"USB flash drive" is a little generic. Bottom of the barrel in quality and price are memory sticks like the Sandisk Ultra Fit mentioned and they don't (usually) fall into any category where discard or trim is relevant. A USB SSD, usually yes. Depends on the controller chip though, it needs to be able to pass the trim commands to the drive properly.
