Qubes 3.2 Error when Re-Installing of Qubes Windows Tools 3.2.2.3

[PhR]

Hello,

on my Windows 7 HVM USB devices could not be recognized when beeing
attached via sys-usb.

Therof I uninstalled Qubes Windows Tools and tried to reinstall after a
reboot.

Strangely installation is now failing with an error:

"installer has encountered an unexpected Error installing this package.
... The Error code is 2753"

Any suggestion what is wrong and where to troubleshoot the problem?


kind regards

I'm 99% sure you can't attach single usb devices to windows vms. Only entire pci controllers can be attached via qvm-pci

Thank you for the hint, I have examined the USB-Controller-Layout of my
Lenovo X230 and came to the conclusion to pass USB 3.0 Controller to my
Windows HVM as I will only loose 2 out of 3 USB-Ports to my Windows
AppVM and my internal LTE-Card which is also connected to the same
PCI-Controller.

After adding the PCI-Controller to my Windows HVM I had to set
pci_strictreset false to be able to boot into windows.

When looking under devices, the controller is not listed as USB controller.
Instead I see two entries with a yellow warning sign under "Other devices":

- Universal Serial Bus (USB) Controller
- XP001 XENBUS VBD

Any idea what is missing to get USB support in my Win7 HVM?

You need to install the USB 3.0 driver within the Windows VM.
