Uwatec Smart Z data download takes 1.5 hours for only 4 dives

Linus,

Indeed, the dongle is a SigmaTel STIr 4200, its ID is 066f:4200. It did 
not come with the dive computer. It was a $5.00 purchase from a webshop 
in Hongkong.

I checked the Uwatec site. The drivers they supply for Windows are named 
IR778. Amazone.com sells a "GearMo® IR778 USB Smart Infrared Device for 
UWATEC dive computer works on Windows and MAC". The distinctive lipstick 
shape could indicate they are exactly the same.

Uwatec says many IR devices will be able to communicate with Smart dive 
computers, however, they recommend their IR778. Frobese.de (makers of 
Jtrak) had a similar statement, but I'm not able to find it anymore.

I used to have another dongle, MA620. This one had a communication 
problem when used in Ubuntu downloading Smart Z data. I had to make a 
change in irlap.c and compile a new irda.ko. This had to be done after 
each kernel update.

Talking about other hardware using IR: I happen to have a Medion Pocket 
PC MD95000. I'm willing to do more data transfer speed tests (if I'm 
able to mount it) by sending forth and back a big file.
