Has anyone experienced issues with devices not working on their powered hubs. I have a Belkin 4 port mini hub that I am powering right now with a 5V,2A supply. The DC port on the hub states that it required 5V, 2.1A, but I figured since most of my devices dont require a lot of power it should be fine.

Here is the weird thing, though. I am able to hook up my GPS, CD-rom, and jumpdrive to the hub simultaneously, and they all work fine even WITHOUT external power.

However, my BT dongle and USB HD won't work on it, no matter what, even if they are the only devices connected. The lights just don't turn on, indicating that there is not enough power. The USB HD still has one connection to straight to the pc for extra power, but if I connect its data cable to the hub, it won't work.

I am using a 4-port USB 2.0 PCMCIA card in my computer as my main connection. Everything works fine (including the BT dongle and the HD) if connected directly. Any help would be appreciated.
