I think you have not installed a driver for the device[s] in question.
The SMS/MMS one is probably your mobile phone. I used to see that entry with a previous phone of mine. Many mobile phone makers supply a Windows driver so check their support site for one.
For the others, see my ditty - search for drivers by HardwareID - TenForums

I installed the driver for my phone and that didnt fix the problem but then
Removing this blue tooth device fixed the problem.

So you've [physically?] removed your Bluetooth adapter. If you never want to use Bluetooth then fine.
All the best,
