[-- Attachment #1 --] For temperature monitoring, we have a bunch of Digi Watchport/T sensors: http://ftp1.digi.com/support/documentation/90000406_H.pdf They work well with CentOS 5/6 systems and there is also a Nagios plugin, written in Perl, which makes those sensors usable with Nagios/Icinga/Icinga2: 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 device, for instance ugen2.7: <WatchportT Digi International> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (80mA) I tried to load any available USB serial port/adaptor driver available to make 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 might have overseen something essential. I'd like to access the sensor to retrieve temperature data, even if it is in a crude way. Poking around with USB, I found that the sensor 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). Thanks in advance, Oliver # usbconfig -u 2 -a 7 dump_device_desc ugen2.7: <WatchportT Digi International> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (80mA) bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0110 bDeviceClass = 0x00ff <Vendor specific> bDeviceSubClass = 0x0000 bDeviceProtocol = 0x00ff bMaxPacketSize0 = 0x0008 idVendor = 0x1608 idProduct = 0x0304 bcdDevice = 0x0100 iManufacturer = 0x0001 <Digi International> iProduct = 0x0002 <Watchport/T> iSerialNumber = 0x0003 <W82765150-0> bNumConfigurations = 0x0001 # usbconfig -u 2 -a 7 dump_all_config_desc ugen2.7: <WatchportT Digi International> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (80mA) Configuration index 0 bLength = 0x0009 bDescriptorType = 0x0002 wTotalLength = 0x0027 bNumInterfaces = 0x0001 bConfigurationValue = 0x0001 iConfiguration = 0x0000 <no string> bmAttributes = 0x00a0 bMaxPower = 0x0028 Interface 0 bLength = 0x0009 bDescriptorType = 0x0004 bInterfaceNumber = 0x0000 bAlternateSetting = 0x0000 bNumEndpoints = 0x0003 bInterfaceClass = 0x00ff <Vendor specific> bInterfaceSubClass = 0x0000 bInterfaceProtocol = 0x00ff iInterface = 0x0000 <no string> Endpoint 0 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0081 <IN> bmAttributes = 0x0002 <BULK> wMaxPacketSize = 0x0040 bInterval = 0x0000 bRefresh = 0x0000 bSynchAddress = 0x0000 Endpoint 1 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0001 <OUT> bmAttributes = 0x0002 <BULK> wMaxPacketSize = 0x0040 bInterval = 0x0000 bRefresh = 0x0000 bSynchAddress = 0x0000 Endpoint 2 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0087 <IN> bmAttributes = 0x0003 <INTERRUPT> wMaxPacketSize = 0x0008 bInterval = 0x0001 bRefresh = 0x0000 bSynchAddress = 0x0000 [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJXkktsAAoJEOgBcD7A/5N8z34H/j3Zg8eBnzTHXMRX4sTeqQYd gojIaaCkejI5svgzT5UcpDBe7OVizZWNWtJCC+KkMoDKlKlfqMO85Qgd9rSVKw6c NGksLFPH5JHtxXQjYzEQBP4AI5ZifT99WIumyARHLS3okohi8mafyuzRIstetgTp c861/u6LjMGDXWgMl+c8E3Ds7khi2RQbl3wetPKhfAvziGlTZBIxEjre8rlgHD81 6y2mbTrkWVRpl4A1lHdHFhvb/zvXP8gJva2G/z8ao08rUFqJj1cL4t50/5ZQSaGY LUqi4LCRClVUDlM0Ex3BmhgGjeRvTg8tjQqbWZGeSxZykpqHG8DhLP8on2U9BkM= =D3zW -----END PGP SIGNATURE-----
