Can you configure how it maps the 30+ (?) analog/digital channels in HID to the 4&4 on the OI?

Is the power jack compatible with common battery packs?

Do we have any idea if FIRST will allow an externally-powered device?
The Chicklet is a USB host. Without diving deep into USB protocol, I will say that it will support ALL device functionallity. However one must understand that the device is broken down into two major sections.

1. The USB hosting section

2. The analog/digital interface section

The O/I port consists of 4 digital and 4 analog channels. Apply math and anyone can conclude that it is not possible to interface more than 4 digital I/O if all four analog channels are being used. This is a limitaion of the O/I not the Chicklet itself. However if one were to use a USB joystick, or any other device with only 2 analog channels, the interface can support up to 10 digital I/O's.
