USB: allow usbstorage to have LUNS greater than 2Tb Attached is a very small patch (several comment lines) and a one-line coded change) that allows for USB storage devices that are larger than 2TB. At the company where I work we need such support, and one of my co-workers, Jane Liu, pointed out that SCSI low-layer drivers need to specify what size CDBs they accept. After looking through the code it became obvious that the current USB Storage code accepted the default of 12-byte CDBs, so I changed it to accept 16-byte CDBs. This allows our device to work.
