Hi! I got an error at the last step.
I am using Micromax MMX 355g 3G modem HSPA 7.2mbps.
Configuration will be very difficult and detection of driver also difficult.
I just did the above steps are fine upto
modprobe statement and at last statement:
usb_modeswitch -c /etc/usb_modeswitch.d/1dbc:0669.
I got the error is no driver found, but usb storage driver is found and product id is also found:
Looking for target devices ... found matching product ID adding device Found devices in target mode or class (1) Looking for default devices ... found matching product ID adding device Found device in default mode, class or configuration (1) Accessing device 006 on bus 001 ...
