Clone of AVR JTAG ICE , USB version

[gres]

It's a project of debbuger that first version you can find at **broken link removed** My project is tune up to use by USB. I reach that thanks to removing original MAX232 conventer and replace by USB>RS conventer. I used conventer that works in mobile phone cable. It's a Prolific PL2303, system see it as a normal serial port.
List of processes is impressive, mainly becouse processor has JTAG. That's why you can't use so popular mega8 or tiny2113. Very good option is to make all projects for mega32 and then convert to smaller processors - advantages of C language.
List of works systems:

ATmega128, ATmega128L, AT90CAN128
ATmega16, ATmega16L
ATmega162, ATmega162L, ATmega162V
ATmega165, ATmega165V
ATmega169, ATmega169L, ATmega169V
ATmega32, ATmega32L
ATmega323, ATmega323L
ATmega64, ATmega64L

I refuse DC-jack connection, programmer and system can be powered by USB port, secure by polymer fuse for current 0,2A.
Second power possibility is via JTAG, then all programmer is powered by this port except converter - still by USB. Power choose by jumper. Possibility of choosing power source is important when debbuging system is powered by another voltage then 5V or debbuging system need better current efficiency then 0,2A. My system is with mega16 instead mega16L, so I can't debbuging systems more than 5V. It's only because I couldn't find L.
Casing - none. I thought that author designed his board for some casing so my board has the same dimensions.

thanks for the info
but
i cannot understand much info from ur links as i think they are in russian language.

it will be great if you can give some more info from these links in english.

i am in gsm , so i like to know more about this, as i get many phones with boot erased, means cannot communicate with standered flashing(downgrading-upgrading)soft.

can ur project help in this problem. as i knew with jtag interface we can revive such phones.
