the module has a thingy that transfers it into data!!!!!
USB supports several communication modes, primarily including control, bulk, isochronous, and interrupt transfers. Control transfers are used for device configuration and command, while bulk transfers handle large amounts of data without time constraints. Isochronous transfers provide time-sensitive data delivery, making them suitable for applications like audio and video. Interrupt transfers are used for devices requiring timely delivery of small amounts of data, such as keyboards and mice.
