Hello,&lt;br /&gt;
I&amp;#39;m implementing USB mass storage device on LPC2148. My device is now
detected but the properties show RAW data format and when i try to
open or explore the drive i get error &amp;quot;Your device should be
formatted&amp;quot; if i click on Yes it again gives error &amp;quot;The device cannot
be formatted&amp;quot; . So i want to convert the data on my device to a
format readable by Windows XP so which format i should use? From
where to start? From where i can get code for it?&lt;br /&gt;
are such codes available? How they can be implemented? I don&amp;#39;t want
to use SD card.&lt;br /&gt;
Ya and which system would you suggest FAT or NTFS?&lt;br /&gt;
Thank you.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Interfacing LPC2148 to PC through USB</title><link>https://community.arm.com/thread/102045?ContentTypeID=1</link><pubDate>Tue, 26 Jan 2010 08:33:44 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9377c903-a3b8-4237-87d9-7662f38a0487</guid><dc:creator>Tsuneo Chinzei</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;&amp;gt;we used usblyzer software but its not detecting the
device.&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Did you apply &amp;quot;automatic capture of hot plugged device&amp;quot;
feature?&lt;/p&gt;

&lt;p&gt;
Or try SourceUSB with &amp;quot;hot plugged&amp;quot; feature.&lt;br /&gt;
&lt;a href="http://www.sourcequest.com/"&gt;http://www.sourcequest.com/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
SourceUSB misses the first Get_Descriptor, but it catches next
Set_Address and later sequence.&lt;/p&gt;

&lt;p&gt;
1) bus reset&lt;br /&gt;
2) Get_Descriptor( DEVICE )&lt;br /&gt;
3) bus reset&lt;br /&gt;
4) Set_Address&lt;br /&gt;
5) Get_Descriptor( DEVICE )&lt;br /&gt;
6) Get_Descriptor( CONFIG )&lt;br /&gt;
...&lt;/p&gt;

&lt;p&gt;

&lt;p&gt;
As of the original post,&lt;br /&gt;
It&amp;#39;s the same problem as this topic,&lt;br /&gt;
&lt;a href="http://www.keil.com/forum/docs/thread16271.asp"&gt;http://www.keil.com/forum/docs/thread16271.asp&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
I don&amp;#39;t like to repeat the same discussion here, join to above
thread.&lt;/p&gt;

&lt;p&gt;
Anyway, is it a homework on a university course?&lt;br /&gt;
Two different posters have the same problem at a time.&lt;br /&gt;
If so, the teacher should know that, without a hardware bus analyzer,
development of USB stack is just waste of time.&lt;/p&gt;

So 200+210 is not coming out at 411.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;what is the fault?&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Tempting to say that it comes down to the schooling.&lt;/p&gt;

... that you have hijacked this thread with a totally unrelated
question!&lt;/p&gt;

&lt;p&gt;
You need to start you own, &lt;i&gt;&lt;b&gt;new&lt;/b&gt;&lt;/i&gt; for your own
question.&lt;/p&gt;

quickly.&lt;/p&gt;

when i add to numbers i am getting the wrong answer.&lt;/p&gt;

&lt;p&gt;
example; a = 200; b = 210; c = a + b;&lt;/p&gt;

&lt;p&gt;
c is not 411.&lt;/p&gt;

&lt;p&gt;
what is the fault?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
