Yawn, yup boring unless a sponsor of your deployment is a 3G service
provider, then it becomes a major 'has to work out of the box' from  a
business point of view. If it's as simple as adding a single entry to
powerd's usb-inhibits file like how 'hid' is treated then why has this not
been done? I don't think having an end-user with no experience with USB IDs
add an entry to the usb-inhibits file, or having to remember to turn off a
major feature is the correct long term solution IMHO.

just my thoughts,
