 Hi,
 
 This device is already exist as:
 
 product HUAWEI E3131            0x1506  3G modem
 
 Can you update your patch to use this definition instead?
 
 Where did you obtain the SCSI command from? I suggest that the existing 
 HUAWEI SCSI quirk issue the new command after the existing one.
 
 Update your patch and I'll have a look again.
 
 --HPS
