Hello,

I'm trying to use a USB device in a VM, specifically a fingerprint reader.

To access this VM, I'm using FreeRDP 1.2x, on a Pales server.

First, I identified the USB ID using the lsusb command, and I got this ID: 
1b55:0840

Then, I use the freerdp command line to see all messages from the RDP 
connection:
/opt/freerdp-nightly/bin/xfreerdp /v:<VM Name> /u:<user> /p:<password> 
/d:<domain> /dvc:urbdrc,dev:1b55:0840

the above command opens the RDP session, but it can't detect the USB device.

After checking the messages in the uxterm, I found this:

[10:53:37:184] [3608:3609] [INFO][com.freerdp.client.common.cmdline] - loading

Would you help me to figure out how to do this USB redirection, please?

Thanks & Regards.
