Keyboard and Mouse for PlayStation 4 Games (second prototype)

Why did you do this?

I like playing shooter games on PC but my laptop is too weak to play them. Game consoles do not support USB keyboards and USB mouse, they only support gamepads. Gamepad controls are not suitable for shooter games, using a keyboard and mouse is much more comfortable for gameplay.

How does it work?

I designed a circuit that features a microcontroller and USB hub. The keyboard and mouse plugs into the USB hub, and then the microcontroller takes the data from the keyboard and mouse, translates them to the data format used by the PlayStation 4. It does the translation in a way as though the mouse was the right thumbstick, and the keys are mapped to buttons (the WASD keys are mapped to the left thumbstick).

If you want to buy one from me, you can’t, I don’t want to sell anything. If you want to buy something similar from somebody else, try the XIM4 (my top choice), CronusMAX, Venom X, etc. (if there’s another product you would like to see on this list, give me one to try out first, and I’ll add it if it works)

Development Story

Latest News – July 20 2014

I wanted to share this story because I am very happy that I finally managed to get this far! Anybody who is attempting this and thought it was impossible to do can now breath a sigh of relief because it definitely can be done.

I have already accomplished a similar project that worked with a PS3 (UsbXlater), something that connected to the PS3 via USB that translated keyboard and mouse data format to gamepad data format.

Once the PS4 launched, I reversed engineered the USB protocol used by the DualShock, and then attempted the same technique. But… Continue reading →

UsbXlater, DualShock 4, PlayStation 4, Weekly Report Dec 15, 2013

I haven’t worked on the firmware for the UsbXlater for a while. This is because I really want it to work on the PlayStation 4 by spoofing the DualShock 4, but after some heavy investigation. It seems like this is impossible (in the sense of spoofing).

On the DualShock 4 circuitry, I have recently found the UART (aka serial port) pins for the Bluetooth module’s HCI (host controller interface). I used my logic analyzer to capture the data from the HCI. The results are posted on my wiki page about the DualShock 4, along with the pcap file with the entire capture.

The PlayStation 4 does not seem to accept input through USB. I did get UsbXlater entirely working and replicating the behaviour of a real DualShock 4, but the PlayStation does not respond. The Bluetooth connection is always active during this time.

Over Bluetooth, it seems that the L2CAP packets that are sent containing the report contains 4 bytes at the end that appears to be random. This could mean it’s a checksum or a hash. Update: it’s a CRC32, with a standard initial value. It’s easy to generate and I’ve already tested it on my sample capture data, so that’s good news. Credit goes to Matlo from GIMX

I do have a new version of the UsbXlater hardware that I can get assembled next week. It will emulate button presses on the DualShock 4 directly using electrical signals connected to the buttons themselves, instead of digitally through spoofing data streams.

I am aware that CronusMax has a “proof of concept” video of his hardware working on the PS4, but that video is a fake, what he did is program it to act as a HID keyboard, which only works in the menus. This is why the video does not show gameplay and why he does not plain outright say that it will be supported. Everybody who is making a device similar to XIM or Cronus or Eagle Eye Converter or UsbXlater is facing the exact same difficulties I am facing. I am disappointed in Cronus because the video’s purposes is probably to drive up pre-orders for people who are hoping for PlayStation 4 support which might never come.

I made this thing that converts ordinary headphones into Bluetooth headphones. My laptop and phone both have Bluetooth so this will work great with them.

We turned my phone into a universal remote that uses augmented reality. We can track the location of objects and identify them in real time, so we can overlay an icon representing the object on the video shown on the touchscreen. Simply click on the object to interact with it. It’s all wireless, no base station required.

Actual video is 1080p, I recommend you view it full screen.
