Thanks for responding.
The only model number seems to be very unclear on the underside, something like "Microsoft Wireless Middle Mouse 350" Battery is a single AA. Mouse transmit wirelessly into the computer box.

I recently had that happen with a wireless trackball. My problem turned out to be a newly-replaced wireless dual-band router. The old single-band router was no problem. I solved it by using a USB extension cord to move the little receiver dongle closer to the desktop and away from the router. No problems since that. Of course something like a mouse stutter could be any number of things, especially unseen tasks eating clock cycles. |

Of course something like a mouse stutter could be any number of things, especially unseen tasks eating clock cycles. This is also a problem with USB3 ports connected to USB3 cables connected to poorly shielded peripherals. Moving the "USB3 antenna" away from wireless mouse/dongle combo helps. Intel has a report on its web site, about broadband RF from the USB3 cable, smothering 2.4GHz. I can't wait for USB 3.1 to come out, and interfere with even more stuff. This is not a problem with USB2 devices or cabling, as spectrally the RF (if any) is not in the important band. Many wireless HID devices now, run at 2.4GHz. Wifi runs at 2.4GHz. Bluetooth runs at 2.4GHz (frequency hopping). Whereas in the old days, a few HID devices were down in the CB/toy car band (27MHz or so). The USB3 RF is broadband and not narrow band, so it covers quite a range of frequencies. The last USB3 product I bought, had minimal shielding (treated with the same level of concern as a USB2 design would be). But fortunately for me, I have nothing Wifi/Bluetooth/nano_dongle related. All mice here are wired (some PS/2, some USB, and even one serial RS232 mouse running on the test PC right now). Linux doesn't seem to recognize the serial mouse, when I tried it. At least, not automatically like the Windows I tested against. The most likely failure on a LED/laser wired mouse, is the cable eventually breaks where it enters the mouse. My current mouse is "ripe", and I'm just waiting for it to snap. That too will stutter and act up, once the wire breaks. Paul |

Microsoft mouse, in 4 year old pentium system running Windows 7 home premium, has developed an intermittent stutter. Clean it. A tiny little hair or lint piece can flutter across the LED which then the LED interprets as movement of the mouse. Get a flashlight and peer into the LED opening and use a tweezers to remove the crud. Alternatively, open the mouse to clean it thoroughly. Another problem with ancient mice is the stranded wires in the cord will break due to stress. Think about it: you can keep bending a metal plate back and forth and over and over and eventually it breaks. Wires will do the same. The only cure is to open the mouse, cut back on the cord and solder the new exposed wire ends to wherever the old ones went on the PCB inside the mouse. You probably should cut back about 2 inches on the cord to make sure you are away from the flex point in the cord. You can test if the wires are flaky simple by pressing on the mouse to make sure it does not move at all and then flex the cord near the mouse in all directions. Most mice have buttons that are merely a split top half of the shell. The plastic bends when you press to push down on a micro switch. If the mouse is abused (banging on it) or merely from fatigue after years and years of use, it may not flex back up far enough to allow the switch to fully release (the clicking you hear is the switch snapping from closed or to open). That means the slightest pressure on the button results in no close of the switch because it wasn't allowed to snap to the open position (i.e., it's still partially in its closed position). You can try to flex the "button" areas of the top shell back up or even use a hair dryer to release its fatigued position memory to remember a new higher position when the heat is removed but that can be tricky. Also, the switches are mechanical and will eventually break. If the snap mechanism is weak, the switch could "bounce" several times when closed (you press the button) and the same when opened (you release the button). These bounces can several dozen within a few milliseconds so you don't know there was a bounce but the hardware is fast enough to see several of those bounces which means the OS see more than one close or more than one open. You could open the shell and press on the small tang sticking out the top of the micro switch to feel if it snaps when closed and snaps when opened. The only cure for a broken or limp switch is to unsolder it and solder in a new one. By that point, it's cheaper and easier to just buy a new mouse unless you have some $100+ gaming mouse you really want to keep using. If you are using a mousepad, try a different style. Some mice just don't like some pads. If the pad is a light color then use a dark colored one. If you are using one of those high-tech micro precision pads, some mice don't like those as they see less ridges in the material within their resolution that can confuse the mouse. The mouse has to average the changes it detects, the ridges or changes are at fixed spacing, and the mouse will see 1 and use that while it might not quite catch a change and average it with the next one. You could try changing the sensitivity of the mouse to compensate. If the mouse software lets you change acceleration based on rate of change, so enable that and retest. If you are moving the mouse on glass or shiny surfaces (e.g., lacquered, enameled, or urethaned) then the depth of the material will cause confusion regarding detection of change along with the problem of reflection generating more changes than just how far the mouse traveled. If the mouse worked okay before and you did not change the mouse pad or the surface on which the mouse is moving then this isn't the problem. You never identified you model of mouse. I find the laser mice to be far too sensitive as they can detect the surface from farther away. Hover the mouse over the pad, and move the mouse in circles while gradually moving the mouse farther from the pad. You'll find regular optical mice stop reacting after little movement away from the pad while laser mice will continue to react much farther away. This means when using a laser mouse that the pointer can change as you draw the laser mouse away from the pad and when you then move the laser mouse toward the pad. The pointer shifts as you lift and move the mouse, something that you will often do with a mouse. No pad or desk of any size will eliminate having to lift the mouse, especially if you enable Snap To to automatically move the mouse to the focused object that appears on the screen (e.g., a dialog shows up with OK the default button so Snap To moves the mouse pointer to that button). I don't get laser mice because of them moving the pointer even just a couple pixels which can screw up drawing with the mouse. There may be a proximity setting that makes lifting and dropping the laser mouse less "sharp" on seeing the surface moving away or toward the mouse. You could borrow a friend's mouse to see if the stutter goes away. Or buy a new one for $12 w/shipping. If it is a USB mouse, put it on a different controller than you have other USB device(s). USB ports come in pairs because the controller has 2 ports. So move the USB mouse to a USB port whose paired USB port is unused. That eliminate heavy traffic for another USB device from interferring with the polling of the USB mouse. |

