Really Annoying Buzzing, Why has it all gone hideously wrong? Options

[bobstermarley]

Just been in to do a spot of tinkering and flicked everything on and got a really irritating buzzing noise coming through my speakers.

Have managed to isolate it down to the MobilePre USB interface suddenly not liking the Belkin USB hub or rather, not liking the power supply being connected to it. The MobilePre USB works fine when the hub is switched off, but when it's on, I get the buzzing.

It's only just started doing this, so I flicked everything off and on again. Now ALL of the lights on the Belkin hub have gone off and it doesn't seem to be working at all. In short, I think my USB hub has died.

As you can see from my gear list, I'm running everything on a PowerBook, so USB ports are not exactly plentiful (there's only 2 on it) so I need a USB hub to get everything up and running.

Has anyone got any recommendations or suggestions for a nice meaty USB hub worth investing in to sort out any current issues with the MobilePre USB and also for any future gear I might invest in and need yet more USB connections? Surely I can't be the only person in the world who needs more than 4 USB ports?
