Linda / P3D Lose Joystick on "Save"

8 posts in this topic

Everytime that I create a new mapping / assignment and press "Save", at that exact moment both Linda and P3D lose connection to my joystick and I need to hot plug it. Any ideas of what could be causing this? On the latest version of Linda / P3D / FSUIPC... and a brand new install of all of the above on a fresh Windows 10 setup. Any hints?

Blame Microsoft. I suggest you check your Win10 USB power settings. The latest update has introduced power saving modes than can lead to HID devices (joysticks) becoming disconnected.

Search for Power Options in Control Panel. Make sure you have a high performance option selected, then edit plan settings and click on Change Advanced Power Settings. Under USB Settings set USB Selective Suspend setting to Disabled.

Other options exist by editing the registry but you will need to search for this and such changes are at your risk.

Saw that posted but figured that would rather be a random disconnect. This happens literally every time I hit save. Will give the fix a shot though and report back

Tried the USB power fix and it didn't solve my problem. What is strange is that it only seems to happen to my CH Throttle. My Saitek Yoke doesn't get disconnected at the same time... and it definitely happens immediately when hitting Save in LINDA... So I still suspect this is a software bug. Any other suggestions or ways that I can debug?

Please follow the procedure in the pinned bug reporting thread and send me a copy of the fsuipc4.log and linda2.log. This will allow be to better see what may be going wrong.

Hi Scot,

Ok, I went through the repro steps, although this time, I found that before I could even do anything in LINDA, the throttle would be disconnected. Essentially I start the sim, and while LINDA is starting up the throttle works. As soon as LINDA finishes loading the joystick no longer works. I'm testing by using axis feedback (the rudder)... so I can see the pedals responding to the axis input while Linda is loading, as soon as it loads the devices stops working and inputs are not recieved by LINDA nor P3D.

V2.9.3 (496)
FSX Default
P3D V3.4.2.2.19868
F-22 Raptor (Defualt P3d)
FSUIPC 4.966c

The logs are here:

Thank you for the logs. I will examine them once I can get to my computer. 

If you have device axes disconnecting from Windows, this has nothing to do with LINDA. Have you used LINDA before without this problem? I suggest you try your set up using only FSUIPC4 for both axes and buttons and without LINDA.

Sure, that makes sense, what is strange is that the startup in LINDA invokes this disconnection and also continues to cause it when triggering the Save command. I'm only a novice C++ developer, but there seems to be some correlation there.

I've used LINDA before without problems, but on FSX, on Windows 7 and on an older version of LINDA. 

I just did an 2 hour flight... and found no disconnects or issues when only directly mapping to P3D. Didn't try FSUIPC button mappings though, but will next time.
