Mouse Lag When Transferring Data

[Appletax]

Anytime I write/read data via USB (e.g., with flash drive), my mouse lags bad. Marathon mouse does it, MX Master 2 and 3 does it. Changing ports does not help.

And, my wireless keyboard will make typing mistakes.

What's up with this?

Plugged my MX Master 3 into the computer with USB-C cable, but it only charges it.

Got the business version of the MX Master 3 and MX Keys keyboard coming with the Bolt bluetooth receiver. Hoping it doesn't have this issue.

Sounds like the USB bus is saturated. Check drivers check MB drivers/SMBus, etc.. The USB-C port should work, not only charge. Check BIOS updates.

Are the ports in question "header ports" in the case, connected by a cable?

I know you said changing ports doesn't matter but have you tried the back USB ports that are directly on the MB? Have seen plenty of "case hubs" not be worth a poop. Make sure to try the flash drive on a different "hub" than the mouse/kb.

USB 3.0 is known to cause interference with 2.4ghz stuff like wifi, bluetooth, and wireless kb/mice receivers.

I try to keep my receivers as far away from USB 3.0 ports as possible, and when using on a desktop I almost always use an extension cable anyways to move the receiver closer.

Just try a different USB port. USB is actually kind of strange. PS/2 uses an interrupt forcing a key read when you press a key.

In USB, the press is buffered then the computer READS the buffer. You are NOT actually sending keypresses at all merely posting them to be read, so the computer polls USB.

Case and point a USB keyboard can recognize only about five keys pressed down at the same time. If it is a polling issue, it might work better on a different USB port... might not.

Should have mentioned that the issue occurs with lots of computers that I have worked on.

Tried different ports including USB 2.0.

Bus isn't saturated because I'm just transferring data from a laptop HDD.

No lag or mistyping with wired mouse and keyboard.

Will report back on how things go with the Bolt devices. They aren't 2.4GHz - they're low power Bluetooth.

Which is still 2.4ghz.....

I've always had lots of hell with wireless mice.

Well dang. Lol. If the fancy schmancy new Bolt receivers don't do trick, I suppose nothing will.

I sure wish the expensive MX Master 3 mouse switched to wired communication when plugged in.

Transferring 160GB of data from a laptop HDD over USB using Fab's Autobackup 7 Pro caused lag for like 2 hours with my mouse. Didn't use the PC much, so not a huge deal. In future, will switch to a wired mouse as needed.

I, on the other hand, have never really had problems with wireless mice. But I do generally buy fairly expensive gaming mice, usually a logitech or Razer... and I have a bunch of signal flying around.

I just bought one of these beauties, for my 6x686 "Retro" Setup. COM Port Mouse circa '96

Awesome for RMB Clicking!

I just run wired for my Mouse & Keyboard and have my Keyboard on a USB >PS/2 adapter, mostly just for port saving, I get that this may not be feasible for all and every setup but prefer it to wireless most times.

I, on the other hand, have never really had problems with wireless mice.

And I, too, have had this experience with everything from the cheapest (currently one client is using an ONN wireless mouse that works flawlessly) through expensive mouse/keyboard combo kits. Never a gaming mouse, though.

Wired mouse + one of these: https://www.amazon.com/s?k=mouse+bungee
It feels like wireless
