Very well, use usbmon then. You'll need to decode its output
with a script, but the information is there.
For example:
ca6a349c 3984599108 S Bo:004:02 -115 31 = 55534243 49000000 00400000 80000a28
00000000 20000020 00000000 000000
ca6a349c Tag
3984599108 Time
S Send
Bo:004:02
-115 Status (unused)
31 CSW Size = 31
Data:
55534243 Magic
49000000 00400000
8000 Input data transfer
0a 10 byte CDB
28000000 00200000 2000 --
SCSI command: 0x28=READ(10), Block=0x20, Length=0x20*512
