Hi All,

i've been trying to use a Huawei 3G net stick with a device running embedded linux (2.6.31).
it seems that most of the "howto" out there is for systems using udev.
i've tried using usb modeswitch, but it's not working properly with mdev. after looking online, i found a script that creates the path "/dev/bus/usb" and the files in it required for running usb_modeswitch.
now that i have this script, and added usb_modeswitch, libusb & libusb-compat, i need to add them to the hotplug script so that they will be called when I plug in the net stick. (automation)

It seems that the part calling the hotplag when connecting the net stick, is not installed/working.
does anyone have an idea on how to enable proper mounting of the net stick (as CD ROM) and get the hot-plug to react to it?

here is a trace of the usb enumeration:

thank you in advance,

Hello and welcome to LQ.

Seems the stupid deal has some mass storage in it. I had a CF wifi that was like that too. Not a deal breaker but a pesky issue.

See this for some ideas. https://wiki.archlinux.org/index.php...E1550_3G_modem

thank you for the help!
I've actually figured it out, the MOD_SR flag was not enabled.
once I've enabled it, and loaded the mod_sr.ko, the hotplug recognized that a "cd-rom" was plugged in.

Thanks for the update and solution.
