Dear all,
 
We are detecting
several issues with USB port virtualization with
the Xen hypervisor.
- We cannot do PCI passthrough of the PCI usb bus on a Windows 10 1607 64-bit virtual machine.
The bad result is a Windows blue screen.
- When we use the passthrough functionality on a Windows 21H2 virtual machine, we notice that
the speed of the USB port is not high speed but full speed on a USB 3.0 port
- We notice instabilities when using the nec-usb-xhci driver,  USB 2.0 keys are not recognized by the Windows virtual machine (incorrect descriptor)
 
We
need
your help to find a solution for these problems.
 
The Software used are :
-       
Debian 11 version
5.10.0-20
-       
Xen version
4.14
-       
Windows 10 1607 and 21H2 for virtual machines. Virtual Machine HVM
 
Thanks in advance for your help.
