Xbox Controller Dropped Packets

[shane557]

I used the pre-made .img file from this site with a Raspberry Pi B rev 2.0, installed xboxdrv and setup all of the proper configuration files for the controller in /etc/rc.local and used retroarch-joyconfig to add the p1.cfg file to retroarch.cfg. The Xbox Wireless receiver is plugged into a 2.6 amp USB hub and the pi is powered by the hub as well. (Plugging the pi directly to the wall did not fix anything).

When I try to use the Xbox Wireless controller with emulators, it seems as though packets are being dropped (or something else?). For example, even when I am just in the ROM selection menu and press down on the d-pad, it often gets “stuck” and constantly repeats the d-pad down command until I hit something else on the controller. This trend continues within games, too.

Exiting everything and running “sudo xboxdrv” shows me that this is not a hardware problem because outside of the emulation station, all packets are received and the button never gets “stuck.” (E.g. when I press down on the d-pad dd=1 and immediately when I let up, and new line appears letting me known dd=0)

Any ideas?

Although it doesn’t seem like there is much interest in this problem, I have found a solution in case somebody else stumbles across this problem.

In the rc.local file, I had added four Xbox controllers as such:

xboxdrv --trigger-as-button --wid 0 --led 2 --deadzone 4000 --silent &
sleep 1
xboxdrv --trigger-as-button --wid 1 --led 3 --deadzone 4000 --silent &
sleep 1
xboxdrv --trigger-as-button --wid 2 --led 4 --deadzone 4000 --silent &
sleep 1
xboxdrv --trigger-as-button --wid 3 --led 5 --deadzone 4000 --silent &

This turned out to be the problem, as I was only using one controller. To fix the problem, I edited the file down to the first two lines:

xboxdrv --trigger-as-button --wid 0 --led 2 --deadzone 4000 --silent &
sleep 1

After that, everything worked flawlessly.
