Question: i am trying to figure out how to convert a .jar minecraft file into Ubuntu-friendly. the problem is, that Ubuntu does not recognize java.

Answer: 
I was able to get my Gamdias Hermes Keyboard to work on my Linux desktop which is using Ubuntu Mate but I believe it will work will all forms of Linux distributions. I Want to make an application to run at startup to get it to work but I am personally unable to make it.
But the fix I was able to find is.

```
Sudo cat /dev/usb/hiddev#

```

You also need to press some keys on the keyboard to make sure it is the keyboard but if it is it will 

This will require you to use a separate keyboard or mouse and a few tries to figure out the number of the keyboard but in all it has worked for me every time I find the right file.

*You will need to do this command at every boot*

Good Luck
I found the v78 firmware on Gamdias FTP Server at <ftp://ftp.gamdias.com/gamdias/HERA_extension/keyboard/HERMES/GKB2000_2010_Linux/> . Unpack the FWUpdate-75&78.zip, run HermesUPDATE and select HERMES\_ap\_2014\_04\_18\_78.hex file. This will upgrade the firmware to v78 which works with Linux. This keyboard is great, I use it on Arch Linux.
