Re: Implementing a USB Driver

I just noticed the microUSB doesn't have D+/D- pins connected, and the other two usb ports are connected to a usb hub LAN9512. Can I disable LAN9512 and set usb module of BCM2835 to device mode? (through OTG). I have a usb device mode driver ready, and want to test it on raspberry.

Re: Implementing a USB Driver

Can we use that micro-usb port as the device mode usb? Where can I find device mode usb document?
