hello,
I have difficulties to use the USB interface in virtual Com mode with the microcontroller Cortex M0+ LPC11U67 manufactured by NXP.
I found a compatible driver on this link.
github.com/.../Win7_64
However, USB was installed as a USB bus controller instead of virtual com port.
I followed the steps that are on website
www.keil.com/.../rlarm_usb_create_cdc_acm.htm.
however, I have a problem with this command:
usbd_connect (__ TRUE); // Connect USB
when I do this command, my PC detects an unrecognized USB peripheral and does not display virtual com port to me.
Please how to solve this problem ?
Thank you in advance
