USB in Host?

[KenHorse]

Do I need to do anything special to access a USB device from the host?

lsusb shows it but I can't seem to access it from a program running on the host

The device is 004

ls /dev doesn't show it:

Hello,
have you tried following this guide https://pve.proxmox.com/wiki/USB_Devices_in_Virtual_Machines ?
An example of a command could be: qm set XXX -usb0 host=0d8c:013a, where XXX is the number of the VM to which you want to connect the device.

As I posted, I'm trying to make it accessible to the HOST, not a VM

Check the output of dmesg for entries related to your device. What device is this? The kernel seems to detect it as sound cardC-Media Electronics, Inc. USB PnP Sound Device.

Well the device is recognized, can you see it in the output of, e.g. pactl list sinks short or via alsamixer?

 

[KenHorse]

Guess I'll have to install alsamixer and see. I'll report back
