Dear All,

We send you a message few days ago.

We have major performance with XEN USB Drivers. We use your driver to load data in a device and we need USB3 High Speed USB protocole

Do you have a new issue of the HCI and NEC USB Xen Driver ?

We hope you will contact us quickly.

Best regards

Objet : Need help on USB port virtualization with Xen hypervisor
Critère de diffusion : Confidentiel

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.

Best regards,
