I run Qubes 4.1 on Thinkpad T490.
It is connected to Lenovo docking station over USB-C.
Keyboard and mouse are connected to docking station’s USB ports. Qubes policies are configured to always allow both devices to dom0.
after initial boot everything works fine like expected.
But after the system goes and comes back from suspend (without being physically undocked) both devices never get their keyboard/mouse functions back again (but both of them are still “visible” usb devices as before). Reconnecting them to docking station doesn’t help either.
