127 USB devices are supported by one host controller.

A typical modern motherboard has 1 IDE channel, which can support 2 devices. IDE has been replaced by Serial ATA (SATA), so modern boards have 2 to 8 SATA ports. Older motherboards may have 2 to 6 IDE channels, which could support 4-12 IDE devices.
Most modern SCSI buses support a total of 16 devices, while older SCSI implementations usually support only eight devices.
USB Will allow up to 127 devices per host controller. Usually, a host controller has more than one USB port. The host controller will only allow 127 devices in total (including hubs), so you can not have 127 per port.
you can have up to 7 and before some d*** goes it only has 4 lights and all this if you dont believe me look at some football games 1-7 players and go on a game hold in the button on the controller, settings change the number of the controller and you can go up to player 7 both 4 light and 3 light up :) The above answer is correct up to seven devices can be added and while they all don't have to be controllers they can be
A maximum of two devices can be placed on an EIDE / PATA cable. Not all cables will include two connectors for doing so, though.
AnswerA typical SCSI adapter have targets from t0 to t6 enabling to connect 7 devices. But t6 (last target) is reserved for controller itself so it limts the maximum devices to connect to 6.
One. SATA interfaces are USUALLY only one device at a time. It is possible, if the controller supports it, to use a port multiplier which allows you to use four devices off one port .
A personal computer external bus standard which can support up to 127 peripheral devices in a daisy chain configuration, can support plug-and-play (hot plugging), and has a total bandwidth of 1.5 megabytes per second. what are these devices?
Computer input devices are anything that allows a user to control a computer or inputs information into a computer. These devices may include your mouse, keyboard, or gaming controller. They may also include devices such as your microphone or camera.
