I though this maybe usefull for some of you. USBwiz alows you to 
connect your AVR to almost any USB device (mouse, keyboard, thumb 
drive...etc.)

http://www.ghielectronics.com/USBhost.htm

Is it possible to purchase the source code?

Atmel has an app note detailing how this works.

Hi All,

I'm trying to find information on any IC's that can interface to a CCD/CMOS
camera chip and display its output on a LCD/TFT panel 
(for view finding purposes) 18fps would be great ... I've located some chips
from a company called Sunplus but it seems that they are not selling to
anyone not willing to purchase a boing 747 packed with their devices I'm
looking for something very integrated, price is really no issue but quantity
of purchase should be around 100-500 devices.

Any info?

Regards 
Lasse Madsen

That's not the same thing at all.  The Atmel app note discusses 
turning your AVR into a USB _peripheral_, whereas the GHI chip acts as 
a USB _master_ -- a considerably more complex undertaking (although 
just getting the AVR working as a USB peripheral is a pretty 
sophisticated undertaking too).

I'd like the GHI part a lot better if the pricing were more like $10-
$15 per chip (less than the current $35-$40) and the binary image 
license was, say, $10k (more than the current $5K) instead.

USBwiz is a host not a device. It actes like your PC NOT the thumb 
drive. it also includes FAT stack. 

So you have FAT and USB (_HOST_) on one chip

There is no plans to sell the source codes yet but you can purchase 
a library license. Details are on website.

We are also going to add interpreter that runs with USB and FAT. 
This way you can do whatever you want from your own code that runs 
on USBwiz

If you only want to talk to USB-memory sticks, the host implementation part 
is
pretty simple. A lot of the regular chit-chat that set up the USB link can 
be
skipped.
I've tried this with a EZ811 chip from Cypress, which is supersimple to 
interface
to the AVR. (sorry, no code is available at the moment).
They have a Powerpoint presentation somewhere on their site, showing how to
shave off the unneeded stuff.

The reduction in complexity should work with other device classes too.

Yeah, I liked the USBwiz a lot.  Any idea when they'll
have 802.11b/g?

Hi Jesper,

By the time you get as far as having all the code to read and write 
FAT and FAT32, I'm not sure if I'd call it "simple" anymore -- we're 
talking thousands of lines of code!  But I agree that getting USB 
talking to a single peripheral is significantly simpler than a 
general purpose USB stack.

Unfortunately, I've been told that even some memory sticks (in 
particular, some made by Sony) contain embedded hubs so that they 
can present multiple devices (e.g., the "memory" itself as a mass 
storage class device, and then a proprietary encryption device or 
whatever); I would be pleasantly surprised if the GHI chip worked 
with such 'sticks.

I know for a fact that those cheap ($29) "plug into the cigarette 
light MP3 players that read a USB memory stick for data" don't work 
with a Creative Labs Muvo memory stick/MP3 player/FM radio (that, on 
a PC, does just end up as a "disk drive").  I haven't taken a look 
at how the Muvo presents itself on the USB, but I wouldn't be 
surprised if it's a similar problem.

Thousands of lines ? Not at all. I've been working with FAT for years,
and it's not that complex.
I even have a FAT capable bootloader in a mega8 ! About 750 bytes
complete with CF card driver, programming and support routines.

And the USB enumeration and handling is also really small. I haven't
cleaned up the routines, but when it's done, I'll report on the sizes.

/Jesper

a reliable FAT 12,16 and 32 with read and write is a lot of code. I 
don't what you are talking about but with our optomized code it is 
about 50K flash and 5K RAM

adding on USB is another 50K flash and mass storage class is another 
30K!!!

My FAT16/FAT32 read/write system, with directory and long filename
handling is about 10-15K including fopen/fclose e.t.c. support.

I'm pretty sure my handling of USB memory sticks will be less than 5K. 
This is obviously not full class support by the book, but it will handle
>95% of the thumb drives out there. That's what counts for me.
