Tellstick Duo connects to ttyUSB0 but drops connection

Post by gflygt » Thu Jan 18, 2018 11:08 am

I have a new install of Raspbian on an old RPI. I compiled the source code for telldus-core_2.1.2 and installed everything seems to be running fine. I get a device at /dev/ttyUSB0 BUT, after a few seconds or sometimes minutes the device is lost.

So I reconnect the tellstick. dmesg:
