Random short disconnects from mouse and keyboard

[psyvc]

So I've fixed my disconnecting issue, or so I thought. Now it's not only the mouse, but the mouse and keyboard?

it's so fast that the rgb of the mouse doesn't even turn off only my keyboard's. I don't see any disconnection from the mic, but I know both the mouse and keyboard are affected because the mouse gives a orange light indicating that is has been plugged in.

I don't really know what to do, the disconnects are very random and only seem to be happen when I use them. Anyone know any tips? I literally just got this problem like 2 days ago.

Mouse:
Plugged into front of case into USB 3.0 Port, HyperX Pulsefire Haste
Keyboard:
Plugged into back of mobo into usb 2.0 port, GK61 hk

Hi,
Either bad signal or bad power/ batteries in the devises.
Where is the computer in relation to where the devises are.
Image might be best.

 

[questionable]

Let me guess, it's a Ryzen. USB problems got improved with the AGESA update that was supposed to specifically fix them but some owners continue to experience problems.

If you look through the replies here you can see a decent amount of people having success after replacing the processor.

Spent the weekend troubleshooting and fixing the notoriously hard to replicate AM4 USB disconnectivity issue. It was hard to find info about and I hope this helps others.

I can't get pictures right now but I can explain in text, The devices aren't that old they're both almost a year old now (I've also never damaged neither of them).
The computer is on my desk I do clean everything out from time through time.
I'll show pictures once I get home

well it is a ryzen cpu, I'll check through, thanks for providing info about this I never knew

Update:
I was playing some games and my keyboard and mouse literally just stopped turning on, the mic is ALSO a usb device but it’s working just fine

After restarting the Pc the keyboard and mouse turned on again, but why is it only affecting the kbm

 

[psyvc]

tried swapping the mouse to a 2.0 port, am still getting random disconnects from the keyboard and mouse

questionable is about the motherboard socket type, this case AM4.

What CPU\Motherboard does the system use ?, you can try using CPU-z to get the needed information.

am using a ryzen 5 2400g and a asus prime b450M-A

am now using the two back usb ports on the mobo in hopes of possibly fixing this, I really don't know what the culprit is

Check what bios version you have and check ASUS's site if there is a newer one available that has fixes for your issue.

PRIME - All Models｜Motherboards｜ASUS Global

In ASUS 「PRIME - All Models」 - Motherboards / Components , you could find most appropriate Motherboards / Components based on product features, specification or price. And you also could get product's detail information and comparsion, even add it into the wish list in buy page.

Probably be good to put a ticket into asus and the keyboard and mouse makers, mic maker maybe

I am already on the latest bios

well that aged well am still getting issues

It's now getting my usb Microphone, I will keep trying to swap ports, I am trying out the reddits troubleshoot methods gonna hope this works
Maybe it's the power plan so I've changed it to high performance

So, I've fixed all the USB devices going crazy, but now am back to the 1st post where the mouse is disconnecting randomly. Should I RMA it? I really don't know what to do anymore. I will try the last things possible which is updating the chipset driver and changing the pci slot in power plan

So chipset seems good, my mouse is still the only thing getting random disconnects, I'll try swapping one more time

always post the system stats

you need to raise your SoC voltage


without knowing the full hardware of the PC i cant suggest any settings, but it's always ALWAYS necessary to post the hardware you're having trouble with if you want accurate help

I'll just throw wild guesses:
ryzen 3000 series CPU, XMP on, two dual rank sticks or four single rank sticks of RAM, likely 3200 or above

Ryzen 5 2400g, dual stick 8g 3000mz RAM, psu is the 650BQ bronze I believe. Asus prime b450M-A mobo
XMP is on. TPM was on, currently turned off. Windows 10, Also changed rpm on my fans. That's the only thing I changed in bios, I don't know why TPM got turned off am going to turn it back on in a few.
This is not a prebuilt computer so I know nothing else in bios changed

Hey, on my main pc I use cable extensions to route the rear port to a better place, disconnects are usually loss of signal (probably from interference from other devices).

A usb or wifi antenna within a foot of a receiver can cause havoc, but you can safely put 2 receivers next to each other and they work fine.

My living room pc has 2 usb receivers on the front about 2 inches apart for a wireless kbd and mouse both are dif brands it works fine but both are aimed more or less at the devices about 15 feet away.

I do have a wifi card with antenna's at the rear, but it's now only affecting my mouse. Wouldn't it affect all them too?

