ok so this is the question.
setting up the laptop in the garage at home and i need to run cables to the dslr.
1:i use dslr focus so i need to run a usb cable to the dslr remote port so i am wondering is 15 metres going to give me data transmission problems and what kind of cable should i be using .
laptop is an old toshiba so its running a usb interface

many thanks
