I'm I right in thinking its 30Metres?

What about using USB signal repeaters to make a cable longer than 5 meters?

A: Don't bother. The best solution is self-powered hub with a fixed 10m cable that had a one-port bus powered hub in the middle. The maximum range will still have to deal with the timeout, so any out of spec tweaking of the terminations between the two hubs and the timing budget still won't yield more than 5cm of extra distance. A better solution is described in the following question.

So I should be able to get away with a 10Metre run if I use a powered Hub after 5 Metres.

Only thing was probably won't be easy to find a 1port Bus powered hub so would probably use a 4 port self powered hub.

Basically want to connect a usb Device (pair of speakers) thats ~10M away from the Computer

I was always under the impression that the furthest you could go with USB was 25m.

I only want to go ~10m anyway, which if im reading right would basically need a hub after 5m.

Max unpowered is 5m, i reckon you could string hubs together though....

I have used an extender (unpowered) using CAT5e cable and it works over 40 metres.

You can get active extenders from Maplin to take the signal further than the standard 5M without it needing to be powered.

The link I mentioned seemed to suggest not to use USB repeaters.
