I bought a brand new Macbook Pro last week, and have also bought a 3g USB modem to go with it. Plugged it in and nothing happened, didn't mount or show up in finder at all. Plugged it into my old Macbook (mid 2008, running lion) and it worked perfectly, software installed etc. I then moved back to my new Macbook Pro and plugged the modem into the Apple USB keyboard which was plugged into my Macbook Pro and it worked, software installed, connected to the internet, but it wont work if its plugged straight into the MacBook Pro. So essentially the modem works straight into a USB port on an old macbook, but doesn't on a new macbook pro, but does work when plugged through another USB device (I have only tested on a apple keyboard as I dont have a USB hub on me) Anybody got any ideas? I would love to get it working normally so i can take it travelling, no point taking a keyboard with me!
