John,
While working with BricxCC on a spybot project (still not done) I
encountered an odd situation.
1st) something happened to the comm port that the spybot cable is
connected; I couldn't send or receive (or detect) the spybot.
2nd) Using the autodetect feature, it detected the spybot through the
USB tower (that happened to be face down on the table a couple feet away!)
3rd) I was able to download programs to the spybot through the USB tower.
Is this what you are referring to (program -> USB Tower -> spybot)? It
seemed to work just fine for me.
