Hi,

It looks like the auto-quirk code for USB mass storage, which was 
activated recently is changing the quirks for your device. The INQUIRY 
command is expected to fail. Does the device work, or are you just 
worried about the warnings in dmesg?

You can get more information by setting:

sysctl hw.usb.usb.debug=15

while plugging your device. Search for "msctest" keyword.

QUIRKS 0x4101 are:

#define NO_SYNCHRONIZE_CACHE    0x4000
#define NO_GETMAXLUN            0x0100
#define NO_TEST_UNIT_READY      0x0001

If you add this quirk, the msctest logic will be disabled:

usbconfig -d X.Y add_quirk NO_SYNCHRONIZE_CACHE

You need to replug the device after adding the quirk.

See also:

sys/dev/usb/quirk/usb_quirk.c

For permanent quirks.
