Below I'm attaching some appropriate logs. The device id changes to 12d1:1506, but the /dev/ttyUSBn devices never appear. However, I cannot make the same thing work under Android. On a Linux computer, the USB ids for the modem is 12d1:14fe, which becomes 12d1:1506 if I enable usb_modeswitch, and it creates /dev/ttyUSB0, /dev/ttyUSB1 and /dev/ttyUSB2. The modem is Huawei E303, if the label is to be believed. I'm trying to attach a 3G USB modem to a no-name Android tablet, the version of Android is 4.0.3, the tablet is rooted.
