Hi

We are using Quark_C1000 controller in our project along with zephyr 1.6.
I could see zephyr 1.6 has support for USB.

I have a query.

We are currently having a requirement of send some commands via USB (from
a PC)  and based on the commands received (in the device ) we will execute
certain applications.

For this requirement I need clarifications regarding the USB driver.

I could see that the USB DFU handles command which is sent from a PC.

Do I need to expand this driver itself for my requirement or Should I use
the USB UART driver for my requirement ?

It is easier to use cdc_acm sample in samples/usb/cdc_acm, then your PC
already has the driver for it and it appears on your PC as ttyACM or
ttyUSB, then you can communicate over serial.

If you want to implement certain USB class like Bluetooth in hci_usb
sample you should look here: samples/bluetooth/hci_usb/

For other samples you need AFAIK to have certain driver, like btusb for
hci_usb, etc.
