usb_modeswitch suddenly stopped working with K3772-Z
Posted: 07 May 2014, 11:31
Hello all,
I've got a Raspberry Pi Model B that I'm running Arch linux on and using a Vodafone/ZTE K3772-Z USB modem for internet connection. I initially had problems getting usb_modeswitch to work on Arch (only worked when I specified a config file that I downloaded off), but I ended up doing a clean install (reflashing the SD card) and the installing the usb_modeswitch package via pacman and since then it's worked fine, with the device automatically switching once plugged in.
However, after leaving the Pi running for a few days, I've since come back to it and found that the dongle will not automatically switch when plugged in. I've enabled logging in usb_modeswitch, and here's the output of the log when I plug my device in:
Here's also the output of the system log (via journalctl) when I plug the device in:
The output of usb_modeswitch -W is shown below:
Although Arch linux on the Raspberry Pi doesn't have a separate usb_modeswitch_data package, I'm fairly certain it's already there since /usr/share/usb_modeswitch is populated with files for every combination of VID/PID.
I initially thought the modem might be at fault, but plugging into a Windows machine shows that it still seems to work fine.
I tried to run usb_modeswitch manually using a config file I'd found online that worked before (from http://www.linuxquestions.org/questions ... ost4756940) using usb_modeswitch -c dongle.txt, but that didn't work either. Here's the output:
Any thoughts?
Thanks
Amr
