Hi All, can any one tell me what is I am doing wrong

OS - Fedora 21 (64)
Modem - ZTE - MT 190

lsusb and usb-devices givems me below details

I have below in a file called created) /lib/udev/rules.d/61-option-modem-modeswitch.rules
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="2000", RUN+="modem-modeswitch -v 0x%s{idVendor} -p 0x%s{idProduct} -t option-zerocd"

yet it still recognised as a USB storage device, how can I get this workin

Thanks and Regards

Either just eject the device, such as "eject /dev/xxxxx", or install/run usb_modeswitch.

Hi TB0ne, thanks for the reply but nothing seems to work my network-manager simply do not recognise the modem

Thanks and Regards

Hi All, while reading I came across a post and it mentioned my devise is not supported with new kernels so what I understood and the extract of the relevant is attached

I this the case!


Kernel related issues

In some newer kernels, certain devices (some Option, some Huawei, some ZTE as mentioned above) get a special treatment in the usb-storage code to enable switching right away. You would not need USB_ModeSwitch anymore for these specific devices; on the other hand you have no choice of accessing the "CD-ROM" part of your device. Plus, there were cases when the special treatment brought no results and furthermore prevented USB_ModeSwitch to work properly afterwards (happened with ZTE devices, error "-2").
In case of trouble, look into "unusual_devs.h" in the "drivers/usb/storage" folder of your kernel source. If your default ID (vendor and product ID of the storage part) can be found there and you get errors when running USB_ModeSwitch, try first to blacklist "usb-storage".
If that helps, you should consider rebuilding your kernel with the entry in "unusual_devs.h" deactivated. The only thing that will happen is that usb-storage works in the default way afterwards.
I found a tip in the Russian Gentoo wiki to do exactly what I just suggested for the ZTE MF626.
By the way, at one point there was an agreement among USB developers to keep all future mode switching code out of the kernel drivers if the neccessary steps can be taken in "user space".

Annother way of influencing the kernel behaviour is the parameter "delay_use" of "usb-storage" which sets the time in seconds after plugging when the storage device will actually be used (and probably automounted). The default value is 5; this might affect the switching result under certain conditions.
To change the default add in /etc/modprobe.conf:

options usb-storage delay_use=1 (or 10, or other)
