Windows 10 Standalone VM don't see USB devices

Hello to everyone.
I created a standaloneVM with windows10 to using exclusively offline for office and other shitty utility programs. Not a fan of microsoft at all!

Im using Qubes 4.2 and stacking at this following problem: Win10 qube don’t see my usb drive after i link it to this qube. Don’t care about other problems like audiothat doesn’t work or video drivers etc etc since I just need a usb connection to work with my work documents.
There are many guides to solve the usb problem but i wasn’t able to fix it becouse I don’t know which guide to follow and i made a mix of them typing commands from many guides in dom0. (bad decisions btw)

First of all, Is it possible to attach usb to win10 qube propertly without qwt installation?
If yes how can I remove QWT I previously installed from dom0?
Then, what I have to do exactly stepbystep to fix it without QWT installed on qubes?
I’d have the same problem with win11 instead of win10? (I didn’t install win11 becouse it forced me to have an internet connection and a microsoft email… bleh)

Thank you to all :slight_smile:

You can use USB devices without QWT if you enable stubdom-qrexec feature for your Windows qube in dom0:

qvm-features win10 stubdom-qrexec 1

qvm-features – manage domain’s features — Qubes Admin client v4.3.7-0-g2a57695 documentation

You want to remove it from dom0 or you’ve installed QWT in Windows qube and you want to remove it from Windows qube?
The QWT package in dom0 is just installing the ISO file in dom0 containing the QWT installer that you can attach to Windows qube to install the QWT there.
So there is no need to remove the QWT from dom0 specifically since it’s not a danger for dom0.
But if you still want to remove it, you can run this command in dom0:

sudo dnf remove qubes-windows-tools

Yes.

Did you try to attach the device from the Qubes Devices widget in systray → USB Devices block or from the Qubes Devices widget in systray → Data (BLock) Devices block?

So which is it?
Qubes Devices widget in systray → USB Devices block
or
Qubes Devices widget in systray → Data (BLock) Devices block

First should work, second won’t work without QWT.

You are so right man! now it works, I made mistakes and I tried many times “Data (Block) Device” thinking is the same and for this reason didn’t work. Thank you so much!
