[Bug 1846451] [NEW] K800 keyboard no longer works when attached to a VM

[Bug 1846451] [NEW] K800 keyboard no longer works when attached to a VM

[Rokas Kupstys]

Public bug reported:

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>

```

** Affects: qemu
     Importance: Undecided
         Status: New

** Attachment added: "VM xml"

[Gerd Hoffmann]

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?

qemu: -device usb-host,...,guest-resets-all=true

libvirt:

   <qemu:arg value='-set'/>
   <qemu:arg value='device.hostdev0.guest-resets-all=true'/>

... assuming this is is the only pass-through device.

If you pass through more devices you''l have hostdev0, hostdev1, ... and
have to pick the correct one.

[Rokas Kupstys]

I am bit slow to test, but i just realized that i am still not sure how
to test this. My devices are attached using "virsh attach" after system
has started. So it seems to me there is no way to test it with libvirt.
A global option to restore old behavior would be useful until libvirt
starts supporting this option.

Any way to get old behavior back when using `virsh attach` command?
Devices are not attached on boot. I am stuck with qemu 4.0 because of
this.

Try this:

   <qemu:arg value='usb-host.guest-resets-all=true'/>

Not fully sure this works for hotplugged devices though.

  register any key presses.

  Downgrading to v4.0.0 fixes the issue.

Title:
  K800 keyboard no longer works when attached to a VM

Status in QEMU:
  Fix Released

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'>

                  <product id='0xc52b'/>

  </hostdev>
