The Motorola VP22 motherboard used in a variety of modern Agilent’s Infiniium series oscilloscope (the ones with Megazoom) and logic analyzers has a 5-pin USB port that’s not quite the same as the standard headers on\u00a0most motherboards.<\/p>\n

The reason I needed the pinouts of the USB port is because I have a 40-pin DOM SSD to replace the old clunky mechanical hard drive, which needs 5V for power.<\/p>\n

I\u00a0don’t want to modify\/resolder the original wire harness (for the LS-120 and CD-ROM drive) nor I have the molex connectors to make a power splitter.\u00a0Luckily,\u00a0I found somewhere that I can safely tap a 5V for low\u00a0power devices: the internal USB header. Here’s a picture with the DOM SSD module wired:<\/p>\n

This post serves as a reminder to myself that the\u00a0ground is the second pin to the left and 5V is the rightmost pin. The pinout diagram as follow:<\/p>\n