Have you yet tried replacing the batteries in the wireless mouse? Is there an unfettered line of sight between wireless mouse and USB receiver? Did you put anything metallic between them? If you replaced the batteries, and if there is a reset button on the bottom of the mouse, did you press it to reestablish synchronization between receiver and mouse? |

Maybe there's a program peaking the CPU? Press Ctrl+Shift+Esc to see if any programs are eating CPU power. You can check the responsiveness of a system with the DPC latency checker. It gives you some idea how long a hardware event would have to wait to get service. http://www.thesycon.de/eng/latency_check.shtml It's simplistic to say a "busy computer causes stuttering". The OS has mechanisms to bump up the DPC processing rate, at the expense of your looping program getting all the CPU cycles. The OS is actually defensively designed for this stuff. http://en.wikipedia.org/wiki/Deferred_Procedure_Call The only thing it can't do anything about, is system management interrupts (SMI), which completely preempt the running OS, and put the BIOS in control for short periods. Your computer could be running SMI calls 30 times a second. If the motherboard company wrote some bad BIOS code, this is enough to prevent the usage of a motherboard for serious audio workstation usage. And the DPC Latency checker above, is all part of figuring that out (whether SMIs are present, whether the system is responsive). The presence of bad BIOS behavior, causes large spikes all the time in DPCLAT. ******* In this picture, I give a few examples of how Windows remains responsive. These are collected under WinXP. http://i57.tinypic.com/nl3d5j.gif 1) Just started a 3D game. This activity represents the time the Windows OS is least responsive. Apparently flipping the video card to 3D mode for the first time, is really really disruptive. It takes one frame time at 60Hz refresh (16 milliseconds), to service an interrupt and its associated queued DPC. 2) Once in-game and firing rockets, hardware service time is 1 millisecond. If sitting in the desktop again, it's around 0.1 millisecond (green bars). 3a,3b) In this case, I've just started 7ZIP doing an ultra compression, then moved back to my game. The service time for the DPC is still 1 millisecond. If I flip back to the desktop, service time is still in the 0.1 to 0.2 millisecond region. So nothing stutters there, even though I'm gaming and compressing a file at the same time. There are ways to make hardware stutter. One way, is for the kernel to have blocking calls in a hardware path. Which happened on older OSes (Win98 network stack, a complete disaster). A second way, is for hardware to mis-behave, and the OS does one hardware reset after another on the thing, in rapid order. That would be bound to cause disruption. And if Windows is presented with an interrupt storm, by faulty hardware (maybe 15,000 interrupts per second), it has a mitigation technique that continues to make Windows responsive. It's unclear whether this feature has been scaled properly, on later OSes and hardware. So even if you leave a hardware interrupt asserted permanently, Windows can live with that. It just masks them for short periods of time or something. Paul |
