I got the XMM 7360 running on my EB 840 G5 but it took a lot of firmware updates and drivers and holding my mouth right. I'm having a heck of a time with a pair of EB 745 G5's, I'd sure like to send them out to my users but I can't get the dang modems working.
This is not happy making! I never did hear back from HP's EliteBook support after opening a case about my 840, I left for a tech conference after I got that device working so I didn't follow up. Of course, neither did they, so maybe they didn't expect a resolution?
Edit to add; The number for EliteBook support 24/7 is 866.625.1175 and my case number was 5037328215. I've previously had excellent results contacting EliteBook support, so this was disappointing. This forum is clearly not an improvement!
