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.
