On 18 July 2011, Alverson released a Universal Binary version 1.2 that runs on Mac OS X 10.4 through Mac OS X 10.14. Because this version is not 64-bit, however, ZTerm will not run on Mac OS X 10.15 and above. On modern machines without built-in serial ports, ZTerm can identify and use a wide variety of USB-based serial devices. [6]
An USB device can be located by the bus:device address, or by the hub:port address. [16] Also, after the descriptors is retrieved, the host performs another control transfer exchange, but instead to set the address of the USB device to a new ADDRx.
A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232 , RS-485 , RS-422 , or TTL-level UART serial data.
The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port. High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. There may be one translator per hub or per port.
Finally the call device.controlTransferOut() will set up the device to communicate through the WebUSB Serial API. Once the set up is all done, data can be transferred to the device using device.transferIn() to transfer bulk data to the device, similarly its sister function device.transferOut() to read data from the device.

Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is for power and data transfer, the other solely for power, which makes the device a non-standard USB device. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the ...
Almost all ports on personal computers are hot-swappable. Plug-and-play ports are designed so that the connected devices automatically start handshaking as soon as the hot-swapping is done. USB ports and FireWire ports are plug-and-play. Auto-detect or auto-detection ports are usually plug-and-play, but they offer another type of convenience.
On the rear of the display is a Thunderbolt port, a FireWire 800 port, three USB 2.0 ports, and a Gigabit Ethernet port. The Thunderbolt port allows for the possibility of daisy chaining Thunderbolt Displays from a supported Mac, or connecting other devices that have Thunderbolt ports, such as external hard drives and video capture devices.
