Another reply to myself: Tested USB device uses a Cypress FX2LP: http://www.summitsoftconsulting.com/picts/iti_pcb_top.jpg I checked the FX2LP specs, and endpoint 1 in both directions is hardwired to wMaxPacketSize of 64. I believe the FX2LP is quite widespread (judging by the availability of a GPL toolchain for it and two CLI tools to send its firmware), so those warnings might cause redundant bug reports.
