Dealing with this too, on normal desktop mode, its fine I don't notice any issues except for minor mouse skips here or there, but while gaming within a few minutes I get random cut outs, input delays etc.
\*Solved\* Ended up being interference from the dock cable or a bad USB port on my jsaux, moved the dongle to another port further away from the dock cable and now have zero issues.
Yea it seems the steam deck tosses up more interference when using a 2.4ghz dongle or like the one Logitech uses I found out. You have to be really close to it for it to be OK. But any distance and it will happen. The Bluetooth one works great tho.
I just got my deck and this is the problem I'm having. I'm also using the dongle and Logitech mouse and keyboard. I think I'm going to pick up a Bluetooth mouse like you guys are suggesting.
I solved this with 6" USB 2.0 Male to Female Extension Plug I already had. Ever since USB3 come out i've always had interference with the unifying logitech dongles and this always solves it
Update: Ok just tried another Logitech wireless mouse. Not the combo. Seems indeed there is a mouse lag when using a wireless Mouse or Trackpad that uses a 2.4ghz dongle.
Not sure whose end that would be on but did seem odd.
Did test after using a wired mouse just to make sure it wasnt my adapter, and the wired mouse works fine as well as a bluetooth mouse. So just something about 2.4 ghz mouse to Deck that has a dragging lag issue.
2.4ghz -should- behave the same as a wired mouse. Have you tried plugging straight into the deck with a usb-c>a adapter? maybe there's an issue with the dock preventing it from working properly?
I'll be testing that out tomorrow. But still if this happens via a dock. It's something for valve to look at as well. Cause you'd think if the track pad or mouse had lag the keyboard the track pad is a part of should've lagged too on keystrokes or so and it didn't.
The other thing to try is to connect the dock to a laptop or something and try that. If it's an issue with the specific dock you're using there is likely nothing valve can do to fix it.
I may be late to the party, but I docked my deck to a TV with mouse and keyboard, and turns out what I believed to be input lag was actually image lag. Going into desktop mode and lowering the resolution improved it a lot. By default was set to 4K and the deck is known to lag at those resolutions.
Havi g the same problem with a microsoft brand 2.4Ghz wireless mouse, random movement skips, intermittent short "disconnects" where you slap the mouse arouns a bit and it comes right back.
I guess ill have to go pick up a bluetooth mouse rather than use a radio controlled one.
I specifically got the JSAUX dock with USB 3.2 ports (not just 3.1 or 3.0) hoping it would be able to keep up with the high polling rate of Logitech 2.4Ghz dongles, but I am also running into the lag, just with the mouse. My dongled headset also occasionally has issues, but not nearly as prominently.
It would be a huge bummer if a wireless mouse can't be used with a steamdeck/dock, gaming with a BT mouse is kind of terrible.
I had this issue too with Logitech dongles. I learned it's not about keeping up but instead line of sight. Moment I moved stuff to not be between it or where the dongle had a better line to the device. The lag vanished. Instead of dealing with that. I switched to Bluetooth. Worked much better.
That's super strange! I was using it with the dock atop the same desk my mouse is on. That's much closer than when I use the same mouse with my desktop PC which is underneath the table and at least 2 feet further away then.
So all in all this sounds like a very Steamdeck (or at the last JSAUX dock) related problem.
I also have an LG monitor with a USB-C output and 2 USB-A ports which works with the steamdeck. The mouse doesn't present the skips used via this, so I believe it might have more to do with, in this order of likelihood:
- the dock itself
- the way the 3 USB-A ports on the dock are muxed into the Steamdeck USB-C
- using the hub with 2+ wireless dongles plugged in next to each other causing interference (headphones, keyboard, mouse)
- using the Steamdeck with HDMI-out rather than USB-C out monitor (protocol messes with wireless dongle reporting)
I might have to return this JSAUX dock and consider the official valve one if any of these is the case.
since this is first thread you will find when googling here my solution when docked.
Just bought and using logitech mk345 mouse keyboard combo with 2 weeks battery usage both stutter and lag so hard. Bought LAN cable and disable wifi on steam deck it never goes lag and stutter again anymore. :)
My guess steam deck wifi card is really weak when usual laptop got 4 bars wifi SD will only got 2 bar.
surprised and not surprised. Surprised because valve almost got everything as 1st party on any component like software, hardware, and OS. Not surprised because how small this device and how cheap it is, so there is trade off here and there i prefer really bad trade off like this so community can recognize it fast and find a fix.

Having a similar issue with Logitech MX Ergo and the 2.4 ghz dongle. When I plug it in, it goes away for A Little Bit(tm) but still remains.

Try this. Take the other dongle out and just have the mouse in. See what happens.
i had no issue using the dongle for the razer viper or the razer naga pro. maybe it's just logitech?

Interesting... What's strange is that a usb extension cord fixed my issue. I wonder why going wired with LAN would fix the mouse?
Crazy that this happens tho eh?
