UHK80 with Windows is in disconnected state after waking up from sleep

[n0rbertg]

Hi,

Keyboard: UHK 80
FW version: 12.1.0
Connected via USB
OS: Windows11

When Windows wakes up from sleep the keyboard is in a disconnected state. After reconnecting the USB cable, it works again.

Sorry, wrong repo, please delete from here.

Should I reopen and transfer this issue to the firmware repo?

Should I reopen and transfer this issue to the firmware repo?

Only if it's not redundant (I've seen similar issues there, if any covers this, then please just delete)

@kareltucek I leave it up to you whether to reopen and transfer this issue.

[kareltucek]

Please do. So far we have a forum thread and (closed!) agent ticket. Not ideal.

Yes, I was the one posted in the forum and have the same issue.

Here are some additional details from testing (with Windows):

Zephyr shell:

# put it to sleep
uhk80:right$ L2 Suspend
 === set transport null
L0 ON
L state 0
L0 ON
L2 Suspend
L0 ON
L state 0
L0 ON
L2 Suspend

#wake it using power button
uhk80:right$ L0 ON
L state 0
L0 ON
L2 Suspend
L0 ON

Generally, the state reporting is pretty quirky.

@benedekkupper would you look into it please? Maybe it makes sense to do together with #1021 (I will follow up shortly on what is needed.).
