.Sh NAME
.Nm usb_quirk
.Nd USB quirks module
.Sh SYNOPSIS
To compile this module into the kernel,
place the following line in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device usb"
.Ed
.Pp
Alternatively, to load the module at boot
time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent

See
.Pa /sys/dev/usb/quirk/usb_quirk.h
or run "usbconfig dump_quirk_names" for the complete list of supported quirks.
.Sh LOADER TUNABLE
The following tunable can be set at the
.Xr loader 8
prompt before booting the kernel, or stored in
.Xr loader.conf 5 .
.Bl -tag -width indent
.It Va hw.usb.quirk.%d
The value is a string whose format is:
.Bd -literal -offset indent
.Qo VendorId ProductId LowRevision HighRevision UQ_QUIRK,... Qc
.Ed
.Pp
Installs the quirks
.Ic UQ_QUIRK,...
for all USB devices matching
.Ic VendorId
and
.Ic ProductId
which have a hardware revision between and including
.Ic LowRevision
and
.Ic HighRevision .
.Pp
.Ic VendorId ,
.Ic ProductId ,
.Ic LowRevision
and
.Ic HighRevision
are all 16 bits numbers which can be decimal or hexadecimal based.
.Pp
A maximum of 100 variables
.Ic hw.usb.quirk.0, .1, ..., .99
can be defined.
.Pp
If a matching entry is found in the kernel's internal quirks table, it
is replaced by the new definition.
.Pp
Else a new entry is created given that the quirk table is not full.
.Pp
The kernel iterates over the
.Ic hw.usb.quirk.N
variables starting at
.Ic N = 0
and stops at
.Ic N = 99
or the first non-existing one.
.El
.Sh EXAMPLES
After attaching a
.Nm u3g
device which appears as a USB device on
.Pa ugen0.3 :
.Bd -literal -offset indent
usbconfig -d ugen0.3 add_quirk UQ_MSC_EJECT_WAIT
.Ed
.Pp
Enable a Holtec/Keep Out F85 gaming keyboard on
.Pa ugen1.4 :
.Bd -literal -offset indent
usbconfig -d ugen1.4 add_quirk UQ_KBD_BOOTPROTO
.Ed
.Pp
To install a quirk at boot time, place one or several lines like the
following in
.Xr loader.conf 5 :
.Bd -literal -offset indent
hw.usb.quirk.0="0x04d9 0xfa50 0 0xffff UQ_KBD_IGNORE"
