Well thing is the chips are virtually identical. Did you double-check the circuitry? I'd still say the code should run right out of the box.
I tested ATtiny2313A microcontrollers programmed on the proven operating the printed circuit board (equipped with a stand under microprocessor) so any error in the PCB is absolutely excluded - the same PCB is working correctly with the AT2313.
Ive loaded up the program (* .hex) using the software AVR-OSPII. Today ive loaded program (* .hex) using the software "mkAVR Calculator" but this change did not bring improvement.
In both cases, after installing the microcontroller, PowerSwitch does not work (Windows does not recognize the USB device)
My programmer is "USB AVR PROG", which certainly supports ATTINY2313 but I have no information about his collaboration with ATtiny2313

Please further suggestions
