If the quality of the connection between the MCU and the PC is not sufficient, then the driver can't be loaded correctly by Windows.</P><P>I just tested it on my Win7 PC with a KEIL MDK4357 board in USB0 boot mode and the device gets correctly identified as "LPC device".</P><P></P><P><STRONG>Options:</STRONG></P><UL><LI>Try it with a good quality and short USB cable</LI><LI>Program a USB example from the LPC4357 SDK into the flash (for example a HID device, Windows has a driver inside) to see if the USB can then be identified by the PC</LI><LI>Work with a USB bus sniffer to see what's going on</LI><LI>Connect it to a Linux PC. I used Ubuntu 16.04, connected the board and with the command "lsusb" on the console I can see it:<BR /><SPAN style="font-family: terminal, monaco, monospace;">Bus 002 Device 006: ID 1fc9:000c NXP Semiconductors<BR /><SPAN style="font-family: arial, helvetica, sans-serif;">If you can't see it this way, then you have a USB connection quality problem</SPAN></SPAN></LI></UL><P></P><P>Regards,</P><P>Bernhard.</P></BODY></HTML> Wed, 06 Mar 2019 16:41:17 GMT https://community.nxp.com/t5/LPC-Microcontrollers/WinUSB-driver-for-LPC4357/m-p/872262#M34793 bernhardfink 2019-03-06T16:41:17Z
