I'm thinking to use a DB25 connector to replace 2 USB connectors + 2 power supply connectors. Basically 8 pins for USB, 2 pins for 5V & GND, and 2 pins for 12V & GND (4A).
This way instead of 4 connectors, I only have one.
First questions, will USB communication get interfere by the powers (5V & 12V)?
Also, I'm planning to do a dual DB25 connector(one 90 degrees connector and the other normal parallel port connector).
Question is: When one end is connected, will the other end pick up noise on D+ & D- of the USBs (DB25 male connectors;therefore, the un-use end kind of acting like an antenna)?
Thanks in advance.
