USB testing - any more class drivers out there?

The STM32 driver only provides the standard eCos USB API.  On top of
that you'll need to add a USB class driver such as the ones in io/usb.

At the moment, the only applicable one is the serial driver discussed here:

http://ecos.sourceware.org/ml/ecos-devel/2009-05/msg00038.html

I don't know is Simon has had any luck getting it working, but if not
I'll try and put together a patch.

As far as HID support is concerned, eCos is currently a bit lacking in
USB class driver implementations.  You'll need to dig into the
documentation and roll your own.  I'm sure that any standard USB class
drivers you do develop would be more than welcome as contributions!

Sorry, I didn't get it working. But this is more about lack of time and 
priority than anything else. After you have started the discussion about 
how to improve the USB slave framework I thought it may be good to wait 
until we have a better picture and eventually change the USB slave API 
before we adapt the serial driver. But I guess I'm not the only one 
short on time :)

Agreed! If time permits I would like to dig into a standard compliant 
ethernet over USB driver.

I had submit a USB printer package last summer which doesn't seem to 
have made it into CVS. I'm pretty sure it was working.
Andrew: Do you remember why this wasn't accepted?

I also started a mass storage driver, and have it near the top of my 
list for when I get back working on eCos this summer.

I personally never found much use for HID's - unless you're actually 
making a mouse, keyboard, or joystick. I know that most introductory USB 
articles and tutorials show how to implement HID's, but it seems such a 
shame, because others classes, like the serial one, are actually simpler 
and much more useful. So, I probably won't look to implement a HID 
driver myself.

Nor do I think I would start on ethernet over USB myself.

Eval board for testing STM32 USB

[Frank Pagliughi]

Hey Guys,

It seems like it would be worthwhile for me to get an SMT32 board to 
test some new USB code. Make sure it works on a couple different 
targets. Should I get the *STM3210E-EVAL board, or would an Olimex board 
be better?

Thanks,
Frank

I would get the STM3210E for now. It is what's currently supported so I 
think we should build on that.

I second that - I did play around with the Olimex board a while back,
but the device they ship with is pretty limiting.  Plus the STM3210E
board has the external SRAM for debugging using Redboot/GDB.  That's
worth the extra money all on its own!
