Our partners have recently tested Artec Eva with this cable: Delock Cable USB 2.0 Extension. They used 5-meter cable in their experiment and reported that everything was working well.
We've tested the 10-meter and 20-meter Delock USB extensions, and both of them appear to be working well (we tested both Eva and Spider with this configuration). We tried to combine these two cables into 30-meters one and again, both scanners were working well.
Artec clients from United Kingdom have also reported that everything worked great with this 5-meters cable (USB 2.0 A to A Active Extension Cable).
