* The outgoing commands are sent with HID Set_Report commands over EP0
* (control message), and incoming commands are received on EP1IN (interrupt
* endpoint). The UPS completely ignores the conventions of Set_Idle (where
* you NAK the interrupt read if you have no new data), so you constantly have
* to poll EP1IN.
*
* The descriptors say that bInterval is 10 ms. You generally need to wait at
* least 80-90 ms to get some characters back from the device. If it takes
* more than 250 ms, you probably need to resend the command.
*
* All outgoing commands are followed by a checksum, which is 255 - (sum of
* characters after ':'), and then by '\r'. All responses should start with
* the command letter that was sent (no colon), and should be followed by
* '\r'. If the command is not supported (or apparently if there is a serial
* timeout internally), the previous response will be echoed back.

=head1 NAME
tripplite_usb - Driver for older Tripp Lite USB UPSes (not PDC HID)
=head1 NOTE
This man page only documents the hardware-specific features of the
tripplite_usb driver. For information about the core driver, see
nutupsdrv(8).
=head1 SUPPORTED HARDWARE
This driver should work with older Tripp Lite UPSes which are detected as USB
HID-class devices, but are not true HID Power-Device Class devices. So far,
the devices supported by tripplite_usb have product ID 0001, and the newer
units (such as those with "LCD" in the model name) with product ID 2001 require
the usbhid-ups driver instead. Please report success or failure to
the nut-upsuser mailing list. A key piece of information is the protocol
number, returned in ups.debug.0. Also, be sure to turn on debugging (C<-DDD>)
for more informative log messages. If your Tripp Lite UPS uses a serial port,
you may wish to investigate the tripplite(8) or tripplite_su(8) driver.
This driver has been tested with the following models:
=over
=item * INTERNETOFFICE700
=item * OMNISV1000
=item * OMNISV1500XL (some warnings)
=item * SMART700USB
=item * SMART1500RM2U
=item * SMART2200RMXL2U
=item * SMART3000RM2U
=back
If you have used Tripp Lite's PowerAlert software to connect to your UPS, there
is a good chance that tripplite_usb(8) will work if it uses one of the
following protocols:
=over
=item * Protocol 0004
=item * Protocol 1001
=item * Protocol 2001
=item * Protocol 3003
=back
=head1 EXTRA ARGUMENTS
This driver supports the following optional setting in the ups.conf(5) file
(or with C<-x> on the command line):
=over
=item offdelay
This setting controls the delay between receiving the "kill" command (C<-k>)
and actually cutting power to the computer.
=item bus
This regular expression is used to match the USB bus (as seen in
C</proc/bus/usb/devices> or lsusb(8); including leading zeroes).
=item product
A regular expression to match the product string for the UPS. This would be
useful if you have two different Tripp Lite UPS models connected to the
system, and you want to be sure that you shut them down in the correct order.
Note that this regex is matched against the full USB product string as seen in
lsusb(8). The C<ups.model> in the C<upsc> output only lists the name after
"TRIPP LITE", so to match a SMART2200RMXL2U, you could use the regex
".*SMART2200.*".
=item productid
The productid is a regular expression which matches the UPS PID as four
hexadecimal digits. So far, the only devices that work with this driver have
PID C<0001>.
=item serial
It does not appear that these particular Tripp Lite UPSes use the iSerial
descriptor field to return a serial number. However, in case your unit does,
you may specify it here.
=back
For more information on regular expressions, see regex(7)
=head1 RUNTIME VARIABLES
=over
=item ups.delay.shutdown
This variable is the same as the C<offdelay> setting, but it can be changed at
runtime by upsrw(8).
=item ups.id
Some SMARTPRO models feature an ID that can be set and retrieved. If your UPS
supports this feature, this variable will be listed in the output of upsrw(8).
=item outlet.1.switch
Some Tripp Lite units have a switchable outlet (usually outlet #1) which can be
turned on and off by writing C<1> or C<0>, respectively, to C<outlet.1.switch>.
If your unit has multiple switchable outlets, substitute the outlet number for
"1" in the variable name. Be sure to test this first - there is no other way to
be certain that the number used by the driver matches the label on the unit.
=back
=head1 KNOWN ISSUES AND BUGS
The driver was not developed with any official documentation from Tripp Lite,
so certain events may confuse the driver. If you observe any strange behavior,
please re-run the driver with C<-DDD> to increase the verbosity.
So far, the Tripp Lite UPSes do not seem to have any serial number or other
unique identifier accessible through USB. Thus, when monitoring several Tripp
Lite USB UPSes, you should use either the C<bus> or C<product> configuration
options to uniquely specify which UPS a given driver instance should control.
For instance, you can easily monitor an OMNIVS1000 and a SMART1500RM2U at the
same time, since they have different USB Product ID strings. If you have two
SMART1500RM2U units, you would have to find which USB bus number each unit is
on (via C<lsusb>), which may result in ambiguities if the available USB ports
are on the same bus.
Some of the SMART*2U models have an ID number, but because this ID is not
exposed as a USB string descriptor, there is no easy way to use this ID to
distinguish between multiple UPS units on a single machine.
