Hi,

I am tring to develop USB PHDC device stack on beagle board.
We have ported Linux on to it.
But I am not able to find USB (PHY) register, to write /read or other
setting.

Plz could anyone tell how to proceed..whether BSP will provide that.
Low level driver is provided for beagle board.?

Regards,

Did you port a custom distro, or are you running Angstrom?

But I am not able to find USB (PHY) register, to write /read or other
setting.

If you haven't written a driver, I think the device will only show up
in /sys/devices when plugged in

PHDC = USB personal healthcare device class?

If your BB will function as a USB device (that connects to a host) see the USB gadget driver:

You'll also need a compatible driver on the host system the BB connects to.
