Earlier, I didn't know which list to email, so I wrote to Martin K.
Petersen (who pointed me to the lists when I asked where I can post
publicly), and he made this observation on the above quoted text:
"Linux can run USB block devices in either legacy or UAS mode.
Chances are this device is being driven in usb-storage mode. We
usually have quirks based on the model strings that decide whether
to use one or the other."
