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.

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

Thanks for the suggestion, I can&amp;#39;t believe I&amp;#39;ve never been to this site before.  It looks like really good stuff.  I will be reading frantically today.&lt;br /&gt;
&lt;br /&gt;
Thanks,&lt;br /&gt;

This does not address your question directly but it will help you complete your project. As Dan Henry has pointed out is the forum, &lt;a href="http://www.usbee.com" target="_blank"&gt;http://www.usbee.com&lt;/a&gt; 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.&lt;br /&gt;
I have this tool at one of my customers. It has saved many hours of head scratching.&lt;br /&gt;
Good tools don&amp;#39;t cost, they save. No. I do not sale any tools.&lt;br /&gt;

&lt;br /&gt;
 - MCB2140 Jumpers (VR, DP-, DP+: On)&lt;br /&gt;
 - use the prebuilded object file&lt;br /&gt;
 - download the example to Flash&lt;br /&gt;
 - remove USB cable &amp;amp; JTAG Interface&lt;br /&gt;
 - reconnect the USB (after 10s)&lt;br /&gt;
&lt;br /&gt;
Maybe you should also download the latest version 2.40 from &lt;a href="http://www.keil.com"&gt;http://www.keil.com&lt;/a&gt; (just to make sure that you have up-to-date software).&lt;br /&gt;

&lt;br /&gt;
There has been some trouble reported with the mass storage example, but not the HID example.&lt;br /&gt;
&lt;br /&gt;
My main PC as I stated in my initial post is running Windows XP.  I have also verified the same behavior on a different PC running 2000.&lt;br /&gt;
&lt;br /&gt;
This is my first attempt at using USB, so I was really hoping to get up to speed using the MCB2140 and this HID example.&lt;br /&gt;
&lt;br /&gt;
I&amp;#39;m really not sure where to start here.  I guess I need to start probing the lines and looking at what actual data is being sent back and forth?&lt;br /&gt;
&lt;br /&gt;
Thanks,&lt;br /&gt;
