USB Speaker & USB Bluetooth Adapter Not Working

hi there,

my USB external speaker and USB bluetooth adapter (for my plantronics headset) is not working. I believe this had to do me removing a critical program (from add/remove programs) about half a year ago - i can no longer do a system recovery to retrieve the program. I'm currently operating on windows 7x64-bit. all drivers are up to date and working. the usb drives work fine - i've tried testing each slot by connecting my external mouse and all seems functional. it's only when i plug in the external speaker or usb bluetooth adapter that things go wrong - see screen shots below. my internal speaker and internal mic work perfectly fine. it appears to be only an issue with usb audio-related devices. these devices work with other systems and computers, so i know that it is not the device itself. i've tried uninstalling and reinstalling conexant audio, but that did not work. i've gone into the device manager and all looks ok there. i've disabled and renabled, updated all drivers, and still nothing....any help would be much appreciated.

Laptop: Lenovo T410s

thanks so much for any help or guidance you can provide.

Connect the devices, one at a time. Then go to the Device Manager and display the USB section. There will probably be an Unknown device shown. If there is, RIGHT click on the entry to highlight it and then LEFT click "Uninstall" (do not uninstall any drivers). Disconnect the device from the PC after the Uninstall. Then do the same thing for the other USB device. Restart the PC and then connect one of the devices and Windows should detect it as "new hardware" and install it. If not, run sfc /scannow (run it 3 times) and see if it finds any problem from whatever you may have deleted.

Sorry it took so long to get back to you. I've been out on a project.

It looks like your Plantronics BT300 is recognized. If this is the headset device, Uninstall it, physically disconnect it from the PC. Restart the PC and after the Windows starts it will be detected and reinstalled.

However, your comment about removing a critical program concerns me and it could very well be the key to everything working. Not knowing what that was, I can't really say if it is the problem.
