Is it possible to use an ATtiny45 for either the xmitter or receiver?

That’s because a lot of V-USB projects use goofy things like LED’s instead of diodes, or crazy resistor voltage dividers. All you need to do is use 3.6v zeners and clamp the data lines to ground. For clarity, stripe of diode to data line, other end to ground. That is IN PLACE OF those stupid LED’s (LED 1 & 2 on the schematic, and yes, reversed orientation than shown, STRIPE to D+&-). I had to make a modded USB cable with the zeners going to ground to get the pocket programmer to work in linux.
And yes, I know an LED is technically a diode but it is NOT a Zener diode, which is more standard USB circuit design (or, at least was, now we got FTDI and USB enabled mcu’s). Josh, I’m willing to bet that mouse is reallllllllly cheap? :)

I was doing the HelloWorld example from http://my.opera.com/CrazyTerabyte/blog/2007/10/25/first-contact-with-atmega8-microcontroller-part-1 and the Atmega8-16PU would not flash with the “-B 1” flag. Is it used only when using an external crystal?<br />
And could someone please explain the “Power Target” switch? Which setting is to supply the circuit and which setting is to use external power source?
