--- Comment #19 from Brett <vbasiccd@msn.com> ---
FYI, I had the same issue with a Sandisk iXpand flash drive on 14.1-RELEASE-p6.
Below is the output in /var/log/messages:

usb_msc_auto_quirk: UQ_MSC_NO_GETMAXLUN set for USB mass storage device SanDisk

I added the following line to /boot/loader.conf and then rebooted.

hw.usb.quirk.0="0x0781 0xcffb 0 0xffff UQ_MSC_NO_INQUIRY"

Now the drive mounts properly. Thanks for the tip!
