DetachStorageOnly and HuaweiMode are exclusived?

Hi, all~
In the latest usb_modeswitch version 1.0.5, the source code
usb_modeswitch.c
line 437

specialMode = DetachStorageOnly + HuaweiMode + SierraMode + SonyMode;
	if ( specialMode > 1 ) {
		SHOW_PROGRESS("Invalid mode combination. Check your configuration. Aborting.\n\n");	
		exit(1);
	}

this will cause most Huawei product's config will not pass this check condition.
There are E169 and E220 in my hand, both can't work in this way.
Because I always use config to do mode switch, so when I update to version 1.0.5(from very old version 0.9.4@@), I find out this problem quickly.
Now my solution is to change config
DetachStorageOnly=1 => DetachStorageOnly=0

Is there any consideration on this check code?
If this is necessary, I suggest the usb_modeswitch.conf should also disable the Huawei product's DetachStorageOnly value.

thanks~

although I disable DetachStorageOnly, but I still can use pppd to dial up the modem.

The line "# choose one of these:" means that you have to to choose one and disable the other (delete or comment out).

The "special modes" should not be used in combination (won't make sense anyway), therefore the check.
