After two years of null-activity in the area of Huawei devices I'm resuming the work. Right now I'm in a process of coding
a python package, PyHumod, that will talk to Huawei (and compatible) modems. I've just jotted a detection tool for Huawei interfaces on a HAL-enabled Linux.
Run it as follows:
$ python find_huawei_iface.py
It should come up with something like that as response:
5 Huawei interfaces detected.
E220 HSDPA Modem : /dev/ttyUSB4
E220 HSDPA Modem : /dev/ttyUSB3
E620 USB Modem : /dev/ttyUSB1
E620 USB Modem : /dev/ttyUSB2
E620 USB Modem : /dev/ttyUSB0
Tested on Huawei E220, K3520 and E270. It's meant to work with all models.
