UHK v80, USB connection doesn't wake up After suspend

[mohitt]

My UHK v80 would connect even on USB connection once it has gone past the sleep time. I have to push the reset button the back to get the usb connection to work.

What's your OS?

I've captured this log on Windows 11 with firmware 12.3.5. I connected the UHK 80 to the laptop at 23:49 and woke it up at 10:04. I tried to press the keys to no avail. The display shows disconnected. Replugging USB doesn't work, and "USB device is not recognized" is displayed by Windows eventually. Only resetting the right half fixes the issue.

Note to self: I got the above timestamped log with:

My OS is windows 11 as well, and yes resetting the right is the only way to fix it. Everyday I am resetting the right half like 3-4 times. Everytime I come back from a break pretty much. Because I have set my windows computer to sleep after 30 min of inactivity

[mondalaci]

Assuming it's a regression, would you narrow it down to the exact firmware release that introduces this issue, starting from firmware 12.0.0?

[mohitt]

This is annoying in a day, I have to do this atleast 4-5 times. Now, I tried ble and dongle connection. On BLE and dongle connection my keyboard macros are not typing the keys properly

A $500 keyboard. with so many issues. I have used v1 and v2 both. Both, were great. So, much so. That today I stopped using UHK v80. Since it is so annoying to use.

[mondalaci]

Let me find the problematic firmware version and drill down to the exact commit. It'll probably take a few days.

[mohitt]

Thanks @mondalaci but, why does it drop characters that are supposed to be type as part of the macro in case of Dongle or BLE ?

[mondalaci]

An old bug caused dropped characters, but it was fixed a while back. I can look into it if you share your configuration. Tell me which macro to trigger.
