A quick note to mention that my usbtiny v. 2 has gone together flawlessly, and after a bit of fiddling with the makefile, it got winavr to blink an led connected to my breadboarded attiny45v. Hurrah for ladyada's inexpensive programmer!
Newcomers might be happy to use http://imakeprojects.com/Projects/avr-tutorial/ as a source of simple code. Also, note that if you use WinAVR, you should use the makefile template at mfile/makefile_template. I found the one at samples/Makefile didn't do it for me. Finally, don't comment out the AVRDUDE_PORT assignment statement in the makefile, even though 'dude doesn't care about that value if you're using usbtiny. Leave it as com1 or whatever.
Thanks to all who contributed to this forum and from whom I read before undertaking this project.
