USB host

Hi everyone,

we are electronic designers and we want to read/write USD Drive keys in an
electronic controller produced by ourselves. No standard Operating System
(e.g. WinCE, Linux etc.) is used. We want to develop the function in our
private firmware to read/write your USB Drive Key but we don't know how it
works. We studied the USB 2.0 specifications overview but we believe that
generic USB specifications are too wide for our purposes; we think we can
use a small subset of commands.

Can anyone help us ? Every kind of suggestion is welcome !
Is there someone that has developed an USB host on an embedded controller ?
We need ONLY to read USB drive keys in place of floppy disk.

Thank you.

Alessandro

Have you heard of a thing called Google?

No, what is it ? :-)))))))
It's just several day that I search with google and I find and downloaded so
much documentation that my brain realize nothing. I'm only looking for some
suggestion to better refine my search.

Several Silicon manufacturers sell development kits for their USB chips
wich include software examples. Philips, Cypress and CYgnal(Silicon Labs)
to name a few.

Look at Atmel's host part, which has built-in firmware to do the
mass-storage support for you.

I used an SL811HS on a PIC 18F452. Took a couple of days to port over
the parts of the Cypress 8051 C code to CCS. I can now talk to the
hub, memory and wlan key. Only problem I had was the clock on the
SL811, I tried a 12 Mhz Xtal, but had to change to a 48Mhz oscilator.
Not USB2 , but good enough for embedded.
I now feel I was afraid of USB for too long

Alessandro,

On Time's RTUSB-32 http://www.on-time.com/rtusb.htm is a portable USB host
stack for USB 1.1 and 2.0. To operate USB mass storage devices, you would
also need a file system. On Time's RTFiles-32
http://www.on-time.com/rtfiles.htm together with RTUSB-32 supports all USB
disks formatted with FAT-12/16/32 and ISO-9660 file systems.

Why not to look at the linux drivers to have ideas for your implementation ?
