--Sig_/yU=6rfK1L/9sco8CZOexKVw Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable For temperature monitoring, we have a bunch of Digi Watchport/T sensors:=20 http://ftp1.digi.com/support/documentation/90000406_H.pdf They work well with CentOS 5/6 systems and there is also a Nagios plugin, w= ritten in Perl, which makes those sensors usable with Nagios/Icinga/Icinga2:=20 =20 https://exchange.nagios.org/directory/Plugins/System-Metrics/Environmental/= check_watchptTemp/details When attached to FreeBSD 12-CURRENT, the sensor is seen as a generic USB de= vice, for instance ugen2.7: <WatchportT Digi International> at usbus2, cfg=3D0 md=3DHOST spd= =3DFULL (12Mbps) pwr=3DON (80mA) I tried to load any available USB serial port/adaptor driver available to m= ake this sensor attach as a ttyU? as it does in Linux (/dev/ttyUSB), but no luck so = far. I'm not familiar with serial consoles or the derial capabilities of FreeBSD, so i m= ight have overseen something essential. I'd like to access the sensor to retrieve tem= perature data, even if it is in a crude way. Poking around with USB, I found that the sens= or device does release some informations, so hopefully there is a way to make it look like= a tty, see my attempts to get some informations out of the device below. If someone has some help, hints or advice, I'd appreciate an email (please = CC me, I do not subscribe the QUESTION list).
