I just thought it might be useful to provide my experience...
I was trying to get ATTiny88 to work as an inexpensive alternative to Arduino Nano. In this process I got to the point where I installed libusbK device driver on my Lenovo Windows 11 laptop. After giving up on the ATTiny88 a few days later I attempted to use a Bluetooth headset but it wouldn't connect. I attempted to remove it from the Bluetooth interface but that "Failed". I looked the the Windows Device Manager but saw no Bluetooth device listed. What have I done in recent days that may have effected this? I installed libusbK which WAS listed. When I expanded libusbK, I saw Bluetooth listed below it. I uninstalled libusbK and did a search in the Device Manager for new hardware. Suddenly all my previously paired device where listed.
Again, I appreciate the work that went into libusbK but it broke some functionality on my laptop.
