Study Notes

Thunderbolt Overview

Developed by Intel and Apple, Thunderbolt is a high-speed, versatile interface combining data transfer, video output, and power delivery.
Released in 2011, subsequent releases have increased speed and functionality.
Features include daisy-chaining, backward compatibility with previous versions and USB standards, and support for multiple displays.

Thunderbolt Versions

Thunderbolt 1:
- Speed: Up to 10 Gbps.
- Video: DisplayPort 1.1.
- Cable Length: Up to 3 meters with copper cables.
Thunderbolt 2:
- Speed: 20 Gbps, combining two 10 Gbps channels.
- Video: Supports dual 4K displays.
- Cable Length: Up to 3 meters with copper cables.
Thunderbolt 3:
- Connector: USB-C.
- Speed: Up to 40 Gbps.
- Features: Supports charging (up to 100W), daisy chaining, multiple 4K displays, or one 5K display.
- Cable Length:
  - 0.5 meters for passive 40 Gbps cables.
  - Up to 2 meters for active cables.
  - Optical cables up to 60 meters.
Thunderbolt 4:
- Speed: 40 Gbps.
- Compatibility: Includes USB4, enhanced device compatibility, improved power delivery.
- Cable Length: Up to 2 meters with passive cables, longer with optical.
Thunderbolt 5:
- Speed: Up to 120 Gbps with dynamic bandwidth management.
- Features: Supports multiple high-resolution displays, enhanced charging (up to 240W).
- Cable Length: Active or optical cables recommended for longer distances.

Understanding USB

The core of USB is the USB host controller, an integrated circuit usually built into the motherboard chipset.
The host controller acts as the interface between the computer and every USB device connected to it.
Connected to the host controller is a USB root hub, providing the physical connection to the USB ports.
A single host controller supports up to 127 USB devices, though practical limitations exist.

USB Standards and Compatibility

USB Standards:
- USB 1.0/1.1: 1.5 Mbps (Low Speed)/ 12 Mbps (Full Speed)
- USB 2.0: 480 Mbps (High Speed)
- USB 3.0/3.1 Gen 1/3.2 Gen 1: 5 Gbps (SuperSpeed)
- USB 3.1 Gen 2/3.2 Gen 2: 10 Gbps (SuperSpeed+)
- USB 3.2 Gen 2x2: 20 Gbps
- USB4: Up to 40 Gbps
Connector Types: Type-A (rectangular), Type-B (square), Type-C (reversible oval), Mini and Micro USB (smaller devices).
Backward Compatibility: Newer USB versions generally work with older devices at the older standard's speed. USB-C supports various standards.

USB Endpoints

Communication channels within a USB device allowing data transfer between the host and the device.
Types:
- Control Endpoint: For device management and configuration, bidirectional.
- Isochronous Endpoint: Time-sensitive data transfer (audio, video), input or output.
- Bulk Endpoint: Large, non-time-sensitive data transfers (file transfers), input or output.
- Interrupt Endpoint: Quick, small data transfers (keyboards, mice), input or output.

USB Cables and Connectors

Original USB 1.1: Two types, A and B, in standard, mini, and micro sizes.
USB 3.0: Upgraded connectors to handle higher speeds.
USB 3.0 A and B: Use nine pins, compared to four in older USB versions.
Mini and Micro USB: Used for smaller devices, supporting data and power connections.

Troubleshooting USB Issues

General Issues:
- Check if the port is enabled in BIOS/UEFI.
- Enable or disable ports using Windows Device Manager.
- Check for driver issues.
Power Issues:
- Excess power draw can cause errors and malfunctioning devices.
- Disconnect devices or install a USB expansion card if necessary.
- USB selective suspend saves power by turning off USB power when the computer is shut down.
- Devices might not wake up if they are put to sleep to conserve power. Uncheck the "Allow the computer to turn off this device to save power" option in Device Manager.

Serial Ports

Legacy interface using RS232 standard (introduced in 1960).
9-pin, D-shell male socket, commonly called DB9 or RS232.
Not found on modern devices.
