Hi, I'm using an LPC2148 (this board), and want to use the USB just to power a device (nothing more). There is a lot of demo code available online for using usb mice etc, but I haven't been able to easily disect which parts are necessary for just turning on the power.
Does anyone have any quick pointers to this information?
So far, I'm selecting V_BUS as the function for pin 0.23 (in PINSEL1) and also setting bit 31 of the PCONP (power control for peripherals register) to "enable USB power".
