It seems not to be quite that simple :( When I plug it in and turn
it on, the console reports (on 6.1):
umass0: vendor 0x0784 product 0x4300, rev 1.10/3.00, addr 2
umass0: Get Max Lun not supported (SHORT_XFER)
umass0: Invalid CSW: sig 0x43425355 should be 0x53425355
umass0: Invalid CSW: sig 0x43425355 should be 0x53425355
umass0: Invalid CSW: sig 0x43425355 should be 0x53425355
umass0: Invalid CSW: sig 0x43425355 should be 0x53425355
umass0: Invalid CSW: sig 0x43425355 should be 0x53425355
The "Invalid CSW" message appears to originate about 2/3 of the way
into umass.c:umass_bbb_state(), and it looks as if there is a quirks
mechanism to override it, but how do I go about configuring it?
The handbook, umass(4), and "apropos quirks" all come up empty.
In case it matters, this is the report when I turn it off:
umass0: at uhub0 port 2 (addr 2) disconnected
umass0: detached
