This has been happening for me ever since I got the Kemper years ago, never found a solution. Mine seems to be when my Mac goes to sleep.
Yes! i forgot to mention that could be a possibility too. Ive noticed it happening when i "wake up" my PC after ive been away doing something. Well at least i know im not alone and i dont need to buy that new USB cable
Kind of makes sense thats why it would happen and the connection could be broken but a bit of a nuisance to keep unplugging the USB cable and replugging it back in everytime the computer has a nap not to mention possible damage to the USB connection and cable over time having to constantly do this.
Surely there is a way to not have this happen.
