It would be nice to have support of UML295 3g modem. Moreover out of the box MM puts this device into almost unusable state due to endless loop of switching and it is hard to use it with e.g. wvdial. Here is the details:
- This dongle has build-in feature of switching from CD-ROM device into serial port (CDC ACM)
- When it appears in a system as serial port MM probes it (I'm not sure what it does exactly) but it causes modem to switch back to CD-ROM and so on...
- Adding ATTRS{idVendor}=="10a9", ATTRS{idProduct}=="6064", ENV{ID_MM_DEVICE_MANUAL_SCAN_ONLY}="1" to graylist resolves the problem with endless switching and it can be used by e.g. wvdial w/o problems, but still it would be nice to have it supported by MM.
- Vendor/Product IDs (serial port): 10a9:6064
- By default it introduces two devices ttyACM0, and ttyACM1, where ttyACM1 is modem port which understands AT commands (dunno what is ttyACM0). However it is possible to witch it to RNDIS mode with usb_modeswitch (PantechMode=2), then it will introduce only ttyACM0 dev which is serial port.
- See dmesg and system log for details.
If you need any additional info/logs let me know. Thanks.
