I am trying to change the name "USB Serial Device (COM8)" to "DEMO NAME" under Device Manager with MCUXprC ":\MCUXpressoIDE_11.4.1_6260\workspace\evkmimxrt1020_dev_cdc_vcom_bm\sourceesso imxrt1020 sdk\usb_device_descriptor.c" file. I loaded the file from "usb_examples\dev_cdc_vcom_bm". Could anyone help me understand the file "usb_examples\dev_cdc_vcom_bm" and how to change the name of usb under device manager. Is there any source I can learn USB for deep knowledge. Thank you.
My apologies for the delay. In case it helps. A good place to start is the USB specification document, which you can find online. It is not very didactic, but it does allows you to look for how the descriptor is handled, for example.
That would be the correct place to change the string for the USB descriptor.
When working with the USB specification it’s also a good to consider USB forums as many questions are possibly answered there. There are also community threads from customers that may help.
I hope that this information helps!
