Hi, The real problem is capacitance on USB wires. Long story short: the USB cables should be short as possible since USB working at 12 MHz (at least USBasp). Also 12 MHz crystal should be very close to AVR chip. Long wires make troubles :) Regards Martin

This schematic should have just the CPU, a couple of wires to USB and a few (4) wires going to the target. Together with two zeners and a two resistors, I expect about 12 wires in total. I'm seeing about 3 times too many. Roger. -- ** [email protected] ** http://www.BitWizard.nl/ ** +31-15-2600998 ** ** Delftechpark 26 2628 XH Delft, The Netherlands.
