HELP: USB Debug Mode not working Anymore

This happens today as i am debugging a little program of mine. Suddenly, the device stops from being recognized on both macs and Windows. At first i thought the mini usb connector was faulty however, i connected the cable and it shows that it's charging. However, when i do ADB devices.. still no devices found.
Can anyone provide a solution to this?
Tried enabling usb mode on and off, restart PC and mac. nothing works.
Thanks.

What rom use....? Stock or dev. ????
If your dev. rom ....you should off the debugging

Did you disable MTP at startup? Most people commit this mistake.

Just to be on the safe side. Have you checked using another computer?

I cant try it on another computer right now :/
I got new cable and still when connect it via MTP i got information from PC suite i dont got this drivers :
http://www.microsoft.com/en-us/download/details.aspx?id=19289
But i cant install them... like i said “this update is not applicable to your computer”

And another info : when im trying to instal MTP drivers via lg pc suite i got error, even if device is disconnected.

Okey so on another computer also on windows 7 x64 usb connection working fine, so what the F... is the problem here?
