Here is some info on the USBJoy 2.0 Adapter,hopefully this will be next to work...
USBJoy 2.0 is an adapter for connecting the old retro game controllers to your host computer with USB input allowing you to play your favorite games using your favorite joystick or gamepad in either pc-games or older-retro-ones by using various emulators.
In addition, it has a prototype board functionality.
Supported joysticks and pads:
standard one-button or two-button joystick for Atari, Amiga or Commodore (eg. CX-40) Atari CX78 - supported both buttons SEGA three-button and six-button. Sega Master Systems (not tested with the lack of equipment) Nintendo, Pegasus 777, Dendy, Family Game, Super Famicom, etc. - pads with db9 9-pin plug.
Prototype board functionality:
USBJoy 2.0 has small pads for all the ATMEGA-8a pins. Thus one can change the pcb into tiny microcontroller board. Built-in usb-asp programmer makes things easy.
USBJoy 2.0 is compatible with Windows 98 and higher, MacOSX, Linux. It presents itself as a standard HID joystick and does not need any drivers. USBJoy 2.0 will work with every emulator or game that uses OS recognizable HID game controllers
Instructions for use:
USBJoy 2.0 connected to the host computer without any joystick connected will be recognized as a standard 2-button USB joystick. To use other types of joysticks or pads - first connect the pad to USBJoy 2.0, and then USBJoy 2.0 to a computer.
If you connect two USBJoy 2.0 adapters to the computer you will have two-player functionality! Just assign them in the emulator and play with your friend!
The project is based on a project by Raphaël Assénat (http://www.raphnet.net/electronique/atari_usb/index_en.php). Changes from the original is the addition of the joystick CX-78, related changes in the detection of joysticks SEGA, NES pads detection; also, there's the USBasp bootloader installed, so you can upload new firmwares using eg. free software avrdude (http://savannah.nongnu.org/projects/avrdude).
It uses this firmware cos I just reflashed it with the hex file from this site Google Translator has translated it..
