You will have to use a USB bus analyzer. Another possibility is to set up a virtual Windows system inside your Linux host. Then try running the USB CV program on the virtual machine, and use usbmon on the host system to capture the USB traffic. I don't know if that will work, but it might. > Ok.

Perhaps you will recognize this answer (I have sent it several times before): I can't tell what is happening without seeing _both_ the log file on the gadget _and_ the usbmon trace on the host.
