1-wire sensor management

I’m using an LM5 with a DS9490R USB 1-Wire adapter connected to three wires of a DS18B20 sensor (VCC, GND, DATA). I’ve tried both with and without a pull-up resistor, and the result is the same — the sensor address is detected, but no current value is shown.

Previously, one of the three sensors worked fine with an older firmware version, but now none of them report a value, even though they’re recognized.
