USB extension cables

[Olsin]

Hi ... I would like to be able to connect my DSLR camera to the telescope and run it from my computer which would be approx 3 meters awway. I use digicamcontrol to remote view the camera on my computer.
Does anyone know if a 3 meter USB extension would work, or would there be to much resistance over that length?
I haven't been able to find any information on this on google although i may be keying in the wrong search parameters.

I should probably also state that i don't actually have a scope at the moment. I'm just trying to get a few things ready for when i do get one.

I shouldn't have used google!

I indirectly found the answer to my question along with ideas to alternative solutions in this thread..

From what I've heard, the general maximum length is 5 meters. Anything longer than that and you need an Active Usb extender cable. I got one of those, which is 10 meters going from my DSLR to my laptop, and it works perfectly.

I have used my Canon 550d with 3m & 5m extension cables without issue.

In the end I bought a 5m USB cable with the correct mini USB connector for the camera, so no extension just one long USB lead.
