USB stream

i be in heaven if p5 had an easy way for me to access any USB device i wish to connect to.
I don't know how complicated the issue of device connectedness is, but there're a huge range of possible devices out there that are not webcams. even if the degree of integration was on a basic bit-stream level (or especially so), i would relish the opportunity to examine the ways that devices communicate through the USB port, through p5.

Look in your registry under HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Enum/HID - it shows all the connected USB HID devices, listed by VID and PID (in hex).

(Also, look at he 'USB' directory under 'Enum' for a list of non-HID devices).
A word of note - if a device is currently being used (your mouse, for example), then you won't be able to access it.

Is there any way to do this without making a "pic chip" for your USB device?
