I have found Windows USB drivers for BB Android devices at the link below but I am not sure if it is the last version available:

Thanks. For the record, here is the size and checksum of USB drivers v 5.0.0.3:

I have also found another download link, shown below, just in case:

I have installed Mobile Upgrade Tool ver. Q 5.1.8, just to have a look how it works. It is TCL's OS update utility for BB KEYone discussed here:

According to User Manual (which can be found in tool\user_manual directory) BB USB drivers are bundled in the installation package. In my case, the drivers had already been installed before (v5.0.0.3) and Mobile Upgrade Tool's installer "repaired" them:

I suspect that the drivers version was downgraded. Here are INF files:

My suspicions about USB drivers downgrade by the "repair" process proved unfounded. The four drivers listed in the post above remain intact and the "repair" only affects some 200 Windows registry keys and another 100 or so files in the following directory:
