.SH NAME
nusbrc - Universal Serial Bus startup script
.SH SYNOPSIS
.B nusbrc
.SH DESCRIPTION
Started by
.I bootrc
(see
.IR boot (8)),
.I termrc
or
.I cpurc
(see
.IR cpurc (8)),
.I nusbrc
handles the startup and shutdown of usb drivers on physical
device attach and detach events by reading
.B /dev/usbevent
file.
.SH SOURCE
.B /rc/bin/nusbrc
.B /sys/src/9/boot/nusbrc
.SH "SEE ALSO"

.SH BUGS
Usb devices appear as files under
.B /dev
and
.B /shr
identified by the devices unique name assigned by usbd.
When the environment variable
.I nousbhname
is defined, devices are named by their dynamically assigned
usb device address instead. This emulates the old behaviour.
