Beagle to Beagle USB Connection?

Hello All,

I'd like to transfer a data b/w two beagleboard using the USB cable.
I know there's a way transfer data with RNDIS (USB/IP) however the
transfer speed was not satisfying.
Is there a way to transfer a data using the USB OTG to USB b/w two
beagleboard (One as device and another one as Host)?
Have anyone done it? Could anyone tell me how?

Best Regards,

Some OTG validation tests for both host and device modes are here:

The data throughput will depend on the USB transfer type (bulk is fastest) and the performance of the firmware on the host and device.

Hello again,

This is what I did to connect two BB using the OTG to USB cable.

One as a device (no external power supplied, connected to host while
holding down user switch/button)
One as a Host (external power supplied)

I get following error when I connect device to host and the device
(BB) is not recognized on the host side.
