Lemme see if I can find the thread / pictures.

Thanks for the pics.  That was the one.


I think what you are saying is different then what you are asking for.

You are saying you want to use a USB cable instead of ethernet cable, etc.  Well if that's true just chop off both ends and wire it up. No big deal.

I think what you want is a USB enocder.  The part you want modular is the USB cable instead of how you have it now, ie the button, etc connections are modular. 

You'll need a seperate encoder for each panel.  Is this what you were talking about?
mahuti:
If I have to do it with 1 encoder per panel, that gets expensive, and may not work anyway.

I'm trying to just keep each panel down to 1 connection, and I like USB cables, so I'm idly curious about using USB cables as a connection. I could get into the specific reasons why I want to use USB cables, but it's not that important.

The problem with just cutting USB cables... I didn't think they were color coded on the inside, so using them to make multiple swappable panels would be difficult. I thought there might be some kind of cheap pre-coded cable or usb interfacing board or something out there already made that I don't know about.

USB Cables are color coded Red, Black, White, and Green.

Just while we're on the subject...does the outer metal screen need to be connected up (if it even has one in the cable itself)?

Well, the answer is a firm....it depends. 

Technically, It isn't a requirement for the system to work and it will probably be fine without it.  It is a shield used to block noise on the power, gnd and signal lines.  Some enclosures will have more noise then others.  Also, I think most of the USB devices are low speed so that may help, High-speed and Full-Speed devices would be more susceptible to noise.  Not having a 5 meter run to the PC would help and having a short run after the modular part would help.  I definitely wouldn't do it for a removable hard drive, but for this application it probably will be fine.   Make sure the shield doesn't touch any other wires.

I'm more worried about not attaching GND first, but I have a really low threshold for this.  I should probably get off my soapbox for this, but my customers are really dumb.  ::)
