</p><dl class="margin">

<dd><ol class="List2"><li value="1"><a name="85253"></a>
Make sure your target board is Revision C or later. To ascertain your revision status, check the artwork on the bottom/backside of the board, next to the bottom ejector. For example, if the revision number is 84-W8288F01C Fab Rev A, it is the "C" that follows the 84-alphanumeric that indicates the revision.</li></ol>
<dd><ol class="List2"><li value="2"><a name="85254"></a>
Use a boot ROM that does not include USB in the exclude list. To do this, in the <b class="routine">sysPciAutoConfigInclude(&nbsp;)</b> routine in the <b class="file">target/config/mcp750/sysBusPci.c</b> file, change the return value of the <b class="symbol_UC">PCI_ID_USB</b> case from ERROR to OK.
