I've probably missed the boat on this one, apologies for necroposting, will be sure to sage etc.

This sounds like an issue with the Bluetooth Stack or possibly a very badly behaved driver. (I'm assuming here that the lock-up only happens during the 1-3 seconds that the device is waking up, if so there's potentially some idiotic while loop blocking all other I/O, although given the number of different busses involved I still find that .... weird to say the least).

On linux you can use lp2ping. I'm not sure if there's a windows port, but you might get it to run under WSL if you're using Windows 10. You might also want to dig out the technical specification document for your keyboard and see if there's a vendor specific HCI command for setting its sleep timeout or what have you.
