Bluetooth Mouse lag - Sometimes
If I use my Windows PC all day long I’ll experience a mouse lag for a few
seconds every once in a while. It’s as if the processor is slowed down or something. Movement on the physical mouse isn’t updating on the pointer on screen. If I switch to the trackpad that works. If I use a non-bluetooth mouse it never happens. It only happens when I use the bluetooth mouse and it takes a while. After a couple hours of use it just happens and then returns to normal. It feels like radio interference. I’m moving the mouse around and all is fluid and normal, then becomes choppy and non-responsive, after 5 or 6 seconds it returns to normal. Any words of wisdom on this? -- Peter Kozlov |

I suggested a more recent driver but I did so because I had similar issues until I used a program to find me the latest driver for my hardware. This only happened on my old i3 laptop though. |

In my case it is caused by activity on a USB3-connected disk. If the disk is attached but idle there is no interference. But Windows cannot leave well enough alone apparently, and when I see the light on the disk flickering I can expect the mouse operation to get "choppy" for a few seconds. Alas, Bluetooth, USB, wi-fi (low-band) routers (especially those with USB ports for NAS hosts), cordless phones, microwave ovens, baby monitors, and several other devices all share the /unlicensed/ 2.4 GHz frequency (if licensing were required then every user would have to get one before they could use these devices). Since you narrowed down the Bluetooth interference to when the USB3 drive is active, have you tried using a better USB cable, especially a shielded USB cable? In the OP's case, it is likely the USB cable is attached to the mouse, so no way to change to a better cable for the mouse and are stuck with a manufacturer who shaved a few cents by using unshielded USB cable (which is typical). However, in your case, you could change to a shielded USB cable to the external USB-attached drive. A metal-cased USB drive would also shield the device but not a plastic-cased one (unless they used foil on the inside). Yep, sometimes a tin-foil hat is appropriate (although better at much higher frequencies is copper alloy 770 aka nickel silver aka German silver, as is aluminum as long as one piece is used due to oxidation). USB3.x spreads the RFI from near zero to about 4.2 GHz depending on the data rate at the time. This will usually not impact a strong wi-fi transmission but can and often will interfere with Bluetooth along with weak wi-fi. Few users have their wi-fi router right next to the wi-fi NIC in their computer so there is signal attenuation (some routers will warn that enabling their USB port can impact wi-fi performance), and Bluetooth is already a weak signalling technology. https://www.intel.com/content/www/us...nce-paper.html (there is a downoad link to the PDF whitepaper) Does your computer use plastic or metal side panels? Unless foiled on the inside with metal contact when in place, plastic won't shield against RF. However, since both transceiver modules are within the case, it could also be a problem of poor design in either regarding their own shielding. Here's an example where the internal USB controller needed more shielding than the manufacturer provided to eliminate Bluetooth-USB interference: https://blog.macsales.com/15990-shie...with-bluetooth The OP and you never stated if they are using a mobile computer (laptop, netbook, tablet) or a stationary desktop. With a desktop, just use wired mice and keyboards as they aren't moving around. Yeah, the mouse moves around but within the confines of a few inches, so just make sure its cable is unfettered from mouse to the back of the desk to eliminate any tension from bending (some mice have very thin cables to improve flexibility at the loss of longevity). The more the mouse cable flexes, the sooner it will break its stranded wires. If you just must have a wireless mouse, use an RF (27 MHz) one - but make sure no one else within 50 feet is also using one (RF cross-talk). Although range is supposed to be only about 6 feet, we had a workstation where the mouse cursor would dance across the screen because someone up one floor and a couple cublicles over also has an RF mouse. If you get a 2.4 GHz wireless mouse, well, you're back into the contention frequency with all the other wireless and USB devices. There are still some IR (infrared) mice available for sale but you must have a direct line-of-sight between mouse and transceiver dongle. Also remember that a wireless mouse is heavier (due to the batteries) than a wired one - as long as the manufacturer doesn't lie about the heft of the mouse by gluing a thick heavy washer inside - and could die out just at that point in a video game without a save function where you'll die if the mouse doesn't respond or is slow or jerk at that moment forcing to restart the entire level/map. |

Also remember that a wireless mouse is heavier (due to the batteries) than a wired one not necessarily, and if it is, not by any significant amount. in other words, the weight of a mouse does not matter. |

