The usbfilesystem object allows supported BrightSign players to expose a local file as a USB mass storage device when connected to a USB host port on another device (for example, a PC or television.) The host acts as if it is talking to a USB thumb drive or USB hard drive, but the reads and writes go to the specified local file on the BrightSign. Normally the local file would be prepared beforehand with a filesystem offline or using @brightsign/filesysteminfile on the player itself.

BrightSign players with USB-C (except for LS3 and LS4) can use this object.
