Did either of you resolve this?  I am having the same problem now.  Any help would be appreciated.

I have this same issue. It wont let me update my base stations & and THINK its why I cant get both controllers to work at the same time...which mean I cant play games...

I had the same problem and was able to fix it by installing a [PCI-E USB card](https://www.amazon.co.uk/gp/product/B07MZ3Q5KQ/) I found on Amazon. It seems like everyone who has this problem fixes it by doing something to their USB setup (see [this thread](https://www.reddit.com/r/ValveIndex/comments/ds3wpb/valve_index_and_bluetooth_problems/)). Likely the Bluetooth system in the headset doesn't communicate properly with the computer for certain USB ports with certain chips. Pretty sloppy of Valve not to fix this problem if you ask me.

I've initiated update today and after got this error. Base stations/bluetooth. 
Restart didn't fix. Can't find drivers in steamvr to install/uninstall.

Bluetooth capability not detected.
