USB Flash Drive OR Simple USB Programming ?

Areal Person

Hi,

I've been reviewing the wiki on USB
http://en.wikibooks.org/wiki/Serial_Programming:USB_Technical_Manual

Things like
"USB signaling" look simple. Looks like it would be easy to use things like
'device descriptors" etc...

maybe I should look at the Linux kernal source for the USB host controller
and see how it is implemented in general ?

USB support for the Propeller ? Hummm....

QUESTION:

How hard would it be to implement a basic/simple routine for the Propeller
that could use a small USB flash drive for some memory storage kinda like a SD card.

Why would this be difficult ?

I would like to make a simple PDA with my Propeller chip, It would be nice if it
could use simple USB in general.

Maybe I could start by making a simple USB "Sniffer" that would read and decode the
data stream from the host controller to the device(functions).

What do you think?

What you want is a usb host which appears all but impossibly to implement on the propeller. There are however a couple of companies that make usb host chips that you could use. I think vinaculam makes on and so does ftdi. There was some discussion about it in this thread http://forums.parallax.com/showthread.php?p=675656
