<pre wrap="">Hi Alberto,
Happy to hear your getting into WinUSB. In the long run this is
probably the right thing for Windows platforms.

Hi Bill,<br>
<br>
yes, and for me it is a good way to learn something about USB <span

<pre wrap="">I think the endpoint count does not include the default ep0 control
endpoint which is the only one configured by default when the FX2 on
Ozy is repowered. For info on the default configuration of the FX2
after power up take a look at chapter 3 of the Cypress FX2 tech ref
(<a class="moz-txt-link-freetext" href="http://www.keil.com/dd/docs/datashts/cypress/fx2_trm.pdf">http://www.keil.com/dd/docs/datashts/cypress/fx2_trm.pdf</a>). One
(admittedly tedious) thing you could do to see if your WinUSB code is
doing what you expect is to load Ozy with the existing libusb base
code, uninstall the libusb based driver, unplug the USB cable from
Ozy (leaving Ozy powered so the firmware stays loaded). Plug USB
cable back in - tell Windows to use WinUSB based driver now and run
your code. You should see 3 endpoints at this point.

YES ! Doing what you suggest shows 3 endpoints configured... this is
much reassuring, <br>
as it means that, at least up to this point, the code is working
correctly.<br>
<br>
I will read all the suggested docs, I just wish one day Micro$oft could
learn to make things simpler....<br>
I am sure that many of the 'software architects' there, when they need
to scratch the right ear,<br>
they use the left hand, passing the arm over the head...<br>
<br>
Thanks Bill, and, rest assured, I will have many other questions in the
future about USB... <span class="moz-smiley-s1"><span> :-) </span></span><br>
