I think if the hardware has the EPs, they should be exposed by the
driver. You can tweak usermode as to whether they get device nodes,
what they're called, etc.

Phil Karn mentions on http://www.ka9q.net/5220.html:
It may help to know what's actually inside the 5220 card. It
contains a Qualcomm MSM 5500 mobile station modem chip that
implements the actual 1xEV-DO functionality. This chip has a native
USB 1.1 interface that emulates two USB serial ports. The first
provides a classic serial modem interface that accepts AT commands
and PPP data. The second is reserved for diagnostics and is unused.
