Here is a cut n paste from a DSI Imager forum for the benefit
of DSI users. I can't validate any of it's claims, purely a heads up:

For members in the US, OPT has Meade 15' USB cables for the DSI on sale
for $18.00 and free shipping (shipping is till midnight Jan 10th, not
sure about the sale).

This is a great deal for these cables as the DSI cameras need ALL the
power they can get to operate properly. With a 15 foot long cable (16
feet is the limit of USB 2.0 spec) the USB cable MUST have a 20AWG power
lead.
It's REAL difficult to find a USB cable this long with a 20AWG power
lead, and near impossible to find one for this price. If you are using a
USB cable longer than 3 feet on your DSI camera, look at the what is
written on the wire. If it's says "28AWG/28AWG" or (more commonly on
longer cables) "28AWG/24AWG", the second number is the power lead and if
it is less than 20AWG you may have intermittent problems with your DSI
(especially when it gets cold).
