I cannot get TP-Link MA260 to work after boot. If I manually run usb_modeswitch it works, but if I unplug it and plug it back in, or after a system start or reboot, it is recognized as storage device (2357:f000) instead of modem (2357:9000). I know that MA260 exists in rules for version 2.2.6.
I'm running Linux a20-olimex, kernel 3.4.90 armv71 GNU/Linux.
Here is the dmesg output:

I even tried to add modeswitch to rc.local, but it looks that it does not run.

I'm new to Linux, so it is possible that I'm missing something obvious.

Thank you.

I suppose you tried to get a log from usb_modeswitch (see /etc/usb_modeswitch.conf)?

If you don't get any log, you might need to debug udev ...

I suggest using the command "udevadm monitor". There is documentation available about it.
