[SOLVED] HP lt4112 Gobi 4G Module (03f0:581d) not working

halogene · 2015-06-24 08:41:03

As far as I've read, kernel support should have been added to this modem by now. I have followed the instructions on the wiki and did quite some internet research, but to no avail.

I got it to work ONCE though, if I remember correctly it was after doing

echo "03f0 581d" > /sys/bus/usb-serial/drivers/qcserial/new_id

and then reloading the module qcserial and restarting ModemManager. But that doesn't seem to work anymore.

Relevant outputs (I'll post more if required):

It seems that "new_id" file is at the wrong place. I checked my bash history (thank god it's there!), and found out that back then, when it worked, I had put the "new_id" file into

/sys/bus/usb-serial/drivers/generic/

Now the modem registers after doing

sudo rmmod qcserial
sudo modprobe qcserial vendor=0x03f0 product=0x581d
sudo systemctl restart ModemManager 
sudo systemctl restart NetworkManager

However, the device immediately disconnects with a timeout error.

systemctl status ModemManager gives:

Seems that the remaining problem has something to do with my SIM card. Works on another one. (Turns out it was not activated, duh!)

Of course I now have to perform the steps over and over again (unloading module, modifying the new_id file, loading module, restarting ModemManager). Is there a way to fix this for good (without doing all those steps with a script I mean)?

If your modem is covered by usb_modeswitch, it would switch it to correct mode automatically, but It seems that new systemd/udev broke usb_modeswitch.
