Why is it needed? Are there devices that malfunction as modems while the
emulated cdrom is active?
I ask because I have tested a bunch of Huawei E226, which do have this
stupid cdrom emulation hack from hell to bypass Windows security policies.
While option does allow it to register the mass storage device with
usb-storage, it also works as a GSM modem just fine at the same time...
If there is a pressing need to disable that stupid emulated cdrom, maybe a
bug should be filled to fix it right in the kernel, so that the emulated
device is never bound to usb-storage to begin with?
