ti: usb-cable longer than 5 meters?
 

does anybody know a usb-cable that is longer than 5 meters that will work with the ti?
i have my mac in a seperate silent room and so far I only found usb cables with a max. length of 5m so that it only reaches to my desk.
i would prefer to rackmount it but therefor i would need a length around 7-8m.
i allready tried some hubs that didn't work and some kind of usb-extention that was also recognized as a hub.

anybody knows a way to solve that problem?

cheers.
