Is there any way some sort of a more unique identifier could be made for these so that I can keep using /dev/serial/by-id/ rather than semi-random /dev/ttyUSB* numbers? Especially because these two devices are really different, one is model E180 and the other is model E160, they have different SIM cards/ISPs so they must have different IMEIs, etc.
If there is no way in the serial driver, there still may be a chance using the storage portion of the devices. They are automatically switched by the kernel with "usb_stor_huawei_e220_init", started by an entry in "unusual_devs.h".
To access the storage part (containing the Windows driver) you'd have to out-comment the entry for your ID in "unusual_devs.h".
Then check and compare the SCSI identifiers after plugging in. If there are no differences either, there is still the content of the storage to test; it should be provider-specific.
Once you have found a significant difference, you can switch the devices to modem mode with the help of a userspace program, and create a script or something to do all that automagically via udev.
