USB OHCI software

Hi folks,

 are there any software reference implementation for USB OHCI
controllers?

 The microcontroller I'm working on, has an OHCI controller but I
really don't know where to start.

 Basically, I need to read a USB flash disk.

 thanks in advance for any help,

 Enrico

It must be secret microcontroller.

So we can not help you.

You've got a *few* more layers to go after that OHCI HC 
driver ;-) But you asked!

See <http://usb.org> for the standard stuff and think
"Mass Storage Device".

Thanks for the link. It does contain some pieces of code but it's not
a stand alone "OHCI library" :-(

I got a filesystem. I'm looking for an ohci library and the
implementation of some SCSI commad to access the USB disk. The only
OHCI open source code I found is embedded in the Linux kernel. At
first glance, it seems well written but I don't know how difficult
would be extract it from the kernel and compile it as a stand alone
library. Yet, I really don't know how to debug it on WindowsXP because
I think that USB code must be executed as a device driver.

Reference or a product.

We sell a stack together with Sciopta, also there is e.g. HCC Embedded
or On Time which sell standalone stacks.

Look at HCC Embedded, AFAIR they have a stripped down stack for
USB disk.

A reference implementation means 1 or 2 months of my work.
An affordable and reliable product would be interesting.

To read a flash USB disk, a fully fledged HOST library is too much.

Ok, I'll take a look at your product.

Ok, thanks :-)
