bluetooth peripheral device - drivers not installed W7x64 USB 4.0

[mwhaynes]

I recently installed a Kinivo BTD-400 usb bluetooth adapter so I could transfer files from my Samsung Galaxy s2 I727 phone. I downloaded the current installation files from the Broadcom site. At the end of installation, a message box lists several items "ready to use" (AV source, headset, etc) but three items saying driver not installed.
I have new entries in device manager

• Bluetooth Radios - Broadcom USB device and Microsoft enumerator
• Network Adapters - BT device personal area network and RFCOMM protocol
• Other devices - Bluetooth Peripheral Device entries with exclamation marks.

I added my phone shows to Bluetooth Devices but it appears with an exclamation mark. I right click, troubleshoot, apply fix. Driver for bluetooth peripheral not installed. Try again. Same result. When I select a picture and click "share via Bluetooth" I get a message "image not sent." So my phone and computer see each other, but I can't seem to send a picture. Please help!

Hi, to upgrade W7 BlueTooth, you must know the brand of the BT chip, and download from this one. Your problem seems to be missing the a2dp protocol, you get the exclamation mark. If your BT chip is not Broadcom, then drivers fail.
