Logitech G7 Gaming Mouse jerky jumpy blah

So I picked up a logitech g7 gaming mouse last night to replace my now broken mx1000, which I loved to death.

plugged it in, let the batteries charge, and voila! a jumpy mouse.

never had this problem before, but the mouse will occasionally hiccup, and seem to jump or jerk a bit while i am using it. can't seem to track down the problem at the moment.

has anyone else had a similar problem with their mice?

the mx1000 worked perfect for me, so i am not sure what it is that could be different....

Just wanted to post an update. The G7 mouse uses a usb dongle plugged into the spare battery charger. if the spare battery is being charged on turbo mode, it draws more power than usual from the usb bus, and will cause the occasional jerky movement.

tried plugging the usb dongle into another port, no more problem!

great mouse, btw. silky smoooooth!

okay, I have since returned my original purchase, and replaced it with another g7 after having problems.

still jerky. and I am having a hell of a time tracking it down. I can't really seem to pinpoint why the problem is occuring.

I plugged back in my old mx1000, and there were no problems.

I moved the receiver nearer, farther, unplugged all the cordless phones i the house, charged batteries and swapped them out, didn't have one charging while I was using it, had one charging while I was using it.

this is getting frustrating, and I am hoping that either someone else has this problem (i am not insane), or even better, someone might have some suggestions for a possible solution.

I have tried:

1. Fresh batteries.
2. Different USB port for the receiver
3. Unplugged, moved away anything that might also be causing interference
4. praying to the usbhid gods for assistance

everything is coming up a dud. I think I may even go and buy the g5 version of this mouse (the corded one), and see if the problem persists. If it does, at least i know its not the radio receiver.

any ideas on how best to tackle this problem?

ubuntu 5.10
Xorg 6.8.2

Section "InputDevice"
        Identifier  "mouse0"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/input/mice"
        Option          "Name" "Logitech G7"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"
Any ideas at all would be welcome to track this thing down!
