You can use usbconfig to add quirks on the fly. See:
usbconfig -h

man usbconfig
Tried that, but it doesn't work for me or I'm messing things up...
usbconfig -d 3.3 add_quirk UQ_MSC_NO_SYNC_CACHE
And errors continue to show up. The man page also is kinda short on data.
After setting the quirk, you need to reset or re-attach the USB device.
Not a good behavior for me. What if I need to boot from one? Most FS
don't like been pushed off device.
But this doesn't work too.
usbconfig -d 3.3 add_quirk UQ_MSC_NO_TEST_UNIT_READY
usbconfig -d 3.3 reset
Gives me:

Mentioned patch was looking like:
USB_QUIRK(ALCOR, TRANSCEND, 0x0142, 0x0142, UQ_MSC_FORCE_WIRE_BBB,
UQ_MSC_FORCE_PROTO_SCSI, UQ_MSC_NO_GETMAXLUN, UQ_MSC_NO_SYNC_CACHE),
But I don't understand what should be set for my flash at 3-4 places...
They are covering some range but inspecting my flash I don't see
something close to the 0x142.
This is bcdDevice range. So, change first 0x0142 to 0x100 for your
flash drive or add another quirk (before quirk for all TRANSCEND's)
with 3-4 places set to 0x100.
