USFS(4) FreeBSD Kernel Interfaces Manual USFS(4)
NAME
usfs - USB device side support for bulk only transport mass storage
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
device usb
device usfs
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
usfs_load="YES"
DESCRIPTION
This driver is obsolete. Users are advised to use cfumass(4) instead.
The usfs driver provides support for emulating an USB mass storage device
when the USB stack is activated in USB device side mode (the
usb_template(4) module is loaded and the hw.usb.template sysctl is set to
0).
Upon attach the driver creates a RAM disk which can be read and written.
