Try increasing the amount of RAM in the HVM qube settings. It worked for me.

Hello, thank you for the tip !
How do you upgrade your firmware ?
In firmware process the usb “restart” to install and I loose the USB connection.

I’m spamming this on all the Trezor threads I can find. I could never get a good solution, so I worked with AI to diagnose and create a working solution. It’s a python script, it depends on python3-trezor and python3-libusb1. The flow is 1) plug trezor in, unlock, and attach to qube, 2) run script, 3) use trezor suite, or launch a chrome-based browser with “–disable-features=LocalNetworkAccessChecks“ and then the trezor website and metamask should work. The script has nice long comment docs explaining everything in it. I don’t know how long this will be viable for, but at least for the moment, it’s a relatively easy solution for getting the trezor to work.

Trezor HTTP bridge for Qubes OS.

Makes Trezor hardware wallets work with Trezor Suite and MetaMask (and
anything else that uses trezord or Trezor Connect) on Qubes OS, where the
Trezor is attached to an AppVM via USB-over-IP (qvm-usb).

The problem: Trezor Suite and MetaMask use WebUSB, which requires device
resets and continuous re-enumeration that break under Qubes USBIP. Simpler

Hi @tmp.lLDDirZ2Rg , you should post this into Trezor’s github/forums to see if they can integrate this script in trezorctl / Trezor-Suite or standalone utility package in order to have an official solution for us using Qubes.
