Question: Does it work with Linux?
Document: Works fine. Only I needed connect and works, in Windows 8 and GNU/Linux (Debian Testing). The dinput mode is perfect to old games and xinput for new games.
I chose 5 stars because not only does this item work perfectly. It also works beautifully on my tablet!! Exceptional bonus!! !
If you are looking to put your Pro Controller to good use on your PC, stop wasting time trying to get that Vjoy and Toshiba Bluetooth stack to work and buy this. It works perfectly right out of the box and right along with every game I have on my PC. Enjoy!
This mode is generally better for older games and use with emulators, which may expect Dinput. Once calibrated, I can easily use the sticks with 0% dead zones and get great responsiveness in emulators.I only have one problem with the adapter, and that is that the radio stops blinking and ceases to work after several seconds in Dinput mode.
Absolutely incredible. This device lets you make full use of the Wii U Pro Controller on a PC. Vibration works well, controls work like they should. Oddly enough, I'm used to purchasing electronics on Amazon and having them not work, but this was not the case here. No problems at all. Very easy to use. The directions are right on the back, and I set it up in less than a minute.
When I stuck it into a USB 2.0 port  it would stay on for about 10 seconds after I synced it and then shut off. After fiddling with it for a couple minutes, I plugged it into USB 3.0 and it worked without problem. Might just be my configuration but in case anyone else has this problem.Overall great buy if you want a Pro controller to work on your PC if you don't want to use the technical way or it just doesn't work.
All the buttons work and the mappings work perfectly. As others have noted, A is set to A on the controller, so it's in a slightly different place than on the 360 controller, but since the right stick is also in a different place, it's not a big deal. Playing with the Wii U Pro controller has been a joy - it's worked great with Spelunky, Skyrim, and Dark Souls II so far and I'm eager to try it out with some other games and emulators.
This thing is great; it works as advertised and was very easy to set up.I bought it primarily for playing games in Steam Big Picture and it certainly gets the job done. When operating in xinput mode, controller-compatible games work with zero-configuration. As others have mentioned, buttons are mapped to their respective letter which creates a small problem since X and Y are swapped relative to the xbox controller layout.
Like everyone else has said, it works great on the PC and is easy to set up. However, the PS3 functionality is awful. The face button assignments are all off. X = Cross, A = Triangle, B = Circle, Y = Square, + = right stick, Right stick = start. And its doesn't even work at all with some games (ex: Dark Souls). Worst still is Mayflash has terrible support. No support page, troubleshooting, or forum.
Hey All,Bought this adapter because the Bluetooth work around wasn't working for me. It arrived quick, was super easy to install (Windows 8.1), and works well as either a 360 emulator or regular controller (Really like this feature).Just a note: with 360 emulation, the XYAB buttons are mapped to the XYAB button on Pro Controller (meaning they are in a different place than a 360 controller). Be sure you are OK with buttons not being in the same place.
Answer: I actually haven't tried that out, I can test it out in a bit.Update: I have tested it on Ubuntu 12.04. Nothing extra to do for the controller or adapter to be detected. I gave it a go on the zsnes emulator and configured the inputs and it worked out fine for every button. Played Super Mario World on it and everything responded like it would when I'm using windows. I have yet to try other games/programs on Ubuntu.
