Brief description of the issue:
There is an access violation related to USB controllers. When installing or updating FS2020, I get a CTD when any USB game controllers are plugged in. If I remove them all, it will install/update.

If I have all 11 of my USB game controllers in (for my sim pit), opening the controls menu causes a CTD with the following crash debugger error:

0xC0000005
The thread tried to read from or write to a virtual address for which it does not have the appropriate access.

When I have 10 or less USB game controllers plugged in, I no longer get the CTD.

The devices are limited in the code and this needs to be increased in order to solve this basic issue.

Additionally, I have been reaching out to support and the discord but have had zero help.

Provide Screenshot(s)/video(s) of the issue encountered:
N/A, its a CTD

Detail steps to reproduce the issue encountered:
Install/update with any USB game controllers plugged in
Run/go to controls menu with >10 USB game controllers plugged in

Thanks for linking this, exactly the same problem! Support has left me hanging for about 2 weeks in my ticket, sadly.

I have had this 0xC0000005 CTD for months. Each time, just before the CTD, the audio wavers for a second. The only error in the eventlog is this errorcode, and a warning about a disk that has been removed suddenly, which is probably the result of the CTD rather than the cause.
I filed 2 tickets for it, and received the same standard troubleshooting guide.
After months living with these CTD’s I finally discovered the cause: USB devices.

I had almost giving up on finding the cause. I have filed two tickets about this issue and got the standard troubleshooting guide each time. Those didn’t help. I also tried almost every “fix” in these and other forums and none of them really helped. One of these tips was completely reinstalling MSFS and I did that several weeks ago. At first it looked like it worked, and I posted so in these forums.
I was wrong though, because after a few flights those CTD;s returned.

I left MSFS alone, afraid even to start it up again, until a thread about this issue on Avsim caught my eye. This stimulated me to try again.
I have a specific test route from ESUE to EGPN (low alt IFR) that is guaranteed to give me a CTD, usually before I am halfway the North Sea. It does not matter whether I use AI traffic, community mods, simconnect clients etc. or not. It crashes without these or with these.

This time however I decided to do the entire flight without ANY USB controllers. I only had 1 USB hub, a mouse and a keyboard connected. To take off I made use of the AI pilot, and switched to autopilot enroute.
This time, the flight completed without CTD!

After some testing I have found that it doesn’t make a difference whether I have community addons, or simconnect cliens running, or traffic or Azure ATC. Each test is the same: without USB devices the flight is completed, with (some of) them plugged in, it Crashes To Desktop.

After getting my hopes up with several fixes that appeared to work, but proved not to after a few more flights I tested this more thoroughly. I have flown this in several configurations, but the only change that makes a difference between CTD or not is whether I have UBS devices connected or not.

It could be my X570 chipset, of which AMD has recently acknowled to have USB issues, or it could be MSFS, which also had issues with USB devices. They might be related.

I have a likely cause for my case of 0xC0000005 crashes. I don’t have solution yet though. Perhaps Asobo or Microsoft needs to come with another patch, or AMD. I could sell my motherboard and CPU and go back to Intel. With over 300€ spend in the marketplace already I am too invested in MSFS and besides, when it works, it is a fantastic flight simulator, the best I ever ‘played’, and I have been doing so from the FS 5.0 days.

Do others still have this issue? When i plug in a USB stick or other USB device (also non MSFS related devices) the sim crashes. I was doing a multiple hour flight and i plugged in a USB stick.

I don’t understand why this isn’t a high priority bug.

Mentioned something similar in another post. (CTD Bluetooth Controller)

I have discovered this USB game controller issue with my set-up

I fly exclusively in VR and, like many others, I had no CTDs until SU5 and the latest hot fix. I now usually have a CTD, especially with bush trips, when taking off or soon after becoming airborne.

I have tried most of the tests and ‘fixes’ suggested but none helped.

Out of desperation I replaced my (new) VKB Gladiator NXT joystick with an old but well proven Attack III and to my surprise I was able to complete a stage of the Norwegian bush trip without any CTD.

It may be just luck that I had no CTD, which only time will tell, but I mention it here as it may help others pin down the source of their CTDs. If you can, try changing your flight control(s) to see if that helps.

Funny, i have exactly the same trim wheel. Indeed the pause seems to be shorter now. Also for my Xbox controller.

As awkward as it sounds, knowing what l have just learnt, l would try connecting my USB controllers when the sim is loaded at the sim’ menu if l had CTD’s in the early stages of the simulator loading.

EDIT: In retrospect I would try with no USB game controllers connected.

Having now done a little bit of searching, l see that some people are having CTD’s related to USB controllers.

I take comfort from the fact that you have a single pause when using the trim wheel for the first time.

There is something ‘cranky’ going on in the background with this simulator.

Thanx, Capt’ :grinning:

BRGDS.

I’ve been having various CTDs mostly in-flight and in some cases the game once relaunched would not detect my USB gamepad anymore (PS4 controller) until I rebooted my computer. I suspect the controller’s driver crashes alongside the game (which only happens with MSFS) although I’m not savvy enough to check, not that I want to check anyway.

Edit : I’m starting to suspect that in my case, the USB connector of my controller is a bit flimsy and may disconnect/reconnect from time to time, which in turn causes msfs to crash. I’m gonna switch to my old Logitech gamepad see if it’s any better.

Edit 2 : Well it’s stable so far, it seems most of my CTDs were due to crashing on USB controller disconnection.

Hello,
A CTD fix regarding peripherals was applied last year in 1.19.8.0. Could you please confirm if this is fixed for you?

I will mark this resolved if I do not hear back in two weeks.

No response from OP.
