11.14.2 USB Mass Storage (Thumb Drive)
USB memory devices are supported and work with Micro Framework file system, please
refer to Storage Devices section for reference.
11.14.3 USB-To-Serial Device
● USB-To-Serial FTDI
● USB-To-Serial Prolific
● USB-To-Serial SiLabs
● USB-To-Serial Communication Device Class (CDC) modem
● USB Sierra C885 3G modem
These devices can be connected to Embedded Master and are handled similar to physical
COM ports. Some of them cannot be recognized by Embedded Master but you can still
force Embedded Master to recognize them as in examples below. Also, there are two
Prolific drivers for different versions of the hardware. If one of them does not work, you can
force Embedded Master to use the other one.
Example
Connecting a FTDI and SiLabs serial devices. Embedded Master recognized the FTDI but
not the SiLabs one. Therefore, we will force Embedded Master to use the SiLabs driver.
