I'm building a sort of mini "docking station" for my C1000, which will supply power and have a USB hub. I need a short USB OTG mini-A to mini-B cable for connecting the Z to the hub. This type of cable does not appear to be very popular and the shortest I've found thus far is 1.5m. 15cm (6-in) would be more than enough for my purposes and I don't want loops of extra cable hanging off.
Does anyone know of a source for something like this? I could custom order, but the min order for one site I found is $100 and I doubt I'll find another vendor that's much cheaper.
If this cable does not exist, would it be practical to build one? I'm not familiar with USB cables or if there are tight specs on the type of conductors, shielding, etc.
