Hi Jean-Pierre,
I've the same problem as you. I received this week a "Vodafone Mobile Connect HSDPA/UTMS/EDGE datacard" from Vodafone (Germany).
I installed the last version of VMC (2.03.1 : from
http://www.vodafone.de/hilfe_kundenservice/download/63052.html), but when I launch VMC : it also replies "No modem found" and the application quits. The model and the manufacturer is "Unknown"...
Because my OSX.4.5 is in French and I use a German network, I also tried to install VMC with my OS in German and with my OS in English. The result is the same : the card still be unknown.
The blue and pink leds blink together too. But for the blinking, I think that it's normal (written in the documentation of card).
The Vodafone Mobile Connect HSDPA/UTMS/EDGE datacard is a new card. I think that we've to wait for a new update of VMC. On this page (
http://www.vodafone.de/hilfe_kundenservice/download/63052.html), VMC seams to be only compatible with the "Vodafone Mobile Connect Card UMTS" and the "Vodafone Mobile Connect Card UMTS Novatel U630".
Monday, I'll go to Vodofone shop in order to obtain an "old" UTMS card which works under OSX.
