ctrlX QEMU USB devices

[WolfgangDannert]

Hello,

how can a USB device be mounted in the ctrlX QEMU VM and used inside?

I have tested the procedure in the QEMU documentation (https://qemu.readthedocs.io/en/latest/system/devices/usb.html?highlight=ICH9#companion-controller-su...) but I only see the USB controllers and not the USB devices.

Detected USB controllers in dmesg:

Here are the different (separately) parameters I tested in the launch.bat file:

...
-usb ^
-device usb-host,vendorid=0x1234,productid=0x5678 ^
-device usb-ehci,id=ehci ^
-device usb-host,bus=usb-bus.0,vendorid=0x1234,productid=0x5678 ^
-device usb-host,bus=ehci.0,vendorid=0x1234,productid=0x5678

-device qemu-xhci

The vendor and product ID are sample values. For testing I took the values from the USB stick I want to use.
With an Ubuntu 20.04 in an Oracle VM I can access the USB device. With QEMU I have not been able to do this yet.
Can someone help me here?
Thanks

Hello, 

I also tried to get a usb-device into my qemu App Build Environment without success. It looks the same like your output looks like. Unfortunatly I can't figure out the reason for this at the moment. 

In the meenwhile you could also use your VirtualBox Ubuntu20 VM as a build environment. You could look at this documentation on how to do that. 

Best regards,

Nick

Any news here or can this topic be closed?

A USB device could be connected and detected within the VirtualBox Ubuntu20 VM.

The problem persists in the QEMU VM.

The use of the QEMU VM is still the target.
