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

usbconfig -h

And:

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:

Here, quirks field doesn't change when I add more quirks.

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.
