.TH NUSBRC 8
.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"
.IR nusb (4)
.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, devies are named by ther dynamically assigned
usb device address instead. This emulates the old behaviour.

nusb: implement aijus stable uniqueue device names instead of naming devices by ther dynamically assigned device address, we hash device uniqueue fields from the device descriptor and produce a 5 digit hex string that will identify the device across machines. when there is a collision (less than 1% chance with 100 devices), usbd will append the device address to the name to make it uniqueue for this machine. the hname is passed to drivers in the devid argument, which now has the form addr:hname, where the colon and hname can be omited (for backwards compatibility). when the new behaviour isnt desired, nousbhname= environment variable can be defined giving the old behaviour. 2014-06-28 16:09:43 +00:00			`device attach and detach events by reading`
