I opened one of those digi watchports since I read that Ti has discontinued the TI5052 chip and encourage developers to use a newer one. The print on the chip itself residing on the PCB is TUSB3410I and this refers to a Ti TUSB3410 as it is referred to by the TI 5052 page: http://www.ti.com/product/TUSB3410 I never wrote a driver my own, so starting from scratch would be inefficient, but for the long shot, it might be an idea. Thanks anyway for the efford taken to look into it. I hope we will see at least some manpage for ugensa. I'm still looking for simple sensor devices which could be attached to FreeBSD for monitoring temperature and/or humidity - as it was intended by using the digi watchport. I'm now with an experimental piece of hardware with two DALLAS DS18B20 temperature sensors. It is a USB interface PCB with an AT90USB162 microcontroler chip. Attached to a FreeBSD 12-CURRENT system, it reports itself as a UHID device. there is also a software package available - for Windows and Linux, but it doesn't work for FreeBSD, the package compiles and produces a cmdline binary, but it fails reading the sensor data - the uhid driver seems to be unloaded during the call. I have no skills in writing low-level USB software, so my explanation is slopy, sorry. But there is hope I can use this one.
