Raspberry pi 4b USB passthrough

[botardo]

Hi,

trying to passthrough USB3 to debian VM but no luck yet. USB 2 works ok, I can see hard drive in VM, but when I connect it to USB 3, nothing.

I installed proxmox from ISO, running UEFI from SD card. Installed proxmox to 60 gb usb hard drive. Everything boots ok. I can see both drives in proxmox

When I try to attach USB to VM, for some reason USB3 option is grayed out

When I start the VM, USB is present by typing lsusb command. lsblk is not showing any drives except the boot drive for the VM.

I have limited knowledge, but I would like to understand what is the problem here.

Which kernel do you use ?

Can you share command pveversion --verbose and lsusb -t (on you vm and host).

The strange thing about lsusb is that I do not have that command on the host and don't know how to install it

@jiangcuo At the current "port" Repository Version. My Raspberry PI 4 (Installation via Repo) can't start VM's with mounted USB. How can I use the published fix in jiangcuo/qemu-server?

Error Message: kvm: -device qemu-xhci,p2=15,p3=15,id=xhci,bus=pcie.1,addr=0x1b: Bus 'pcie.1' not found TASK ERROR: start failed: QEMU exited with code 1

[Rappelkiste98]

I build the qemu-server from your Git Repo, on the Raspberry. Now the VM runs without Problems. Is there a Plan to Publish this Hotfix to the Default "port" Repository?

@Rappelkiste98 Can you share steps to recompile qemu server
