			<content:encoded><![CDATA[<p>Recently, I ran into a problem trying to install a USB keyboard on Windows XP at work. Given that HID devices always just work with Windows, I wasn&#8217;t quite sure how to go about troubleshooting such a ridiculous problem.</p>
<p>My first step was to investigate the problem, repeating the process to see what went wrong. When I plugged in the keyboard, it would show up as Unknown Device. Searching for drivers would fail. I already had another USB keyboard installed, and this one worked fine. So I tried installing a third keyboard, this time a fancy multimedia keyboard, and it also exhibited the same behavior.</p>
<p>It turned out that my keyboard was not just a Human Interface Device, despite its appearance. It was actually a USB composite device and hub. I spent half a day trying to figure out what was wrong, and ended up learning a lot more about Windows USB driver installation.</p>
<p>Microsoft provides several MSKB articles on troubleshooting USB driver installation, most of which are useless. However, <a href="http://support.microsoft.com/kb/314464">KB314464</a> contains the key to the problem:  setupapi.log. This log file records installations of drivers and the process Windows went through to determine how to match a driver to newly discovered device. Once I opened this file and watched the install fail for the keyboard, it became obvious that it was searching for a USB composite device driver, but not finding one. It turned out my usb.inf was missing. I don&#8217;t know how it got deleted, but it did. Once I copied over a replacement from another PC, the keyboard installed perfectly.</p>
<div id="attachment_9" class="wp-caption aligncenter" style="width: 310px"><a href="http://asyndetic.com/blog/wp-content/uploads/2010/02/lik_devtree.png"><img class="size-medium wp-image-9  colorbox-6" src="http://asyndetic.com/blog/wp-content/uploads/2010/02/lik_devtree-300x236.png" alt="" width="300" height="236" /></a><p class="wp-caption-text">Device Tree for Logitech Illuminated Keyboard (Windows 7)</p></div>
<p>Here&#8217;s what happened with the when I plugged in the keyboard:</p>

</pre>
<p>Windows failed to find an exact driver for the vid/pid combination and tried to find a compatible driver based on the device class. The device is a <strong>usb\composite</strong> device, which should map to a standard Windows driver, but it instead reported that the search failed. At this point, I should have looked for an <em>inf </em>file with this hwid string: <strong>usb\composite</strong>. If I had, I would have discovered it missing in my directory, but present in another machine where I could install a keyboard, in <em>usb.inf</em>.</p>
<p>The <em>Generic</em> <a href="http://msdn.microsoft.com/en-us/library/ms794357.aspx">Models</a> section of <em>usb.inf</em> includes the hwid:</p>
<pre class="brush: plain; title: ; notranslate">

<p>This directs to <a href="http://msdn.microsoft.com/en-us/library/ms794553.aspx">DDInstall</a> sections <em>Composite.Dev.*</em>:</p>

<p>The <em>Composite.Dev</em> section is actually for Windows 2000 and the decorator<em> .NT</em> on <em>Composite.Dev.NT</em> specifies a generic driver for Windows XP and later.</p>
<p>Once I placed the <em>usb.inf</em> file back into the %SYSTEMDIR%\inf directory, installation of the <strong>USB Composite Device</strong> magically worked:</p>

<h3>USB Driver Installation Troubleshooting Steps for Windows XP / Server 2003</h3>
<ol>
<li>Look in device manager to determine the device that failed to install (with a yellow exclamation mark <a href="http://asyndetic.com/blog/wp-content/uploads/2010/02/windevmanager_ye.png"><img class="alignnone size-full wp-image-25 colorbox-6" title="windevmanager_ye" src="http://asyndetic.com/blog/wp-content/uploads/2010/02/windevmanager_ye.png" alt="" width="14" height="17" /></a>)</li>
<li>View the properties to determine its hardware and compatible ids</li>
<li>Search <em>setupapi.log</em> for the device installation and examine the output</li>
<li>If no driver was found, search the <em>%SystemRoot%\Inf </em>directory for the vid/pid or compatible id.</li>
</ol>
<p>In a future article, I will cover the differences for newer versions of Windows (Vista, Server 2008, 7).</p>
