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
We never had problems with the HID example: - MCB2140 Jumpers (VR, DP-, DP+: On) - use the prebuilded object file - download the example to Flash - remove USB cable & JTAG Interface - reconnect the USB (after 10s) Maybe you should also download the latest version 2.40 from http://www.keil.com (just to make sure that you have up-to-date software).

Hello, I have triple checked all the jumpers. I have downloaded the latest compiler and recieved a new Liscense ID code. The CA compiler is V2.32a. I downloaded the zip file again and tried sending the precompiled object file. Same result??? Ok I just tried it one more time with the JTAG(ULINK) removed and uVision closed. IT WORKS!!!!!!!!!!!!!!!!!!!!!!!!!!!! Thanks for everyones help and patience. Now I guess I have to get some real work done, no excuses. Thanks Again, Dave B.
