Summary:

The RC Controller that I'm using for a PC game to practice flying quads is, I suspect, passing power through the line and causing my machine to shut down.

What I'd Like To Do:

Change the wire configuration so that my PC stops crashing

Details:

  • RC Controller: FlySky FS-i6
  • Game: Liftoff on Steam
  • Cable Connection: S-Video to 3.5mm Audio Jack to USB converter

I have the USB dongle open. I think if I can just find a way to stop power from being passed into the machine it'll work, but I'm not sure, that's why I'm here.

I've tried using USB ports on both the motherboard and also USB ports on a dedicated USB card. Both produce similar results. Not long after starting the game and using the controller, the entire PC restarts. In the years I've had this machine, I've never experienced this.

    \$\begingroup\$ I think you are going down the wrong path, thinking its power coming from the controller, its more likely a SW issue or HW issue with the PC.....can you give more information on why you think its power from the controller? \$\endgroup\$ – jsolarski Dec 20 '18 at 23:31
  • \$\begingroup\$ The reason I suspect the power from the controller is the issue is because I've had wonky usb results in the past while powering an arduino externally as it was plugged into my machine. It never caused the machine to shut down but there was an effect \$\endgroup\$ – Anthony Russell Dec 20 '18 at 23:32
  • \$\begingroup\$ I would expect that if your controller was externally powered, and directly hooked up to the usb, but its cable to dongle to usb. before doing any mods to your usb dongle, I would suggest using a USB hub in between to see if you get the same results. If you do, then I would start looking at the drivers and SW first. or try another PC. \$\endgroup\$ – jsolarski Dec 20 '18 at 23:42

    \$\begingroup\$ it soulds a lot like a driver problem - ask in superuser. \$\endgroup\$ – Jasen Dec 21 '18 at 1:12

    \$\begingroup\$ USB port should be protected on the computer side against over current, so I would be surprised the reason is that it's drawing too much current. It might be Static ESD causing a reset. How does the computer stops ? blue screen or just power off instantly? \$\endgroup\$ – Damien Dec 21 '18 at 13:32

It might be Static ESD discharge causing a reset on some chip of the motherboard.

Static would build-up on your body, transmitted to the remote through the metal joysticks and to the ground line of the USB going right onto the motherboard, as it seems there is no shielding connected on your usb dongle.

Try to connect a wire from some metal part of your remote to the PC casing (make sure it makes good contact) and check if it still happening.

  • \$\begingroup\$ I took the shielding off the dongle so I could get a photo and see if there was any broken solder points lol. I have a ESD bracelet, I'll try hooking it to my controller and see if that works. \$\endgroup\$ – Anthony Russell Dec 21 '18 at 13:38
