it's power from an external source or the port it plugs into? Some USB devices will exceed the power supplied at the port.
I've just bought a USB 4-port hub. My computer recognised it and installed it, and my memory pen works fine plugged into it, as does my graphics tablet.
however when I plug my MP3 player in, it recognises it, and it comes up in My Computer, but when I open it it appears to be empty, and the software for it doesn't recognise it either. My camera does exactly the same thing, yet they both work when they are plugged directly into the computer. Also, when my broadband modem is plugged into it, the little light in my system try turns from red to orange, but won't go to green.
can anyone offer any help on this? I'd appreciate it.
I don't have high speed USB ports, but the hub says it works on both high and low speeds.
