THere are lots of different types of USB connectors and jacks.
In the synth world they are used for a wide variety of applications ... from simple power to data transfer
The jacks can be confusing
These were the first types
B is commonly called a printer USB cable.
A is still the most widely used type of jack.
USB-B micro is commonly found on lots of synths made in the past 5 years
though it seems to be fading out of popularity in favor of type C
This Expert Sleepers FH-1 is a midi host
It uses a Type-A USB connector for MIDI
This is a 2HP midi module
It uses a USB-B micro socket
The Roland JUo6A boutique synth also uses a USB port: MicroB type for Audio, MIDI.
Older android mobile phones like my Samsung galaxy note 5 used this connector.
THis has the advantage that you can plug your cable any orientation.
Most android mobile phones like my Samsung Galaxy 9 use this type of connector.
Many of these connectors supply power to your module.
It's handy to know what is what
The first two connectors (A + B) had just
four connections.
1 = +5V
2 = Data -
3 = Data +
4 = GND
The Mini & Micro cables added a 5th connector called
"ID". This helped distinguish cable ends.
So for the Mini/Micro USB A & B
1 = +5V
2 = Data -
3 = Data +
4 = ID
5 = GND This is the Teenage Enginering OP-z
It uses the Type-C connector
The OP-1 used type B-micro
