Zorluk: OrtaMobile Device Ports and Accessories

A technician is setting up smartphones for field staff who need to transfer large video logs directly to external high-speed storage drives. Although the smartphones use physical USB Type-C ports, the field staff report that transferring files using the manufacturer's bundled cable is unexpectedly slow, topping out at USB 2.0 speeds (480 Mbps). Which of the following best explains why the file transfer speeds are bottlenecked?

  1. The bundled cable is internally wired only for USB 2.0 signal lines despite having a physical USB Type-C connector.Cevap
  2. B
    The smartphone's USB Type-C port requires an active Thunderbolt converter to transfer files to external storage drives.
  3. C
    Direct physical file transfers are locked until the device is configured with a multi-device cloud synchronization account.
  4. D
    The mobile battery requires a full discharge calibration cycle to unlock maximum power delivery to peripheral storage devices.

Cevap

The bundled cable is internally wired only for USB 2.0 signal lines despite having a physical USB Type-C connector.
The correct answer correctly distinguishes between physical port geography and protocol capabilities. USB Type-C describes the 24-pin reversible connector shell, but cables bundled primarily for power delivery often omit the extra twisted pairs required for USB 3.x SuperSpeed modes, defaulting data transfers to legacy USB 2.0 speeds (480 Mbps).

Adım Adım Çözüm

1
Analyze the physical connector versus the data transmission protocol.
Recognize that USB Type-C specifies only the physical shell and pin layout, not the speed standard of the internal wires.
Manufacturers frequently supply USB-C cables bundled with mobile devices that contain only USB 2.0 data lines (SuperSpeed conductors omitted) to minimize cost while providing charging capability.
2
Evaluate the cause of the speed bottleneck.
Identify that a USB 3.x capable cable with SuperSpeed data lanes is required to achieve higher transfer rates.
Replacing the bundled charging cable with a rated USB 3.1/3.2 Gen 2 Type-C data cable unlocks the port's true bandwidth capabilities.
