"On the Neo900, the modem is connected via USB (bus; there is no physical connector) which means it doesn't have DMA." I have been "Mr. Cry About Baseband Ownage From The Rooftops" for years around here, and even I have to admit that a lot of baseband implementation in modern smartphones uses this same USB connected model. It's not universal, but a lot of USB-connected baseband is out in the world... Still closed source and owned by the provider. I would love to see an open source baseband with a hard switch to disable it.
