I've had the HP-2 for about 60 days. I've been logging hits using Arc Patrol. The HP-2 developed a habit of disconnecting the serial connection at random. Sometimes hours, sometime minutes after connecting. Other times it would not link up at all and Arc Patrol locked up. Windows always detected the com port, Arc Patrol did not. I thought it was an Arc Patrol problem, but after testing various combinations, I don't think it is.

The cause appears to be the power draw from the USB port. The connection is not dropped if the batteries are fully charged. If a USB port sees an excess current draw, it shuts off. I think this is what's happening,

I am searching for a high-charge rate hub that the HP-2 likes. I tried the Pluggable 4-Port with BC 1.1 Charging feature. It will charge, but not work for serial comms.
