In file "chip_18xx_43xx.c" there is a function "Chip_USB1_Init(void)". In this function the Register "SFSUSB" is set to "0x12" but it must be "0x32" for enable USB1.</P> Fri, 16 Apr 2021 10:12:39 GMT wut 2021-04-16T10:12:39Z https://community.nxp.com/t5/LPC-Microcontrollers/How-to-get-USB1-working-LPCXpresso43xx/m-p/1263411#M44682 <P>Hello,</P><P>I use the LPCXpresso43xx Board an want to get USB1 working. For this I use the software example "usbd_rom_msc_ram" and changed the entry "#define USE_USB0" to&nbsp; "#define USE_USB1" in file "app_usbd_cfg.h".</P><P>Mabey I should mention that I first try the example for USB0 and everything works perfect. For testing USB1 I connect USB1_DP (green), USB1_DM (white), GND and VCC_from_usb -&gt; 5V. But this is not working. Does anybody have any idea why it is not working?</P><P>Thank you for your help!</P> Fri, 16 Apr 2021 09:05:49 GMT https://community.nxp.com/t5/LPC-Microcontrollers/How-to-get-USB1-working-LPCXpresso43xx/m-p/1263411#M44682 wut 2021-04-16T09:05:49Z https://community.nxp.com/t5/LPC-Microcontrollers/How-to-get-USB1-working-LPCXpresso43xx/m-p/1263480#M44687 <P>I found the solution by myself!
