USB module questions

Anonymous · Post by **Anonymous** » Mon Sep 17, 2007 8:55 pm

Does the USB module that comes with full version pass the HID Command verifier tests?

The reason I ask this is because I have another compiler that generate code that works, but does not pass the USB command verifier.

Thanks,
Durango

The short answer is I do not know. The Swordfish USB implementation is pretty much a direct port from the Microchip C18 firmware.

David,

Could I ask a favor of you?

Could you please provide a hex file of the sample HID_1.bas that has the PLLDIV set to 2 . I have an EP4 with a PIC18F4550 with an 8MHz clock.
This way I could test to see if tit passes the USB command verifier.

Thanks,
Durango

You can try

PLLDIV is set to 2

David,

Thank you for your example. It passes the HID tests of the USB Command Verifier tool.

Now, to try an get approval for purchasing a license.
If I get one I am sure I will have some more questions for you and the forum members.

Thanks again for quick response and an example.

Thanks for letting me know, I'm pleased it passed. Could you let me know the name of the compiler that failed. I realise you may not want to mention it on the forum, but perhaps you can send me a private email.

What is it you are looking to do? You only need to go through compliance testing if you want to show the USB logo on a product. In many cases, you don't have to go through the certification process. You just need a VID and PID combination and you can sell a product. There is no requirement for certification.
