By USB interface, do you mean data transfer or interfacing another device over USB?
Please elaborate your query.
Thanks for reply.
I need to transfer the HCI commands over the USB interface from linux mahine. Is CYW920719 provides USB interface?. If it supports can I send HCI commands to the board using python pyusb module?
20719 Supports HCI UART interface to send / receive HCI command . If you want a USB connection , then may need to connect USB to UART converter in between .
