Subject: Sansa Connect: Initial TNETV105 driver port

Port USB driver from Sansa Connect Linux kernel sources. The device
successfully enumerates and responds to SCSI commands but actual disk
access does not work. The SCSI response sent to host mentions that both
internal storage and microsd card are not present.
