Crashes caused by SiUSBXp.sys.

[Jaky333]

Hello, I had my computer diagnosis recently, however unable to find the problem that is related to the error. Was wondering if the community knew anything about this driver issue and how to address it. My computer would be crashing at random times, which would give different BSOD screens.

I have tried reformatted my computer and tried updating drivers.
Ran driver verifier, which people said it was related to 'Silicone Labs USBXpress Development Kit', and unsure what to try next. I haven't been able to find anything online that can help me address this issue.

The only program that was identified with it, was the CAM from NZXT Kraken x61, which I have uninstalled, but still experiencing crashes.

I had a look on the silicon Labs website, however was unable to find any drivers that I could download that might help fix my issue.

I could suggest you try on here as well: https://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/

but they also may not know what that silicon labs file is part of. I would think there must be a way to figure out what installed it.

The CP2102N devices, part of the USBXpress family, are designed to quickly add USB to your applications by eliminating firmware complexity and reducing development time. These highly-integrated USB-to-UART bridge controllers provide a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space.

CP2102N includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, and Universal Asynchronous Receiver/Transmitter (UART) in packages as small as 3 mm x 3 mm. No other external USB components are required for development. All customization and configuration options can be selected using a simple GUI-based configurator. By eliminating the need for complex firmware and driver development, the CP2102N devices enable quick USB connectivity with minimal development effort.

as we found, these could be part of anything


bizarrely, this says the file is actually part of windows - http://www.fixoserror.com/fix-siusbxp-sys-blue-screen-error-step-by-step.html
and has a few suggestions
1. open command prompt (admin)
type chkdsk /f and press enter
this will make 2 paragraphs pop up, click Y to let PC run at start up
restart PC to let scan run

2. open command prompt (admin)
type SFC /scannow and press enter
system file checker fixes system files. Seems unlikely to be fix after a fresh install but worth a try

3. run an AV scan
Not sure rest of tips will help.

Hey, thanks for the reply again Colif

I have yet to post on bleepingcomputer, will do that soon.

But I have tried the 1st and 2nd tip and haven't found anything. I've been using window defender, do you recommend any free one I should just try?
I've personally had poor experience with norton and AVG

 

[Colif]

try Bitdefender Free, I use the paid version and never had any problems with it

i wonder if they can tell us what is using it, its the mystery part really. its being used on some of your hardware but what exactly

 

[Jaky333]

Sorry for the late reply, still scanning my pc, but everything is looking fine from the scan at the moment.
However, my computer has been crashing a lot more recently. Still going through exams so haven't been able to give my computer the full attention, but quite frustrating where it is crashing every so often.

I haven't been able to post on beepingcomputer.com for some reason, not letting me create a thread.

 

[Colif]

did you make an account over there (I assume this was obvious). I don't use that forum so not sure why it would react like that. I cannot see anything about it on google?

take your time if you are busy

 

[Jaky333]

Hey, sorry for the wait. Just an update that I was able to post on bleepingcomputer and the feedback is extremely informative.

Thank you for everything so far, will be working through those recommendations.

 

[Colif]

That looks promising. Odd the driver dates from 2010 but sure they will help you figure out what its tied to.

 

[Jaky333]

Sorry for the lack of update. Was testing it to make sure everything is good.
After 2 months of crashes, I can finally say I have been able to fix the issue.
Turns out it was a hardware issue and not sure if siusbxp-sys is the main problem, but it was a bad ram stick which I was able to take out.

Thank you Colif for sticking with me the past 2 months and helping me with each new problems and recommending solutions to me. Cannot thank you enough and if it was not for your dedication, I would have gave up already and looked at buying a new computer. Feels good to be able to finally use my computer and not worrying about it crashing, even better that it is fixed right at the start of my holiday . Thank you again Colif, look forward to our next encounter.

Didn't we check ram at any stage?

I guess it kept blaming same thing, if it had been more random it would have been more obvious.
