Hi all,
I met a problem when I passthrough the usb device that supports to insert two 3.5 inch hard disks.
I can successfully passthrough the usb device, verified by `lsusb` (the first line "JMicron ...")
	
	
	
		
However, the block device is not listed:
	
	
	
		
I tried stop and restart the vm, tried using both bus-port and vendor: product format. Still the same result. The hard disks is listed by `lsblk` in host when the vm is stopped.
Any inputs are welcome!
PVE version 5.4-3
