from your output, it's look like your modem vendor 12d1 and id 1001. find the default or storage product id.
DefaultVendor= 0x???? ;this is vendor for storage
DefaultProduct= 0x???? ;this is product id for storage
TargetVendor= 0x???? ;and this line and below belong to modem id.
if you done nothing before than lsusb, then that vendor and id belong to your storage default. then you must looking for modem id. because the vendor would be the same.
