What i mean is that you might need a USB host controller in order to connect USB devices to it (PC brings one), with PIC micros you can only make devices to be connected since it doesnt have the host controller, so you can't connect a USB mouse to a PIC and expect to receive the data.

On the other hand it would be really usefull to emulate someway the controller behavior with the pic since you can find tons of ideas where a USB device is controlled by a uC. I am just considering USB cameras(cheap), uSB keyboard, MOUSE, USB memory for storage, etc. I had this same question in the USB demo by mister_e asked sometime ago, someone there proposed a small device that could be used to control USB things but it was external and far away from Colombia and Chile .

'Hola' Josuetas,

Well, capturing USB mouse data into a PIC is just what i'm wondering to get, and it's just what I'm going to try to do as I get back in afternoon into my home-lab.

Since mouse is only UNI-directional (luckylly much simpler than your link) and this is my really experiment- i'm trying to intercept, to capture data before it gets into USB layer, not as USB data, just as some standard (serial?) data thread from PIC to PIC (mouse to PIC) as to communicate with some kind of HSERIN or something by the kind/style. Theese are just raw ideas maybe just dumb but that's just what I want to prove and test if possible or not.

Maybe all this is an obvious and simple thing, or just an impossible idea...
I don't know why but I fell optimistick about this. I want to run home just now to experiment.

Any suggestions/ideas be welcome

regards,
RodSTAR
