libprs500 did not seem to copy right, I deleted the egg files and ran setup.py from the tarball in the first post and it worked again.

so, I went back to that and got the USB prober working. more happens than the system logs led me to believe. first it looks for drivers, some of these it tries several times.

at first I was thinking this happened when your program tries to connect, but i investigated more and found that it does the same thing when the reader is plugged in. so this is likely caused by the reset that occurs.
