Actually, the tests were done with bulk transfer, which works just fine. Isochronous endpoints are in the alternate setting 2. If you pass the argument 'altf=2' to the benchmark app, the error should occur. In my tests, it didn't work: ./Bm-winusb.exe vid=0x4d8 pid=0xfa2e altf=2 LibUsbDotNet USB Benchmark v2.2.9.110 Copyright (c) 2010 Travis Robinson. <libusbdot...@gmail.com> website: http://sourceforge.net/projects/libusbdotnet Benchmark device 04D8:FA2E opened..
