Windows 7: USB 3.0 and Bluetooth conflict

Thanks Pooch and Alphanumeric, you have confirmed my suspicions about the drivers. Do you think it could be some sort of IRQ conflict?

I don't know about your laptop but I know on my fathers Acer the built in Bluetooth adapter is actually plugged into a mini USB port on the motherboard. It is accentually plugged into the 4 th USB port. Does your external hard drive have a power pack or is it totally powered by the USB port. If its only power source is the USB port it may not be getting enough juice to run and messing up the USB bus. I've heard that some laptops limit the amount of power to the USB ports to extend battery life. They don't supply the same amount of current as you would get on a desktop PC. I'm guessing your internal Bluetooth adapter is connected to the USB bus and the external hard drive is messing up the USB bus. If you open device manager and look under the USB devices you may see your Bluetooth adapter listed. That would confirm my suspicions if it is.

Actually. I checked already and found that both my BT and WiMax are listed on my Generic USB Hub. And yes the external harddrive is powede only by the USB port. Your post prompted me to modify my power options. I disable the powersave on the USB ports when plugged in. My BT mouse now works although it's very jumpy. I will keep playing with power setting to see if I can improve the mouse performance further. Thanks this was helpful.

USB ports are usually in pairs so if your laptop has 2 ports on one side and one port on the other, the Bluetooth is likely paired with the single port. Try plugging the external drive into one of the two ports that are side by each. It probably won't make any difference but it can't hurt to try it.

I have 2 3.0 ports on the right side and one eSata/2.0 USB on the left side. The problem does occur when I plug the harddrive into either 3.0 port on the right side. Here is another twist. I also have an Express Card with (2) 3.0 USB ports on the left side. If I plug the hard drive into the Express Card I have no perceivable performance issue with the mouse. Therefore, the problem seems to only be between the 2 built in USB ports and the BT radio. Since I can use the express card, this is not an urgent issue but I find it very annoying and don't like being blown off by the tech from Sony. I will try to get a live tech on the phone but doubt they will be more helpful. At least now I can call their bluff on the Ultimate drivers BS.

Thanks again, I will update date this post if I find a solution.

The Express must be supplying more juice to the external hard drive or is isolating it from the USB bus, or both. Thats my guess anyway.

Sorry I didn't read this entire thread but would just like to add that this is complete BS!!! Windows 7 is Windows 7 driver wise - the only difference would be between 32 and 64-bit versions - not whether the version is home, premium, or ultimate.

The tech who told you that either truly didn't know what he was talking about, or just wanted to get you off the phone. I would suggest you call back and speak to a supervisor and file a complaint.

My two cents.

Same problem / different setup

I have a self-built system (Win Ult x64) using Logitech unified BT keyboard and mouse. The BT-dongle is plugged into an USB 2.0 port. Works perfectly - until I plug my card-reader into one of the two USB 3.0 ports. Then the mouse just stops responding. Other USB 2.0 peripherals seems to work just fine together with the keyboard/mouse. Don't really know where to start looking for a solution. Havent checked Logitech for any driver updates yet, maybe a good place to start. Any other suggestions? Rolf

Hi Rolf L, Welcome to seven forums.

First are you sure this is a Logitech unified BT receiver or the Logitech Unifying receiver? The only blue tooth keyboard I found is this one - Logitech - diNovo Edge Keyboard

At any rate these do not require USB 3 ports to operate - a USB 1.0 port is all that's needed. At any rate I would suggest you try moving the dongle to a USB 1 or 2 posrt and see if that fixes your problem.

Also what motherboard/PC/Laptop do you have that has USB 3.0 ports? Can you post a link.

Thanks.

Thanks!

You are of course right - not BT! My fault. But the Unifying receiver for my Logitech K750 keyboard and Performance MX mouse does plug into a USB 2.0 port. Very happy with it.

Motherboard: ASUS P5X58D-E with Intel Core™ i7 Quad Processor i7-950 at 3.06 GHz.

On the P5X58D-E there are two USB 3.0 ports in addition to 4(?) USB 2.0 ports.

I will try a corded set of keyboard/mouse and see if it makes any difference.
