You shouldn't use the FIX_INQUIRY flag, and you probably don't need the
SINGLE_LUN flag either.
I didn't think they would be particularly useful, but those two
options are the only set where I can get some recognition of the
device (name, size, and a /dev node). Otherwise, I experience four
USB device resets and little more. I removed those options for the
tests below.

Turn on CONFIG_USB_STORAGE_DEBUG to get a better idea of what's happening.
With both US_SC_SCSI and US_SC8070 (no LUN or INQUIRY options), I get
the attached set of errors up to when I disconnect the device.
