I see a number of high-end gadgets and cables that promise improved SQ, lower jitter, lower noise, etc., by injecting external 5v power into the cable, replacing the dirty and noisy 5v supplied by the PC. Seemed to me that this should be an easy DYI project, so I went ahead and spliced an off-the-shelf USB cable, severed the 5v power lines coming from the PC and connected an external jack that now accepts an external power supply. This enabled two experiments. I could now try a better regulated 5v power, including an LPS, or, I could try to see if my digital devices don't need power altogether by not plugging in external power. The cable works, as I have some USB gadgets that run on the USB-provided 5v that work correctly, and some data-only gadgets that also work, even without the 5v. Except for one device. Has anyone else tried such a project, and what did you find? Any suggestions or recommendations on what to do or not to do? When the cable (and the device) work, the sound is improved. But, I have one device that refuses to recognize the cable, with external power or without it. As long as I have all four wires and the shield connected all the way through, this device works. But, with my modded cable, the PC never recognizes the device. Any ideas why?
