Devices with fake driver CDs and how they are handled currently:
Zydas WLAN - kernel
Huawei 3G - kernel (unusual_devs entry)
Sierra 3G - kernel (drivers/usb/serial/sierra.c)
Option 3G - udev rules, 'rezero', or usb_modeswitch
ZTE 3G - udev rules, simple 'eject'
Some corrections:
* Huawei 3G: all devices that are handled in the kernel can be
switched outside too (usb_modeswitch). Newer Huawei devices have a
different mechanism which is so far only handled by usb_modeswitch.
* Sierra 3G: can be switched by usb_modeswitch as well.
* Option 3G: can be switched by usb_modeswitch (has been there for
quite a while before the kernel patch came in). One device family
needed a patch in the patch because the kernel switch affected the
wrong devices (ambiguous ID). These ambiguities can be handled by
usb_modeswitch by easily adding ID checks for SCSI_INQUIRY strings
and USB device data like "manufacturer", "vendor", "model" etc.
* ZTE 3G: some ZTE devices are using a different command than
"eject". Handled by usb_modeswitch.
The bottom line is that the imagination of the device developer has
no limit, so in my view - duct tape and libusb junk included - the
userspace is just able to react *a lot quicker* than the kernel space.
