Game Input MultipleXer

Me again,

Received my FT232RL and ATMega32u4 boards today. Easy setup thanks to the tutorials.

The PS4 registers all of my controls for about 10 seconds then registers nothing all of a sudden. Also, for some reason, the whole log (even when it's registering) is filled with "libusb_transfer failed with status LIBUSB_TRANSFER_ERROR (endpoint=0x84)", yet it still registers controls for up to 10 seconds.

Any help would be appreciated, thanks!

Hi,
I think you have hit the following issue: #345.
If you use a USB 3.0 port for the DS4, try a USB 2.0 port instead.
If it doesn't help, install the libusbK driver and replace the libusb-1.0.dll file, as explained here: http://gimx.fr/wiki/index.php?title=Ins ... on#Windows

Okay, I'll be sure to try that!

But for now there's another problem.
I've tried 2 USB ports (2.0 & 3.0) for the DS4 and board, but it hasn't made a difference.

It started off with me soldering TX0, RX1 and GND on the dev board to keep the header pins in place.
Since then I get the error:

No controller detected.
adapter_detect failed

I've attempted to see if there's power on my 3 pins still by touching either TX or RX from the UART board (while GND is connected) to the dev board and seeing if the LED on the UART board glows. It shows that TX is powered, but I'm not sure how to check if RX is since I believe that is "receive".

Thanks for taking the time to help!

This error message generally means there is a wiring problem or a faulty contact.

Is there any way to test if it is the RX contact on the board?

Using a voltmeter: when both sides are powered and the bus is idle, the voltage level should be +5V on Rx and Tx.

Alright, until I can get a hold of a voltmeter (I don't even know if I can), here's my wiring. I'd love it if you could go over it and make sure it's all correct

It looks good. What's strange here is that according to your first post it was working at some point.

Yep. I think it might have been due to my soldering. However, the solder for the RX pin came off after attaching a jumper to the header. So now the only solder that remains is on the GND and TX pins. I've confirmed that the TX pin is sending power. So I honestly don't know why. If you've got any ideas please let me know, I can't afford to purchase another board.

There's a faulty contact. Re-solder that pin and it should work fine!
