I am new to the USBasp. I am trying to program a Mega1284.
I have a cheap Chinese one, it is recognized in XP as well as win7. I made a board with a ZIF socket, 10 MHz xtal, 22p cap, 10k pullup on the reset, external power and 2x5 pin header. The requisite connections to the header have been made (MOSI, MISO, SCK, /RESET).
No luck with Bascom AVR or extreme burner. Anything in XP tells me no USBasp device found, device manager sees it and it quite happy with it.
In win7, the same efforts just yield a failure to communicate with chip message.
All different drivers have been tried as mentioned over and over in various places. No luck whatsoever.
I have the power jumper on the USBasp open as I am supplying my own power to the mcu.
I am guessing I have a junk programmer. Anyone have any thoguhts to the contrary?
