Hi, i have a virtual computer with an arm 64 router. In version 8.2.7 the modem connected via USB worked fine. After the update the router stopped seeing the USB modem. The hardware remains unchanged

You can modify the bus number of this xhci to 0 and use an available addr.

'xhci' => { bus => 0,addr => 17 }         /usr/share/perl5/PVE/QemuServer/PCI.pm

having made changes in the PCI.pm file, the following message appears when trying to start the virtual machine

kvm: -device qemu-xhci,p2=15,p3=15,id=xhci,bus=pcie.0,addr=0x1: PCI: slot 1 function 0 not available for qemu-xhci, in use by usb-ehci,id=ehci
TASK ERROR: start failed: QEMU exited with code 1

Use addr=17 or other free

thanks, I have selected the following values and everything works

'xhci' => { bus => 0, addr => 30 }
