this quirk fixes the issue for me - both LUNs are detected and two umass
devices appear.
I submitted a patch in the following PR:

Looking into this further, I think that the issue is down to Garmin

In reply to the SCSI INQUIRY command, the HISUP bit is not set. This
means that single level LUN structure is used (which appears to be all

55 53 42 43 03 00 00 00 18 00 00
