG (DBG_error,"sanei_genesys_read_gl847_register: invalid read, scanner 
unplugged ?\n");
      status=SANE_STATUS_IO_ERROR;
    }

	While the bytes (00 55) from USB are correct. I think this is an 
endianess issue in code. What is the CPU running the code ?

Regards,
	Stef
