So you've already done a lot of debugging -- the fuse system works, and the hardware works on another system.

Thus the problem is with serial port handling (hardware or kernel or maybe timing).

digitemp http://www.digitemp.com/ has support for the DS9097E passive adapter and would be another test of the hardware.

It shouldn't be a polarity issue, but it could be a voltage problem on the embedded board. The passive adapter steals power from the serial pins.

You mean it steals power for the adapter, or the sensor own? (I think for the sensor, cause the adapter has only passive parts) The sensor works in parasite mode. May the problem resolved by directly powering the sensor?
