Use a Blackhawk BH-USB-100v2 controler on Arduino Mega?

I have a BlackHawk BH-USB-100v2 that is designed to connect to a TI JTAG port.

I see some posetings listing a JTAGICE, and Dragon.

Are all JTAG controllers interchangeable?

Can I expect to be able to use the BlackHawk on my Arduino Mega?

As far as I know, the interface signals are "standardized" Is this true?

Also, if someone has experience with this configuration, I'd like to know.

Thanks, Mark.
