Published by & filed under Misc Software.

I was recently asked to look at a Sony Vaio VPCSB which was detect­ing new hard­ware on every Win­dows boot.  The machine was oth­er­wise work­ing well.  Upon inspec­tion I dis­covered that there were sev­er­al unknown devices which seemed to be related to Bluetooth.  I rein­stalled the latest drivers from the Sony web­site but this failed to clear the unknown devices.  The search was on…

The unknown devices had the hard­ware ID BTHENUM\{6e0c8f4c-d928-4852-b6b2-f0f0e0d126fa}.  Googling quickly made clear that I was not the only per­son hav­ing this prob­lem.  The actu­al hard­ware inside the Sony is lis­ted as a Fox­Conn T77H114-BCM2070.  This is based on the Broad­com (BCM) 2070 chip.  I down­loaded some updated Bluetooth drivers dir­ectly from Broad­com, but as I’d expec­ted they refused to install, stat­ing that no val­id hard­ware was found.  This is because Broad­com basic­ally wont provide drivers dir­ect to end users, so if your OEM has­n’t updated their cus­tom­ised drivers (as Sony haven’t) then you’ve not got many options.

For­tu­nately I found a for­um thread sug­gest­ing that there were some new­er Broad­com drivers avail­able from HP which had­n’t been locked to HP only devices.  I down­loaded these new­er drivers which installed per­fectly first time.  As I’d hoped they included drivers which worked for the unknown devices.  After a quick reboot the laptop booted as expec­ted and no longer star­ted try­ing to loc­ate drivers.  Suc­cess!  Thanks HP.
