Emulator

Game Name?
The Dolphin Emulator itself, happens in all games.

Game ID?
N/A

What's the problem? Describe what went wrong in few words.
As soon as Dolphin opens my mouse driver begins to lag and disconnect constantly, even if the mouse is inactive. This issue happens even when Dolphin isn't emulating and gets worse if I start emulation. The issue causes constant stuttering and freezes in all games when emulating (Most likely from windows re-connecting the driver). Only "fix" is to disconnect the mouse or switch to a default Microsoft mouse before Dolphin starts, reconnecting the mouse after Dolphin launches still causes the issue. Closing Dolphin without a mouse connected will cause it to crash (may be unrelated to this issue).

What did you expect to happen instead?
For the mouse driver to not constantly disconnect, forcing windows to re-connect it while freezing emulation.

What steps will reproduce the problem?
1.Start Dolphin with mouse connected
2.Cry as mouse disconnects
1a. Start Dolphin without mouse connected
2a. Connect mouse
3a. Mouse disconnects and issues persist

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
Tested on the newest dev build available (4.0-6213 May,8 2015). Been mostly using a slightly earlier version (4.0-6153). Issue in both versions.

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Latest stable version doesn't have this issue (4.0.2) but I can't find an earlier dev build which doesn't have this issue.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Running Windows 7 x64 (Home Premium). GPU: GTX 660 CPU: 5200-FX (AMD) Mouse: UTechSmart 8000 and Microsoft BlueTooth Mouse (Both USB) -- UTech mouse disconnects, Microsoft mouse works fine

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
No settings within Dolphin seem to resolve the issue, disabling mouse software didn't resolve the issue either.
