Controlling HotPlug

Bugenhagen · 05-14-2007, 07:58 AM

Hi!

I have a Huawei E220 USB modem.
This is a serial unit with an internal "disk" with windows-drivers.

When I insert this, hotplug will load usb-storage, but not usb-serial.

How can I prevent hotplug from loading usb-storage for this device?
I'm not to keen of blacklisting the complete usb-storage module, but just for this device, with vendor=xxx and id=yyy.

If module is loaded, it is loaded for the whole system but not for specific device. I believe you can edit rc.hotplug (don't know which distro you are using) to make a check if this device is your modem and skip the loading. You can manually remove the module from memory with rmmod usb-storage. If you use 2.6 kernel, use udev.

Take a look, if you are running SUSE or RedHat, you should be able to fix it with UDEV rule included in the huawei.tar.bz2 package.

It works fine for both if you plug a usb-memory stick and Huawei E220 modem at the same time.
Yes, we can manage without blacklisting usb-storage

Have a lot of phun!
