I purchased an Excelvan branded Bluetooth USB dongle recently in hopes that I could get my Bluetooth headsets working with this computer. The package indicates that it supports Windows 7, and my system is running Windows 7 64 bit.
When I plugged it in to a USB port, the device installed, and in the device manager under Bluetooth Radios, Both "Generic Bluetooth Radio" and "Microsoft Bluetooth Enumerator" show up. Neither of these has any errors appearing. In addition, there are 4 new entries in the "Other devices" category, all marked as "Bluetooth Peripheral Device". They do have errors indicating that there are no drivers installed for these 4 items.
I have 3 separate Bluetooth devices (a generic headset, an Emerson headset, and a generic Bluetooth speaker) that all function with other computers (both Windows 7 and 10, 64 bit) and cell phones with no issues. With the computer I am writing about (using the Excelvan dongle), these devices can be discovered by the computer, and indicate that they are paired. They appear in the devices and printers menu as Bluetooth headset, but they have no sound output. In the playback devices menu under sound properties, none of the devices (the Bluetooth connected headsets) appear at all.
I believe the issue is that Windows 7 does not include a driver for at least part of the hardware. I have updated all my drivers from Windows Update, with no success.
I am including the Hardware ID's from the device manager for the 4 parts of the dongle with no driver, just in case that is helpful:
Any help that anyone can provide would be awesome!
