My original posting was:

I recieved three responses, one saying it works fine, and two doubting
that it would work:

The positive response was:

I asked a follow up question and recieved further info:

The two doubtfull responses were:

This is not true ... the ALM-1 works under 4.1.1 and there is a device driver
provided.
