NAME
uscanner
- USB Scanners
SYNOPSIS
To compile this driver into the kernel,
place the following line in your
kernel configuration file:
device uscanner
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
uscanner_load="YES"
DESCRIPTION
The
driver provides support for scanners that attach to the USB port.
For each scanner attached it will provide an entry like
/dev/uscanner0
in
/dev
User-space programs, e.g. SANE,
can in turn use the device entry throgh a suitable
backend driver (see
ports/graphics/sane-backends
to control the scanner itself.
In case of multifunction USB devices (e.g. scanner/printer/card reader),
this driver only attaches to the USB interface that controls
the scanner; for the other USB interface you need separate drivers, e.g.
ulptumass
and so on.
usb
and one of
uhci
or
ohci
must be configured in the kernel as well.
HARDWARE
Because there is no standard device class for USB scanners, this driver
will only recognise devices whose USB IDs are explicitly listed in the
table in the driver itself.
