Query: You can't use 2 of these at the same time.

I had one of these, and was planning to add another to my system (which does have two separate USB hubs). My Windows XP computer can only recognize one at a time. I talked to Tech support, and the guy actually suggested that I buy a different brand. I wish I had bought a Maxtor One Touch. Don't buy this.
