Help diagnose faulty USB (maybe)

post #1 of 3
Thread Starter 
Ok either my USB on my mobo is bad, or its my gpu.
asus sabertooth z77
i5
16gb ram
gtx660ti
microsoft sculpt ergo wireless mouse/key
windows 7

PROBLEM:
mouse cursor gets SUPER choppy, like jumpy skipping around non responsive every moment or so.
sometimes its fine, sometimes its so bad the computer is unusable.

mobo bios has latest flash
i've updated my usb 3.0 drivers

I also have a usb wireless adapter which goes on/off and gets really bad download speeds, like 2-9mbs max on a 200mb connection.

also during the win7 install I had to dissable my HID device in device manager or else the install would crash every time..
I just re enabeled it after install and moved on.

QUESTION:
is there any way to test the USB hub itself, or the uSB ports, or the drivers, to make sure if they are functioning properly?

Try a wired mouse maybe?

I've had my fair share of wireless mouse that would do this because I was either too far away from it or the wireless receiver and wireless mouse were both cheap and low quality.

How many bars (signal at bottom right of the taskbar) does your wireless USB adapter get? and how fast is your internet? 2-9 megabits download?

my wireless usb internet adapter gets exactly what you said.
2-9mbps when i test it.
and i get full bars almost always.
it's a REALLY cheap adapter though.
doesn't get dual channel or 5mhz which is lame because the rest of my house gets dual 170mb down, haha.
I don't mind though as long as its reliable.

the mouse is the issue..

oh ALSO a big issue is that I can never install windows with my mouse plugged in.
it will always bluescreen with a HID error.
but when I unplug the mouse it installs smoothly.
