I guess you must have phy-mapphone-mdm6600 enabled as you a have working modem over USB. What do you see in dmesg if you enable n_gsm debug with modprobe n_gsm debug=0xff or on kernel cmdline? > commit 984c7706ff180e33096c57183435d925cb644576 says: > > ARM: dts: omap4-droid4: Configure uart1 pins > > These are needed to use the n_gsm driver for TS 27.010 UART > multiplexing.

We can get away without OOB wake gpio for a while as mdm6600 is not yet suspended over USB. But if you have manually suspended mdm6600 USB interface via /sys, then it won't respond properly on n_gsm either. Regards, Tony
