    USB Bluetooth Adapter's Blue Light IS LIT When Bluetooth Is OFF?


    Hello.

    I have an issue with my Medialink USB Bluetooth Adapter - Version 4.0 Class 2 Smart Ready Adapter (Model No. MUA-BA3). Let me explain...

    Okay, I have setup my Medialink USB Bluetooth Adapter with the drivers for my Windows 7 operating system. Now, when I plug this USB Bluetooth adapter into my USB port connector on my desktop computer, it automatically lights up with a blue light on the Medialink USB Bluetooth Adapter itself and on my Windows 7 system tray/notification area I get the Bluetooth icon displayed as “ON”. Then I go ahead and pair the computer and my device(s) (example: a Smartphone) to connect which they do successfully. When I am done using the Bluetooth technology, I disconnect the Bluetooth connection from each device and then instead of leaving your USB Bluetooth adapter ON with my Windows 7 operating system, I go into my Windows 7 system tray/notification area and select “Turn Adapter OFF”. I then get the red Bluetooth icon in my Windows 7 system tray/notification area demonstrating that my Bluetooth is indeed OFF and the Bluetooth blue light on the Medialink USB Bluetooth Adapter goes OFF or is not lit any longer. Okay, so far so good – everything is normal.

    However, when I shutdown my Windows 7 operating system and then restart the computer at some later point, I notice that the Medialink USB Bluetooth Adapter still shows on my Windows 7 system tray/notification area as OFF (okay – normal); BUT THE BLUE LIGHT ON THE MEDIA LINK USB BLUETOOTH ADAPTER IS NOW “ON”! The only way I can turn off the blue light on the USB Bluetooth adapter is to manually go through the Windows 7 system tray/notification area, turn ON the Bluetooth technology and then promptly turn back OFF the Bluetooth technology in order for the Medialink USB Bluetooth Adapter’s blue light to go OFF again. I find this to be a real pain and chore each time to have to go through these manual steps to turn OFF that Medialink USB Bluetooth Adapter’s blue light when the Medialink USB Bluetooth Adapter’s blue light SHOULD BE OFF TO BEGIN WITH!

    I would assume after the system (re-)start and leaving the Medialink USB Bluetooth Adapter plugged into the USB port connector on my desktop computer, if the Bluetooth technology is indeed OFF as set with the Windows 7 operating system settings, then the Medialink USB Bluetooth Adapter’s blue light should be OFF as well, BUT IT IS NOT. I have no intention of consistently plugging in and out the Medialink USB Bluetooth Adapter when I plan on using it or not; but instead leaving the Medialink USB Bluetooth Adapter always plugged into the my USB port connector on my desktop computer at all times and using the Windows 7 system tray/notification area’s Bluetooth icon to turn ON and OFF the Bluetooth technology when needed.

    I have contacted Medialink/Mediabridge and they have informed me the rationale for this issue: "The only reason the light would be lit is if the bus power from that USB port was running. I [they] looked for ways to manage the bus power settings of the USB host but was unable to find anywhere in the Control Panel that would allow you to adjust that particular setting." Makes perfect sense to me that the bus power for the USB port is ALWAYS RUNNING and the computer starts, the USB ports are powered and therefore the Medialink USB Bluetooth Adapter is always lit at system start until I turn off the Medialink USB Bluetooth Adapter via Window 7's system tray/notification area. Specifically, the Medialink USB Bluetooth Adapter is connected to one of the USB ports on the front of my desktop computer. The front desktop USB port connects to one of the USB pin connectors on my ASUS P5Q motherboard. Further, I have an OLDER ASUS P5Q motherboard that does NOT support Bluetooth as part of its BIOS settings -- PRE-Bluetooth capability. Therefore I installed the software on my Windows 7 Professional 64-bit and drivers that came with my Medialink USB Bluetooth Adapter. Medialink/Mediabridge has informed me they have no solutions on their end and I am the ONLY user experiencing this issue -- honestly, hard for me to believe the latter! They have tested this issue on a SONY VAIO laptop with Windows 7 and for them, the indicate they "have found that the light on the adapter stayed OFF after rebooting the machine." If you are thinking of me using the MSCONFIG and uncheck the startup for this Medialink USB Bluetooth Adapter, again; this will NOT turn off the light on the Medialink USB Bluetooth Adapter dongle. This ONLY disables the startup of the program/driver.

    Since, I have considered of a possible solution. If I can get say, Windows Task Manager setup with a task that would: (1) turn ON the Medialink USB Bluetooth Adapter program at say 30 seconds after the desktop finish loading and then, (2) turn OFF the Medialink USB Bluetooth Adapter program at say another 30 seconds after that. This would be all automated from within Windows 7 and definitely turn OFF the Medialink USB Bluetooth Adapter dongle light every time shortly after startup.

    Please answer:

    1. What is your thoughts of my possible solution?

    2. Could you please give me some detailed steps I would need to do in order to setup with Windows Task Manager, especially settings for "Trigger" and "Actions" sections of the Windows Task Manager?

    3. Do you have another solution yourself for my issue?

    Please reply.

    Thank you!

    Hi, can you give a 20 word or less problem summary please, I got lost in those wordy details.

    I am no BT expert or anything, but all I read was complaining about a light being on, which a piece of black electrical tape fixes around my house, regularly *cough* fire alarms.

    If the maker of the device doesn't have a solve to your issue... that is usually the end of the road with a cliff.

    What a bunch of lazy... anyway, I'll tell you my thoughts.

    I'd make a batch script to disable and one to enable that particular device as if you were doing it from Device Manager. So that in the end you will have two links/icons on your desktop to enable and disable a particular device. And add a scheduled task at logon to run the "disable bluetooth" script again in case the device doesn't stay disabled on reboot.

    Thankfully MS made a Device Manager-like program that works by command line that is available for free here.

    If you are interested (tell me) I'll give a shot at writing a more coherent tutorial for this, but feel free to experiment with it yourself (at your own risk, mind me, this isn't a toy).

    Act more like a pro man , this is a techsupport forum...

    Although you do have a point. That's a desktop, so who cares for bluetooth anyway?

    Laziness kicks in on TL|DR, I did inform user because this had many views and not even one comment is general a sign of TL|DR and if you don't inform people to summarize, they will keep getting no help often and frustrated.

    I'm glad you knew about the issue, though questionable if there really is one.

    Sense of humor intact!

    @ bobafetthotmail:

    Hello. Thank you for your insightful response!

    Okay, now I need to make a batch script as you have stated. I am sure your answer will work. Last time I made a *.BAT file was some time ago for some automated process. I have to refresh and re-educate myself again with them. I will use your "batch file" hyperlink in your comment as my guide. It will take me a few days to research this and begin script testing for a solution.

    I am sure I am not the only user that is experiencing this with Bluetooth adapters/dongles, as I am sure there are many users out there that have had the same issue. Many users may not care about their Bluetooth adapter/dongle lit when it was actually OFF... ...and/or their motherboard is a PRE-Bluetooth compatible version and therefore they have no way to set the Bluetooth option through their BIOS. But if they had a solution to this issue, they just may follow that solution.

    Please give me a few days to look into this.

    Yes, if you wish, please make a tutorial for this; that would be great not only to me, but other users as well experiencing this same issue. That would be most grateful!

    Again, thank you for your help!
