NAME
     upd -- USB	Power Devices sensor

SYNOPSIS
     upd* at uhidev?

DESCRIPTION
     The upd driver provides support for monitoring various sensors provided
     by	USB Power Devices (such	as a UPS).  Supported sensor values are	made
     available via the sysctl(8) interface.

     The following sensors are supported by the	driver:

	   BatteryPresent
	   ShutdownImminent
	   ACPresent
	   Overload
	   RelativeStateOfCharge
	   AbsoluteStateOfCharge
	   RemainingCapacity
	   FullChargeCapacity
	   Charging
	   Discharging
	   AtRateTimeToFull
	   AtRateTimeToEmpty
	   RunTimeToEmpty
	   NeedReplacement

     The USB Power Devices specification can be	found at:

HISTORY
     The upd driver first appeared in OpenBSD 5.6.

AUTHORS
     The upd driver was	written	by Andre de Oliveira.

BUGS
     The upd driver does not indicate device health via	aggregate or individ-
     ual sensor	status.	 Users who wish	to monitor upd status using
     sensorsd(8) must manually establish "high"	and "low" limits for sensor
     values of interest	via sensorsd.conf(5).
