Then I tried to use libusbdotnet under Linux to see if the firmware works under Linux (libusbdotnet relies on libusb-1.0 or libusbx under Linux). And it seems to work. And I tried your isoc program and it has the problem you mentioned that the read does not work. So from my test results, it seems that your host program needs some modification to get it work with the firmware. mcuee@ubuntu:~/Desktop/build/libusbdotnet$ sudo mono Bm-libusbk.exe list mode=async buffercount=2 verify LibUsbDotNet USB Benchmark v2.2.9.110 Copyright (c) 2010 Travis Robinson. <libusbdot...@gmail.com> website: http://sourceforge.net/projects/libusbdotnet 1. 0402:9665 XPA3H1NVA - 1.3M WebCam 2. 046D:C52F Logitech - USB Receiver 3. 04D8:FA2E Travis Robinson - Benchmark Device 4. 046D:C058 Logitech - USB Optical Mouse 5. 0CF3:3005 6. 1D6B:0002 Linux 3.5.0-22-generic ehci_hcd - EHCI Host Controller 7. 1D6B:0001 Linux 3.5.0-22-generic uhci_hcd - UHCI Host Controller 8. 1D6B:0001 Linux 3.5.0-22-generic uhci_hcd - UHCI Host Controller 9. 1D6B:0001 Linux 3.5.0-22-generic uhci_hcd - UHCI Host Controller 10. 1D6B:0001 Linux 3.5.0-22-generic uhci_hcd - UHCI Host Controller Select device (1-10) :3 Benchmark device 04D8:FFFFFA2E opened..
