hi all:

I was using my activity board for several weeks now w/o any problems. All of a sudden the board is not recognized on com port 10. Tried re installing the USB drivers from Parallax web site but no go. What is going on? Very frustrating. Using Windows 7. Thaks

    What are you powering your board with? If you are using batteries, are they dead? Did you try another using USB cable? Does the com port still show up in the list?

    Using USB cable. The com port 10 shows up in S IDE . The robot works normally when powered by a battery and a program loaded earlier into EEPROM . This should indicate the prop chip is ok? Tried reset switch several times but no change.

    Your propeller definitely works, then.

    Can the Propeller Tool identify your board?
