My desktop computer doesn't have innate bluetooth capability. SO I put a bluetooth dongle there.

It works.

I can listen to bluetooth headset with it.

However, the mic doesn't work.

I think it has csr 4.0 written on it.

I want to know the exact type of bluetooth dongle. Is there a software to do so?

I tried belarc advisor but it doesn't show anything.

  • Looks like you didn't attempt to Google "csr 4.0" From the endless links on the first page, this seems to have a fair amount of information about it: dx.com/p/…. – fixer1234 Jun 16 '16 at 5:08
  • @fixer1234 Your link is 404 :/ – DavidPostill Jun 16 '16 at 9:05
  • @DavidPostill, Thanks. The link must have gotten corrupted: dx.com/p/… – fixer1234 Jun 16 '16 at 17:33
