Hi,
I have an existing project running on a Teensy 3.2 which receives commands from a PC connected via USB through a second USB port that is a FT232RL USB to TTL Serial Adapter Module connected to the Teensy I/O.
The reason for using a second USB port on the Teensy 3.2 is so that the primary/built in port can be used to update the firmware and also drive a serial console that shows the status / debug.
I need to make a new system so am thinking that i can use a Teensy 4 which includes a secondary USB port.
My question is can the second USB port on a Teensy 4 be used as a standard USB port to receive commands from a PC (thus negating the need to use a FT232RL USB to TTL Serial Adapter Module connected to the Teensy I/O like i do with the Teensy 3.2).
The documentation refers to the port as "USB Host" which infers that it intended to be a USB controller device rather than a listener (hope that makes sense)
Are there any other components needed to use the second USB port on the T4 other than a physical port connector ?
Many Thanks
Jay
