RPi include serial port connect RX and TX and GND to Teensy
(

Double check read and write to serial port on simple sketch
I flashed at90usb1286.hex to Teensy++ 2.0
fix port (symbolic link to ttyUSB0)
sudo ln -s /dev/ttyAMA0 /dev/ttyUSB0
and ... "packet header error" "not found adapter" "not found joystic"
help me!

Did you shift the level of the Tx pin of the Teensy to 3.3V?
If you don't do that you can damage the RPi...

I think some adjustments have to be done to allow the UART to work at 500kbps.
Did you remove the ttyAMA0 references in the /boot/cmdline.txt file?

Did you set the init_uart_clock to 8000000 in the /boot/config.txt file?

If you have some time, it would be nice to write some instructions on this wiki page:

Thanks so much for posting this solution! The fewer components needed the better. Hope to make use of it someday

hi guys, I want use an old at90usb162 board (used for psgroove) for emulate a G25 on PS4, I followed the wiki and tried all advises founded around, I can't get it to work and I don't understand what I'm missing..
I'm using a RPI 1 model B, I did update rpi firmware with rpi-update, I did set the init_uart_clock to 8000000 in the /boot/config.txt file, removed the ttyAMA0 references in the /boot/cmdline.txt file, flashed at90usb162.hex to the board, disabled debug messages on the UART port.
The cabling seems ok, when I start gimx the board is correctly recognised, the G25 and the DS4 are correctly recognised too, and if I press buttons on the racing wheel I see from gimx log that buttons are correctly mapped, but simply nothing happens on PS4.
I tried also with a CP2102 usb adapter, cabled to the same at90usb162 board, same results
