I found some directions that might help.

Enabling USB-C OTG Device Mode :
Ensure the Linux device has a USB-C port that supports OTG functionality.
In the device tree, set the dr_mode property of the USB OTG controller to "peripheral" or "otg" to enable device mode.
Configure the TUSB320 USB-C controller (or equivalent) to operate in UFP (Upstream Facing Port) mode, which allows the device to act as a USB peripheral.
Configuring USB Gadget Drivers :
Load the appropriate Linux USB gadget driver for the desired functionality, such as g_ether for Ethernet over USB, g_serial for a serial device, etc.
Manually configure the USB network interface, such as assigning an IP address to usb0.
Connecting to a Host :
Use a USB-C to USB-C or USB-C to USB-A cable to connect the Linux device in OTG device mode to a host PC.
The host PC should then detect the Linux device as a USB peripheral, allowing file transfer, network connectivity, or other functionality depending on the configured gadget driver.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
