- Install the Connection Manager that is launched when you connect the modem to the Mac
- Download the source of
usb_modeswitch
from here http://www.draisberghof.de/usb_modeswitch/ (at the moment of writing this the file appears with the name usb-modeswitch-2.5.2.tar.bz2) - Run
make
in the directory of the source you downloaded - Run
sudo ./usb_modeswitch -v12d1 -p1505 -X
in the same directory
If the last step returns an error (I don't remember the error now, but I was getting an error related to usb_modeswitch
not being able to take control of the modem to perfom changes):
- Unplug the modem and plug it again
- As soon as you plug the modem again, run
sudo ./usb_modeswitch -v12d1 -p1505 -X
repatedly until you get a successful result - Open Connection Manager and your modem is going to be detected
@LarkinZero that error is telling you that some other program is using the device. Maybe you have some driver or similar that is taking control of your USB device? If that's the case, you have to uninstall that driver or unload it, and then run
usb_modeswitch
