Sierra Wireless MC8781

You are right:

Those two have receive equalizer with dual antenna diversity.

- MC8780: 850/2100 MHZ optimized for Europe and Asia Pacific

- MC8781: 850/1900 MHZ optimized for North America

And this card supports tri-band UMTS/HSPA so in MC8781 case I think it prioritize UMTS/HSPA usage - cause between GPRS and UMTS it expects EDGE and cause of US optimization in europe it doesn't detect any so it pushes it to higher frequency. That is why I have observed higher speeds on this modem or this is another placebo effect

I'll soon get my hands on MC8775 so I'll have a comparison.

My friend just bought Sierra Wireless MC8775 for his WinXP thinkpad. I had 30 minutes to check it against my E6400 Lion and I'm happy to report that it works! I had issues connecting by AirCard Watcher that I use for MC8781 but I guess this can be easily fixed by using other one (for 875U).

Well, the one thing I know: it is NOT in USB mode. There is no USB storage or partition to be seen. At least in Finder, PathFinder and Disk Utility.

 

@Mariusz

Is this out of your System Information or have you used any kind of a tool to extract this info?

Yes its System Information > Hardware > USB
