Still an issue as of QEMU 6.0.0rc2.
I can't (still) exclude that it's an issue on the host side, although,
when it comes to USB passthrough, I don't have issues with similar
devices (mice, keyboards etc.).
The module blacklist workaround works.

ok, so, if I understand correctly, the workaround is:
- set `x-no-kvm-intx=on` and enable MSI in the guest (via regedit or
module params)
which may lead to a performance regression (at least under certain
circumstances).
Is it therefore preferrable, performance and configuration-wise, to use

Public bug reported:
The commit b2fc91db84470a78f8e93f5b5f913c17188792c8 seemingly introduced
a regression on my system.
When I start QEMU, the guest and the host hang (I need a hard reset to

Public bug reported:
I can't properly passthrough my Xbox One controller to a virtual
machine; it causes USB disconnections on the host, ultimately preventing

I've seen a few other cases reported in other websites, which show the
same symptoms:
