Hmm, dev-storage should be fine with the packet being larger than
needed.  It'll actually do a short transfer then.  So I suspect the
patch just papers over the underlying issue.

Can you post a trace of this?

(dev-storage has no trace support, so I think tracing usb_dwc2* to
 stderr and enable DEBUG_MSD in dev-storage.c works best)

take care,
