Avago ADNS-9800 jittery

post #1 of 6
Thread Starter 
So I have a brand new mouse (brand doesn't matter, its all about the sensor, I bought the mouse I did for the way it fit my hand, and proper Linux support, if you must know Roccat Kone PURE color, in orange - which matches my keyboard biggrin.gif)
I purchased this mouse to replace my Razer Naga Epic (worst mouse I've ever owned) which was purchased to replace my A4tech X750f (BH) which was probably the best mouse I owned.

I use a Steelseries Experience I-2, which is a glass mousepad. The ADNS-9800 has NO issues tracking on this mousepad at all, but periodically, when I bring the mouse to a stop... it jitters around in a 1-2cm circle. If I apply any pressure to the mouse at all, or the mousepad - the jittering stops. No movement, just pressure. It seems like its picking up arbitrary environmental vibrations, but I don't know how to stop this from occuring. Its not a deal breaker as it tracks fine when in use, but jitters at a stop with both hands on the keyboard, and only occasionally.

I've played with the settings quite a bit, and disabled the TCU/DCU features of this mouse entirely, but the issue persists. The optics even get a nice clear picture of the glass surface:


Has anyone else had similar issues?
Is my mouse potentially defective?
Should I ditch the glass pad (I would hate this as its the most comfortable surface for me) for another hard pad alternative?
Anyways, thanks in advance.

If you ask me, the ADNS-9800 is a defect in itself. But anyway, I had a Kone Pure (non-color) too for a while. Try lowering the resolution and report rate significantly (you can raise them again later) to see if that helps. As for hard pads, the mouse worked just fine on my old Func Surface 1080.

I dunno, I find mine to be perfect.

Don't listen to the 9800 naysayers. Unless you're into low sens FPS gaming, the 9800 is one of the most precise sensors. Jitter can occur at high dpi on rough cloth surfaces such as QcK or Goliathus control. I couldn't get my Taipan to jitter though.
Did you try another surface to see if it still jitters?

If it is because if vibration: put some buffer under your mousepad? Maybe a spare clothpad (if you have one)

Also isn't glass known to cause tracking issues in general? I know VCSEL Sensors rose because of their higher surface compatibility, but afaik glass is still problematic, isn't it?

I keep my Steelseries Experience on top of a Razer Goliathus extended (I like the way it cushions my wrist if I decide to relax my hand, and it looks good.) It's a pretty specifically engineered glass mousepad - it has a different somewhat frosted looking surface with a solid color backing to it. Mine is black in appearance. I'll try playing with surfaces and see if that is the issue, if it is - I may be able to contact Avago/Roccat to push a new firmware update to resolve the issue (which is very likely possible.) If its vibration, it should still be addressed since the only vibration I have is by extension to the 120mm fans in my case. My speakers are all on isolating pads and my subwoofer is always on low volume due to neighbors.
