I’m using openSUSE 11.3 and i access internet through usb-stick.
Before inserting my usb-stick, i generally remove the usb-storage module driver by this command:
modprobe -r usb-storage
But after this command, i get an output saying that usb-storage is built in and cannot be removed.
Can anybody help me how to remove that module. It works well under ubuntu and Mandriva.
Thanks in advance.

Why do you need to remove usb-storage? I have a number of wireless USB devices,
and none of them have any problems with USB-storage.
Most drivers can be built either as a module or built into the kernel. As the
message states, the standard openSUSE kernel has it built in. As a result, it
cannot be removed. To remove it, you will need to get the kernel source, modify
the configuration to change usb-storage into a module, build a new kernel, and
boot that kernel. As that involves a fair amount of work, we should first be
certain you need to do it.
I need to remove usb-storage because my usb-stick is getting detected as a storage device.
usb_modeswitch package doesn’t seem to switch my usb-stick to a modem device. If i use the usb_modeswitch package, it temporarily switches it to a ttyUSB0 device but soon it gets disconnected, And this switching continues like a endless loop.
In other distribution like ubuntu or mandriva, i don’t even install usb_modeswitch package. I just remove the usb-storage driver and register my usb-stick with this command:
modprobe usbserial vendor=0x201e product=0x1008
And this makes my usb-stick get detected as a modem. But since in openSUSE even if i register my usb-stick device with usbserial driver, i’m not able to get it detected as a modem because i’m not able to remove the usb-storage driver.
It might be worth contacting the usb_modeswitch developers if you need support with your hardware:
Draisberghof - Software - USB_ModeSwitch
Instead of disabling the usb-storage driver, try ‘eject /dev/sr1’ (or similar). You can use ‘dmesg |tail’ to find the applicable device node. I remember that I used to have a huawei device (back with openSUSE 10.2/11), which behaved the way most of these devices do (as a storage device until disabled). I added a custom udev rule to invoke ‘eject /dev/sr1’, removing the usbseral driver, and reloading with ‘modprobe usbserial vendor=0x**** product=0x****’ as outlined manually here:
FWIW, I’ll include this old thread too:

I know there are several similar appraoches available. (I must admit I haven’t had to play with mobile broadband devices for a while now). It might take a bit of googling…
The driver is not responsible for the classification of the stick. Rather check hal and udev.
Just guessing … Maybe you can copy /lib/udev/rules.d/40-usb_modeswitch.rules to /etc/udev/rules.d and add the following line in this file:
# your modem description
ATTRS{idVendor}=="201e", ATTRS{idProduct}=="1008", RUN+="usb_modeswitch '%b/%k'"
I’m able to remove that driver in other distributions like Ubuntu 10.04 and Mandriva 2010 and use my usb-stick properly in it.
I tried this method and then observed the dmesg output. What i can get is that it gets connected temporarily as a ttyUSB0 device and then gets disconnected. This then continues like an infinite loop.
Well i followed those steps but i’m encountering the same problem. I’m getting temporarily attached and then disconnected. And then this continues like an endless loop.
I was able to make it work under openSUSE 11.2 as it was able to remove the usb-storage driver.
OK, then unloading the driver is a sensible workaround. However, the solution should be done udev.
Can you please post the dmesg output from the above attempt?
