The ttyS0 is connected to mdm6600, and ttyUSB4 seems to be
some buggy subset of ttyS0 n_gsm dlci1. You need need at least
the following commits in current mainline kernel:

984c7706ff18 ("ARM: dts: omap4-droid4: Configure uart1 pins")
e5b9fd7bdeb5 ("ARM: dts: omap4-droid4: Configure MDM6600 USB PHY")

And then you need PHY_MAPPHONE_MDM6600 and CONFIG_N_GSM enabled.
