After a few hours research at the internet, I found this page:

with this short Howto:

- install the irda-utils package for your distribution
- Upon inserting the device, this adapter will automatically be 
recognized as ID 9710:7780 MosChip Semiconductor MCS7780 4Mbps Fast IrDA 
Adapter and the mcs7780.ko driver loaded
- The user will likely have to manually load the IRCOMM driver as root 
user, e.g. "modprobe ircomm-tty" *, which will automatically load 
ircomm.ko as well. -- al: this automagicly loaded for me.
- Now, the irda0 pseudo device will be available, e.g. "iwconfig" will 
list irda0, but "ifconfig" won't as the irda0 interface hasn't been 
- So as root, execute "ifconfig irda0 up" which initializes the irda0 
interface [THIS is the magic command that makes it all work that seems 
to be missing from a few guides --Alex.]
- Next as root, execute "irattach irda0 -s" (discovery)
- Next as root, execute "irdadump" in a terminal
- start the subsurface programm and "Import > from Dive Computer > 
Manufactor Uwatec with Model Galileo Luna"

Now I have all my dives from the dive computer on my Laptop.
