This type of cable is used for connecting certain devices with computer for data transfer or upgrading or restoring firmware. For example, I had a Android TV Box that had 4 USB ports, and one port could be connected to PC using USB A-Male to A-Male cable.
Accordingly, what is a USB to serial converter?
USB to serial adapters are cables that convert the data sent by a serial-enabled device for use by a USB port. The serial end has a DB9 connector, which plugs into the serial device.
Likewise, can you convert rs232 to USB?
Yes, a RS232 to USB converter does have a full-blown UART circuit built-in. As any standard UART, it does have Rx, Tx, and flow control pins. When data is there, the USB side returns the piece of data.
Is USB parallel or serial?
Note: Some older devices may have a USB 1.1/USB 2.0. The main difference between parallel (printer/LPT port; female) and serial (COM; male) ports is the data transmission. A parallel port transmits information in chunks (all eight bits of a byte at in parallel), whereas a serial port transmits one bit after another.
What happens if you plug a USB 2.0 into a USB 3.0 port?
You can plug a USB 2.0 device into a USB 3.0 port and it will always work, but it will only run at the speed of the USB 2.0 technology. So, if you plug a USB 3.0 flash drive into a USB 2.0 port, it would only run as quickly as the USB 2.0 port can transfer data and vice versa.