Ryzen 5 2400g, dual stick 8g 3000mz RAM

Right, but... what are they?
Timings, voltages, number of ranks per stick

And then the important question: what are they running at?
CPU-Z can be used to get screenshots of the SPD and RAM tabs to show answers to both of those questions, use the windows snipping tool so you're not posting the entire screen

Heres mine for comparison, with DDR4 3600 running at 3866

With ryzen if the memory is clocked too high you get black screen crashes, but if the memory controller is clocked too high (which is directly linked to RAM speed), you get errors on the PCI-E bus and USB ports attached to the CPU resulting in devices dropping and reconnecting

Your CPU is effectively first gen ryzen with an APU on top, and roughly follows these limitations - at best 200Mhz above on each step

To further back that up, the official product page for your CPU is here:
AMD Ryzen™ 5 2400G with Radeon™ RX Vega 11 Graphics | AMD
You'll note that DDR4 3000 isn't officially supported, and is therefore overclocking
2933 is supported on single rank memory modules, dual rank drops per the chart above

TPM and secure boot are enabled by default on any BIOS that supports windows 11
TPM gets disabled by a lot of people as a troubleshooting step since there was a BIOS/windows bug that potentially caused stutter for ~6 months

A google search for 2400G memory overclocking led to this quote from toms hardware

We also adjusted the VDDCR SoC voltage, which is a single rail that feeds the uncore and graphics domains, to 1.25V. That allowed us to dial in an easy 1555 MHz graphics clock rate and push the memory up to DDR4-3200 with 14-14-14-34 timings.

Which gives the suggested voltage of 1.25v on the SoC as a maximum to try - you'd have to confirm what your default voltage is, as it can vary between boards

I'll check the voltage right now, also I may have miss used the word "dual" it says single on the cpuz chart so I don't know if that changes anything you've said

Some versions of CPU-Z state 2x64 instead of dual channel which is extremely annoying, make sure your ram sticks are in slots 2 and 4 (with 1 being closest to CPU socket and 4 being furthest)

Ranks are often (but not always) as simple as whether memory chips are on both sides of the stick of RAM - 'two' sticks of ram in one slot, but that's hard to tell with heatspreaders these days, and some rare RAM modules buck trends and could go either way

Usually higher capacity memory runs dual ranks (8GB are single, 16GB/32GB are dual) - but not always

2x8 single rank is good for stability (dual rank gives a small performance boost, but is harder to run at higher clock speeds)
Timings look good for ryzen, and they're running the XMP values - tRC is oddly a +1, but if it automatically did that i see no need to change it


Check the RAM is in 2 and 4, find out your stock SoC/System on chip voltage (and raise it in smaller steps - so if it's 1.0v raise to 1.05v, to 1.10v, to 1.15v etc) to a max of 1.25v
Give it a day or two between changes, you dont want the extra heat of higher voltages for no reason, but it may change from a dropout every hour to every 8 hours to every 48 hours, and you'll want to to give it time to know where it's really at


Changing command rate/CR from 1T to 2T might help, on older platforms people made a huge deal about 1T for performance on DDR3, but on DDR4 it's nowhere near as important

It indeed is on slots 2 and 4, SoC is auto on 1.1, and it’s auto + voltage I will try to lower mz for the memory

nah just raise the SoC to 1.15v
You could go right to 1.25v SoC and 1.4V on the DRAM and have 100% safety for 24/7 use, I just suggest the in between steps since it might save you 2-3C on CPU temperatures

The APU's need higher SoC since that also powers the onboard graphics
memory controller, PCIe, SATA, and USB (four ports on the rear of mobo are straight from the CPU) are all powered by that one voltage, and it can simply droop down under load and make any of those devices reset briefly

This is the flaw that early ryzen had, in that Intel locked their DDR4 speeds down each generation while AMD did not - you can get a launch day x370 motherboard designed for DDR4 2133, slap in a 5950x and DDR4 4000 and it'll work fine until you enable XMP, where it just needs some minor BIOS tweaking.
You just happened to hit right on the very edge of stability, but theres zero reason you cant use that ram at it's rated speed or even overclock it

I agree with most of this, but do not just blindly raise dram to 1.4V. As seen on OPs CPU-Z screenshot his ram has samsung memory on it. With these timings I'd say there is a high probability that this is samsung C-Die which loses stability if you raise the voltage. They typically have a sweetspot around 1.32-1.33V.

1.4 is perfectly safe and wont cause any issues on B-die, the people running into heat issues are running 1.5v and overclocking the crap out of it

XMP is 1.35v, 1.4v is barely an increase

 

[The King]

Also try this Enabling USB Selective Suspend in the power plan if its not already enabled.

It has been known to help even solve issues with USB disconnect problems provided you have your VSOC and IOD at the correct voltages.

You might have misunderstood what I was trying to say. I am not concerned about safety or heat. Also I'm very confident OPs kit is not B-die, but C-die. And C-die will just get worse stability if you increase the voltage. Even the typical 1.35V XMP that most C-die comes with is more than you would want ideally. Increasing it past that could only cause more problems in terms of stability and errors.

it's literally only affecting the mouse now , all other USB devices are fine I even swapped the ports with my keyboard and it still only targets the mouse. I've tried for a hour straight on another device to try to replicate it and I didn't seem to get any dropout. Should I consider RMA for the mouse? It's getting so annoying when working and it's especially annoying when gaming

What mouse is it? What USB port is it connected to, and what is near the mouse?

If it has multiple wireless connections, what one are you using
