![]() ![]() ![]() The main files in Microsoft's bluetooth stack, according to System Control Panel's Device Manager entry (now that I've installed the M$ BT stack) are:īthenum.sys = bluetooth bus extender (Microsoft bluetooth enumerator).īthusb.sys = bluetooth miniport driver (USB interface).įsquirt.exe = bluetooth file transfer wizard. I could just cut to the chase and tell you to delete BTKRNL.SYS, but first let me explain how that solution came to me. So what do you do? After struggling with this question for several days and reading other posts, I think I found a brute-force solution. If you can't uninstall the Broadcom enumerator and you reboot, Windows will see the Broadcom enumerator and will keep reinstalling the associated Broadcom bluetooth driver with Enhanced Data Rate II. When you right click on that entry, there is no uninstall option. Unfortunately (if your ThinkPad is anything like mine), the bluetooth enumerator entry cannot be uninstalled. Now uninstall your two Broadcom entries under Bluetooth Radios in System Control Panel's Device Manager, and when you reboot, Windows should autodetect the bluetooth radio hardware and install its own bluetooth stack. I'm not sure what the second "Rev_0399" entry was for, so I didn't include that in the INF file. In my case, I typed:īroadcom bluetooth radio inside ThinkPad= BthUsb, USB\VID_0A5C
