Hey guys... 
I am new to the USB thing, and I need to develop a USB HID host
software. My USH HID device can send any random data (of any size).
Firstly, how do I map it to report descriptor ? Secondly what will my
host do with the received report descriptor</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: USB HID - What is the use of report descriptors ?</title><link>https://community.arm.com/thread/67030?ContentTypeID=1</link><pubDate>Sat, 29 Oct 2011 06:16:37 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:69867eea-dd34-4610-9b2c-1dc06f2b1723</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
So send as many 64-byte frames as you need, followed by an empty
or partially filled frame when you have reached the full size of one
of your &amp;quot;records&amp;quot; of random data. Unless you enumerate your device as
a standard device your PC can handle using the standard drivers like
a keyboard), the PC will not care about the contents of the data - it
will be up to the driver, or the program connecting to the driver, to
figure out what the data means.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
