Yes, mcp9600_uorb.c not support legacy implementation, but `uorb` implementation is also a character driver. The new sensor implementation also supports simple `read()`. You can look at `apps/system/sensorscope` - there are no single ioctl() call in the code. It works with `open()` and `read()` only.
