I can NOT get this example to work? I have been using the MCB2140 for several weeks, no problem there. I can open the HID project in uVision3, compile it, download it, run it, step thru it. Then I remove the USB cable , wait 10 seconds (yes, I read and followed the instructions), plug the USB cable back in and my PC (running XP) says "USB Device Not Recogonized" When I go into the device properties, the Device status is: " No drivers are installed for this device." Has anybody else had this problem? Am I missing something obvious? I did not modify the HID code at all, should I? If anyone can pass along ANY kind of hint, tip or otherwise useful information, I would really appreciate it. Thanks, Dave
Dave; This does not address your question directly but it will help you complete your project. As Dan Henry has pointed out is the forum, http://www.usbee.com has an excellent tool for debugging serial/usb comm of this type. A scope is great but in your project you will need to record a data stream over several seconds. I have this tool at one of my customers. It has saved many hours of head scratching. Good tools don't cost, they save. No. I do not sale any tools. Bradfrod
Al, Thanks for the suggestion, I can't believe I've never been to this site before. It looks like really good stuff. I will be reading frantically today. Thanks, Dave
