topic Can PC communicate with USB HID with INT EndPoint? in LPC Microcontrollers https://community.nxp.com/t5/LPC-Microcontrollers/Can-PC-communicate-with-USB-HID-with-INT-EndPoint/m-p/523190#M5826 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by iamonline on Sat Aug 09 22:23:58 MST 2014</STRONG><BR /><SPAN>Hi:</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp; There are 4-cdc &amp; 1-hid device(composite device) on my LPC1768 Platform. When power on, usb enum is OK. I can also write data to the CDC Endpoint by calling USB_WriteEP() function and PC can receive the data. But when I write data to the HID IN EndPoint, PC can not read these data. Can any body give me some advice why I cannot write data to HID EP directly? Can only the HID exchange data with PC by HID report? </SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp; Thanks a lot.</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 16:44:26 GMT lpcware 2016-06-15T16:44:26Z Can PC communicate with USB HID with INT EndPoint? https://community.nxp.com/t5/LPC-Microcontrollers/Can-PC-communicate-with-USB-HID-with-INT-EndPoint/m-p/523190#M5826 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by iamonline on Sat Aug 09 22:23:58 MST 2014</STRONG><BR /><SPAN>Hi:</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp; There are 4-cdc &amp; 1-hid device(composite device) on my LPC1768 Platform.
