usb(4): Automagically apply all quirks for USB mass storage devices.
Currently there are five quirks the USB stack tries to automagically detect:
- UQ_MSC_NO_PREVENT_ALLOW
- UQ_MSC_NO_SYNC_CACHE
- UQ_MSC_NO_TEST_UNIT_READY
- UQ_MSC_NO_GETMAXLUN
- UQ_MSC_NO_START_STOP
If any of the quirks above are set, no further quirks will be probed.
If any of the USB mass storage tests fail, the USB device is
re-enumerated as a last resort to clear any error states from the
device. Then the USB stack will try to probe and attach the umass<N>
device passing the detected quirks.
While at it give more details in dmesg about what is going on.
