If anyone has any objections, please let me know. ------------------ From: Chen Changcheng [ Upstream commit 955a48a5353f4fe009704a9a4272a3adf627cd35 ] The optical drive of EL-R12 has the same vid and pid as INIC-3069, as follows: T: Bus=02 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 3 Spd=5000 MxCh= 0 D: Ver= 3.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 9 #Cfgs= 1 P: Vendor=13fd ProdID=3940 Rev= 3.10 S: Manufacturer=HL-DT-ST S: Product= DVD+-RW GT80N S: SerialNumber=423349524E4E38303338323439202020 C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=144mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.)

When performing an erase operation, it will fail, and the reason for the failure is as follows: [ 388.967742] sr 5:0:0:0: [sr0] tag#0 Send: scmd 0x00000000d20c33a7 [ 388.967742] sr 5:0:0:0: [sr0] tag#0 CDB: ATA command pass through(12)/Blank a1 11 00 00 00 00 00 00 00 00 00 00 [ 388.967773] sr 5:0:0:0: [sr0] tag#0 Done: SUCCESS Result: hostbyte=DID_TARGET_FAILURE driverbyte=DRIVER_OK cmd_age=0s [ 388.967773] sr 5:0:0:0: [sr0] tag#0 CDB: ATA command pass through(12)/Blank a1 11 00 00 00 00 00 00 00 00 00 00 [ 388.967803] sr 5:0:0:0: [sr0] tag#0 Sense Key : Illegal Request [current] [ 388.967803] sr 5:0:0:0: [sr0] tag#0 Add.

For the EL-R12 standard optical drive, all operational commands and usage scenarios were tested without adding the IGNORE_RESIDUE quirks, and no issues were encountered. It can be reasonably concluded that removing the IGNORE_RESIDUE quirks has no impact.
