There are only two pass-through changes:
commit bfe44898848614cfcb3a269bc965afbe1f0f331c
commit 65f14ab98da1da920f98ee8734dc1588b01d6b2b
Can you check whenever reverting the one or the other or both restores
4.0 behavior?
Can you add "lsusb -v" output for the device in question to the bug?

Title:
K800 keyboard no longer works when attached to a VM
Status in QEMU:
New
Bug description:
I use Logitech K800 keyboard which is connected to a PC through
Logitech unifying receiver. In order to control my windows VM i attach
unifying receiver USB device to a VM using "virsh attach-device VM-
Name ./device.xml". Device ID as seen in lsusb is 046d:c52b.
As of v4.1.0 keyboard no longer works when attached to a windows VM.
When attached receiver is still at least partially functional.
Logitech pairing utility properly displays paired keyboard, pressing
buttons on the keyboard shows changing indicator icon in pairing
utility. Pairing and unpairing works. Pressing keys however fails to
register any key presses.
Downgrading to v4.0.0 fixes the issue.
device.xml used to attach USB device:
```
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x046d'/>
<product id='0xc52b'/>
</source>
</hostdev>
```
