usbredirserver - exporting an USB device for use from another (virtual) machine

usbredirserver [-p|--port <port>] [-v|--verbose <0-5>] [-4 <ipv4_addr|I-6 <ipv6_addr>] <busnum-devnum|vendorid:prodid>

usbredirserver is a small standalone server for exporting an USB device for use from another (virtual) machine through the usbredir protocol.

You can specify the USB device to export either by USB id in the form of <vendorid>:<prodid>, or by USB bus number and device address in the form of <usbbus>-<usbaddr>.

Notice that an instance of usbredirserver can only be used to export a single USB device. If you want to export multiple devices you can start multiple instances listening on different TCP ports.

-p, --port=PORT
Set the TCP port to listen on to PORT
-v, --verbose=VERBOSE
Set usbredirserver's verbosity level to VERBOSE, this mostly affects USB redirection related messages. Valid values are 0-5:
0:Silent 1:Errors 2:Warnings 3:Info 4:Debug 5:Debug++
