Please add the following line to the list of supported USB devices:

|| Transcend Portable SSD ESD230C || ? || 0x2174:0x2000 || Transcend /
StoreJet Transcend || -d sat || Linux / Windows || oki684 || Silicon
Image based SSD ||

change: Transcend Portable SSD ESD230C added, USB ID 0x2174:0x2000

It works with smartctl 7.1 out of the box, no need to specify "-d sat".
