The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state
back to "New" within the next 60 days, otherwise this report will be marked as
"Expired". Or mark it as "Fix Released" if the problem has been solved with a
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
isochronous usb device forwarding with windows 10 and xhci freezes
Status in QEMU:
Incomplete
Bug description:
When I try to forward isochronous usb devices (webcam, HID-Audio) via
usbredir into the VM, the devices work for a few minutes then the device stops
working and stays that way until a VM reboot or a windows driver reload.
It does not matter if I use qemu-xhci or nec-xhci.
I can gather more information, if its helpful!
