I'm posting this for Forrest who tried to post this but some news server
dropped it. DO NOT send me USB or driver questions. :-)

The OpenVMS USB midnight software team, the folks that brought
you the USB postal scale, USB Joystick, and other unofficial USB goodies
has a new item. The USB temperature and humidity logger.
Built around the Lascar Electronics El-USB-2 temperature and humidity
logger.

What is available is code that uses the USB generic driver to
configure and read data out of the logger. This midnight project was
completed to late to make it into the V8.3 USB demo software directory
in SYS$EXAMPLES. It should make it into the examples directory in the
future.

I can think of a number of useful things one could build using
the logger and this demo code. The hard part is done sorting out the
protocol and data formats. Now to come up with real world useful code
to take advantage of this device.

Past USB midnight products that are now part of OpenVMS
include:

USB mass storage driver
Joystick driver
USB to RS232 controllers based on
Prolific PL2303
FTDI 232
