2 questions. USB mouse issues, and Bluetooth adapter question.

Okay I have 2 quick questions the first one might be a bit difficult to answer but hopefully with a little help I can get to the bottom of this.

1. I have a Dell XPS L702X. I got it about a year ago and it has given me absolutely no trouble. I simply love the machine! However...there is only one issue. When I use one of those wireless mice with a dongle they ALWAYS skip around/lag/stop working for a second. I'll describe it in full but let me first tell you that I've covered most of the bases.
-other USB devices work fine. Such as external hard drives, Ipod Sync cables, fans, etc.
-I've tried it both with the Official logitech software installed, and without.
-I've tried multiple wireless mice, all result in the same effect
-I've tried them on other systems and they work fine.

Now if I was to describe what it looks like...well. If I was to hold my left click down and draw in paint, it would be fine, but every 15 or so seconds it might randomly just stop moving completely, when it does start to work again it sort of jolts across the screen. This is INCREDIBLY frustrating when playing any games, or especially when photo/video editing which are the main uses of this machine.

I thought maybe there was some software out there that can test connectivity of a USB device to ensure it has a constant connection, but any other thoughts of course are welcome!

2. Lastly, I'm guessing the answer to this question is yes. but I wanted to know exactly how important the quality of a bluetooth dongle is in terms of audio quality. I primarily use a cheap $3 bluetooth dongle I got from one of those chinese manufacturers on ebay, and it does work fine. Although when I'm speaking with my friends on skype they say that every now and then it crackles, and if I play my voice back to myself I sound kind of muffled and just all around bad. I'm using a Turtle Beach Earforce Delta. It's a $300 headset so I'm hoping the quality could be better if I upgrade the dongle to say something like: http://www.newegg.com/Product/Product.aspx?Item=N82E16812146022 but at the same time I don't want to waste my money if it won't do anything.

finished. I also want to add about the mouse issue that I also tried enabling and disabling nearly every single feature/option in the logitech software. such as letting the OS attain settings, and such.

Hi,

I would suggest you to connect this Bluetooth Dongle with another computer and then check the functionality of the Bluetooth connection and wireless connection. If the connection is good then I would suggest you to uninstall and reinstall the drivers of the original computer. However, if the connection is bad (same like the original computer) then I would suggest you updating Bluetooth dongle.

Hope this helps
