Comment # 6 on bug 905893 from Bruno Pesavento

This may be a duplicate of bug903753: usb_modeswitch still in 13.2 OSS repo is
broken. Use version 2.2.0-7.1 in HW repo instead.
@Joachim: the e160 may be of an early huawei type that switches by
disconnecting, like the e220, e156 etc.
I used those with 12.2, but never worked with kernels 3.x.
The problem is that _both_ usbstorage _and_ option modules try to switch them
out of cd-mode. Blacklisting usbstorage is a workaround, but you lose the
internal microSD.
