My Galaxy Spica needs this quirk when in modem mode, otherwise it causes endless USB bus resets and is unusable in this mode. Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500 for the modem part. That's why in addition to this patch the visor driver must be prevented from binding to SPH-I500 ID, so ACM driver can do that.
