    Check fuse bits, 0xCF HIGH and 0xFF low should work well. Also i have reprojected PCB (by mi), as small as it can be :D I'm including PDF and eagle PCB files :D. Note that analog GND should be separatly connected to main GND by chooke

    Chceck zener diodes and resistors at usb data lines, i looked at picture, mjoy 16 remains Atmega16/Atmega16A, set cokpt fusebit (0). Lets try my version of pbc, 1 link up, its smaller and it work at 100% :D

    Hi!
    For Mjoy16 you have to use a Zener diode 3.3Volt, 0.5Watt, not higher Watts! Earlier I biult an MJoy16, very accuratly, but it did not work, "Not recognised"... The only problem was:I used 2Watts zener!!! I changed it (all 2 of them :) ) and now it works fine!

    FYI - Since Mjoy/Mjoy16 is now obsolete (USB 1.1 - low frequency), a cheap Arduino PRO micro provide a better solution (USB 2.0, high frequency).

    Firmware for joystick already available, the Mega_Mozg MMjoy: http://simhq.com/forum/ubbthreads.php/topics/3899105/MMJoy_-_Build_your_own_USB_con

    Is not cost effective - besides difficult due the SMD format of ATMEGA32U4 - but PCB layout for DIY assembly is available.
