Hi 

 
My device is self-powered, usb connection is optional, so user may
connect/disconnect it many times in the run time. 

 
Previously I use MDK421, EP1 in is used, pc software use interrupt
transfer to read EP1 data, usbd_hid_get_report() gets</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: How to ask windows driver polling the EP1 data every 32 ms in MDK423</title><link>https://community.arm.com/thread/60242?ContentTypeID=1</link><pubDate>Mon, 09 Apr 2012 12:05:57 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ab4b7d7f-602f-4dec-acea-25a63d41d709</guid><dc:creator>Thomas Ruschival</dc:creator><description>&lt;p&gt;&lt;p&gt;
Confirmed with NXP LPC1769 (running example
Boards/keil/MCB1700/RL/USB/RTX/Device/HID)&lt;br /&gt;
I am using the KEIL HID Client program that modifies LEDs and reads
buttons.&lt;/p&gt;

&lt;p&gt;
I set a breakpoint on the first switch(rtype) which never gets
hit....&lt;br /&gt;
According to the callgraph it should get called by
USBD_HID_GetReport&lt;br /&gt;
and USBD_HID_EP_INTIN_Event but it isn&amp;#39;t - I can&amp;#39;t cause any event
that would call the function...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