Oh yes, this is our nospam god. Despite all the evidence to the contrary, what nospam declares must be how it is. Since you narrowed down the Bluetooth interference to when the USB3 drive is active, have you tried using a better USB cable, especially a shielded USB cable? usb cables are shielded. For USB 1 and 2, shielding is not mandated by the specification. They relied on differential signalling with twisted pairs under the assumption that RFI was equally induced into both wires, along with relying on low-voltage and current. USB 3 has some shielding mentioned in its specification. Super-thin USB cables are that way because of the lack of both shielding of each twisted pair and a braid shield around the bundle. http://www.hardwarebook.info/Univers...USB)#Shielding Notice there are gauge specs (both the same) for shield and *unshielded* USB cables. Oh, but according to nospam, thou shalt always shield despite not mandated to be compliant. http://www.questtechnologyintl.com/p...4#.V_tfI8nLweA Yep, that's an /unshielded/ USB cable and they say so. Most USB makers don't tell you, or they only tell you if they are shielded. You might *assume* if they state full- or high- or super-speed support. In USB specifications, shielding is spec'ed for full- and high-speed but NOT for low-speed (USB 1.0 @ 1.5 Mbps). Since USB has been in use for awhile, could be someone had an old USB 1.0 cable laying around that is NOT shielded. The USB 2.0 specification says: The USB can operate at three speeds. High-speed (480 Mb/s) and full-speed (12 Mb/s) require the use of a shielded cable with two power conductors and twisted pair signal conductors. Low-speed (1.5 Mb/s) recommends, but does not require the use of a cable with twisted pair signal conductors. Shielding is not mandated, nor even twisted pairs, for low-speed. The USB 2.0 spec mentions the connector *housing* is supposed to be shielded; however, I've seen open frames where there is metal to hold the connector but a missing backplate (aka backshield). Also, that the port is shielded (wholly or partially) does not mandate the cable must be shielded. https://www.screenfix.ie/wp-content/...016/10/C40.jpg http://tinyurl.com/yd9s94fl Also see the Intel article on shielded port connectors; see figure 4-6. Oh, you'd have to read instead of proffer your should-be's maxims as absolute truths. Also remember that a wireless mouse is heavier (due to the batteries) than a wired one not necessarily, Please explain how the weight of batteries does not increase the weight of the mouse? Oh, magical batteries of zero weight. Got a URL where I can buy those? and if it is, not by any significant amount. in other words, the weight of a mouse does not matter. So, according to nospam, you shouldn't care if your mouse weighs a couple tons. Yeah, no one ever has to lift a mouse. Instead they have a huge and open desk with huge mouse pads upon where to move the mouse without physical constraints or they up the acceleration so the mouse can be moved a little (provided the user moves faster to move farther instead of moving linearly) making fine control impossible for more than a few pixels. Pinkies WILL get fatigue faster with heavier mice due to having to lift them. Everyone that I've seen claiming not having to lift their mouse when physically observed has lifted their mouse repeated times. nospam is lucky. He doesn't have to repeatedly lift his mouse while working on the computer for 10 hours a day, or longer (like going home to play on the computer there). |

Oh yes, this is our nospam god. ad hominem. Despite all the evidence to the contrary, what nospam declares must be how it is. there is very little evidence to the contrary. the reality is that plenty of people use bluetooth, wifi and usb without issue. Since you narrowed down the Bluetooth interference to when the USB3 drive is active, have you tried using a better USB cable, especially a shielded USB cable? usb cables are shielded. For USB 1 and 2, shielding is not mandated by the specification. good luck finding a usb 1 cable, which has been obsolete for more than a decade (and actually did require shielding for full speed). for usb 2 & 3 cables, the ones that are sold in stores today, are shielded. The USB 2.0 specification says: The USB can operate at three speeds. High-speed (480 Mb/s) and full-speed (12 Mb/s) require the use of a shielded cable with two power conductors and twisted pair signal conductors. Low-speed (1.5 Mb/s) recommends, but does not require the use of a cable with twisted pair signal conductors. Shielding is not mandated, nor even twisted pairs, for low-speed. in other words, usb 2 cables, which support high speed, *must* be shielded. Also remember that a wireless mouse is heavier (due to the batteries) than a wired one not necessarily, Please explain how the weight of batteries does not increase the weight of the mouse? Oh, magical batteries of zero weight. Got a URL where I can buy those? you're assuming a bluetooth mouse and wired mouse are in every way identical except for batteries. that is of course, a completely bogus assumption. the reality is that some bluetooth mice weigh less than wired mice. a typical wired mouse is ~100 grams. here's a wireless mouse that weighs just 32 grams, which weighs less than most wired mice. http://usb.brando.com/tiny-2-4ghz-wireless-mouse_p00511c037d15.html this one doesn't list its weight, but it can't be very much: https://www.newegg.com/Product/Product.aspx?Item=0TP-000J-00AV9 have you ever used a bluetooth mouse? or are you as usual, talking out your ass? any difference in weight is negligible, maybe 10-20 grams for similar size mice. it's nothing anyone would even notice, except on a scale. and if it is, not by any significant amount. in other words, the weight of a mouse does not matter. So, according to nospam, you shouldn't care if your mouse weighs a couple tons. straw man. |
