PIC1450 USB Help

Hello, I have run into a problem trying to get the USB code from **broken link removed**. I have got the code to compile and download to the chip, but when I connect the USB to the computer I get a "USB Device not recognized error. I have to create an .inf file and have floundered around for the past two days and I am not making any progress. I have no idea how to create or write drivers and any information that I have found has been way over my head. If anyone has a working example of this chip and the USB driver or can direct me to a tutorial on how to write my own I would appreciate it. Thanks

If you are talking about Jan's genhid code, why don't you spring for a copy of her book? It worked for me. Alternatively you can download the docs from usb.org and don't forget the forum at USB-IF. You might even get Jan to help you.

Thanks, that wasn't the code that I was using, but I will definitely look into that book.

Also the chip that i am using is the 18f2450 not 1450. I don't know how to edit the thread title.

So there was more than one possible instance of "code from here"?. Which one were you talking about?

Enumeration is a fairly straightforward process. You only have to answer a couple of questions correctly and you're off to the races. Why dont you post your descriptors; there might be an obvious error.

BTW do you have a USB monitor? I'm using the Beagle.

Yes, I was using the code for the "Labs". I got the first lab working and am moving on to the second one. I am not sure what happened, but I shut down my computer a few times and it finally installed correctly. Thanks to those who replied.

My problem was the oscillator settings. Now that I have that set correctly I have got all the USB examples running from Microchip, except for the WinUSB example. I can't get the LED's to toggle or get the switch state. The program just freezes up.

EDIT: I am using an 18f4550 now as well

WinUSB sample will freeze if you are not using correct linker script - compare you script with sample code and it will take off.
