Comment 48 for bug 123920

I've just spent a little more time trying to work out what the issue is. I had a pretty loaded machine a couple of days ago.

I've booted up. I have two mice attached to the machine, one dinovo the other a usb mouse. The usb mouse works fine and fast. The dinovo mouse exhibits the following:

1. if I move the mouse very, very slowly then the mouse moves in an expected fashion.

2. if I speed up the movement of the mouse it begins to judder. It moves smoothly for a couple of millimeters, pauses then jumps a couple of millimeters, as though the bluetooth streaming is slow and ubuntu is always playing catch-up.

When I'm just using ubuntu normally, this is not an issue. When I'm using netbeans and the mouse movements go though a fair amount of additional processing, then the juddering steps up another level and, as I posted above, I keep on having to compensate for the mouse position. I've actually just noticed it again, here, whilst writing this. If I move the mouse to edit another part of this port, more likely than not, as I'm about to click the right button with the mouse stationary it will jump past the correct position and I will then have to move the mouse back a fraction.

The dinovo dongle is less than half a meter from the mouse.

When I used the dinovo in previous versions of ubuntu I was never aware/conscious of this behaviour.

Using the usb mouse gives no such problems.

Once again, a thousand thanks for getting dinovo to work.

Cheers
