Windows 10: What is this file doing on my Win11 ASUS Creator Laptop: intcusbext.huawei.pnf?

My internal microphone on my relatively new Win11 ASUS Creator Laptop has vanished. I was hunting around for a missing driver or something to explain the disappearance and found these files including one -intcusbext.huawei.cat - in the security catalog. There are several related files as well. What are they doing there and can I safely delete them?

:)

 

inf files and PNF files differ; normal?

Using command prompt or desktop.ini from cmd.exe I have found files in the windows\inf folder that have a conflict. Not all, but a lot of files have the same name with a different extension (inf or PNF). The inf files are dated prior to the laptop build but the PNF files have the current date. Is this normal or is my machine wacked?

 

Huawei


Firstly, if you are experiencing problems with your Huawei E3276 USB Modem hanging ( Connecting ) after upgrading Windows 10 to 1703 Creators edition, try this as it fixed my problem after all other suggestions failed.

First of all make sure your USB Modem is plugged into your usual USB port and do the following.

Click on Windows Start icon in lower left corner of your screen, then select Settings - Click on Network Internet - on left hand side click on Cellular, then UNTICK " Let Windows manage this connection ", then click on " Advanced Options " and go to APN settings and change Default Internet APN from " Automatic " to whatever your known ISP setting is by clicking on the box with the drop down menu and selecting it from the list, mine was Optus Yes Internet, then after selecting your APN setting, scroll down the page and just check that your Modem is listed under Properties - Manufacturer = Huawei.

Close the Settings Window and test your Modem again, if it now works your problem should be solved, if it doesn't, try rebooting your computer and try connecting again and if all has returned to normal create a System Restore Point and call it Modem Fix after Creators Update......I hope this fix solves your problem.

 

Pnf file missing

I’m stuck on the endless loop of automatic repair. I tried doing system restore many times but it states I’m missing a pnf file with the error code 0x80070002.I’ve tried going into safe mode to maybe download something that’d help me but it won’t let me
connect to internet even in safe mode and networking.
