Hi,

I have been wondering about this for a while now. Since USB is bidirectional, is there a way to emulate a usb host in software using the client port on the c860?

I understand that there would be no power supply available on the client port, but this could be implemented in a cable. Apart from this though, what other hardware features are missing from a client side implementation of USB? Is there normally a hardware generated clock signal provided by the host?

The reason i'm thinking of this is that normally it is not conceivable to use a client usb device as a host - but in this case the client is intelligent and not a passive device like a camera, etc...

It's possible that there is 5v power available somewhere in the c860, apparently the c3000 has it on its host port. I like the external solution.... I will have time after May... 16bit microcontroller? What about 14-bit... I have a lot of experience by now programming PICs in assembly (esp 16F877A).
