Cannot able to detect ttyUSB interface with option GSM driver #136

What steps will reproduce the problem?
1. Build Gingerbread kernel (2.6.37) image with options:
   CONFIG_USB_SERIAL_WWAN=y
   CONFIG_USB_SERIAL_OPTION=y

2. Loaded kernel image on beagleboard, detected option drivers

3. dmesg | grep option
   "USB Serial support registered for GSM modem (1-port)                            
usbcore: registered new interface driver option                                 
option: v0.7.2.1:USB Driver for GSM modems"

4. plugged-in the novatel device on beagleboard

5. but no ttyUSB* found in "ls /dev/ttyUSB* "

I tried the same thing on ubuntu by building for kernel-2.6.37 and ttyUSB* were 
successfully detected

You probably need to edit ueventd.rc

This TI e2e post could give you some pointers..

I added "/dev/ttyUSB0              0660   radio      radio" in ueventd.rc but 
still the interface is not detected
