.Dt UBTHIDCTL 1
.Sh NAME
.Nm ubthidctl
.Nd "Bluetooth USB HID-HCI proxy switcher"
.Sh SYNOPSIS
.Nm
.Fl f Ar device
.Fl a Ar addr
.Op Fl m Ar mode
.Nm
.Fl t Ar tablefile
.Sh DESCRIPTION
The
.Nm
utility changes Bluetooth controllers from HID (Human Interface Device) 
to HCI (Host Controller Interface) and vice-versa.
HCI is the interface used by Bluetooth devices and HID is the interface
used by some USB devices. The device will reattach every time you switch
modes.
.Pp
Some Bluetooth controllers present themselves to the BIOS as
an
.Xr uhid 4
device.
This is done so that the user can use a Bluetooth keyboard and a Bluetooth
mouse with BIOS implementations that already support USB.
After the operating system boots, it's the system administrator's
responsibility to switch the device to HCI mode.
.Pp
This utility supports two modes of operation.
In the first one you run the utility with the exact location of the
device (device entry, address and an optional mode).
In the other mode, the utility reads a filename with several vendors
and product identifiers. If your system has a device listed in
.Pa tablefile
it will be switched to the appropriate mode automatically.
.Sh FILES
.Bl -tag -width indent
.It Pa /usr/share/misc/ubthidtbl
The location of the table file.
