Hi All On XEN-4.16 with Ubuntu 22.04 Dom0 and HVM-DomU, I tried to do a USB mass storage device passthrough to DomU. I followed the PVUSB method mentioned in https://wiki.xenproject.org/wiki/Xen_USB_Passthrough.
I am able to do passthrough for USB 2.0 and 3.x version 32/64 GB mass storage devices to DomU. Passthrough failed for "SanDisk 250GB SSD USB-C, USB 3.1" with below error. Able to access the SSD in Dom0. Can someone help with what could be missing here. *Commands used:* host$ sudo xl usbctrl-attach vm1 version=3 ports=6 host$ sudo xl usbdev-attach vm1 hostbus=3 hostaddr=2 *Error Log in DomU* VM1:~$ sudo dmesg [ 152.841566] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd [ 152.867164] usb 2-1: New USB device found, idVendor=0781, idProduct=558c, bcdDevice=10.12 [ 152.867173] usb 2-1: New USB device strings: Mfr=2, Product=3, SerialNumber=1 [ 152.867177] usb 2-1: Product: Extreme SSD [ 152.867179] usb 2-1: Manufacturer: SanDisk [ 152.867182] usb 2-1: SerialNumber: 31393430475A343030363932 [ 152.899103] *usb 2-1: USB controller 0000:00:04.0 does not support streams, which are required by the UAS driver.* [ 152.899110] usb 2-1: Please try an other USB controller if you wish to use UAS.
