Supports common USB devices: printer, U shield, and mobile hard disk Key benefits Expand device capability: lets your system use external USB peripherals for printing and file storage without complicated setups. Simplifies data access: read, write, and transfer files directly from U shields and mobile hard disks to your host device. Practical for work and backup: enables ondemand printing and straightforward external storage for documents, photos, and large files. What it does Function: provides USB device support so connected printers, U shields, and mobile hard disks can be used by the host system. Compatibility: works with standard USB peripherals listed above; compatibility depends on the connected device and the host system's USB interface and drivers. Performance and reliability: designed to enable normal USB device operation; actual transfer speeds and behavior follow the specifications of the connected peripherals and host. Use scenarios Office printing: connect a supported printer to produce reports, invoices, or meeting materials directly from the host device. File transfer from U shield: access or transfer presentations and documents stored on a U shield for immediate use or editing. External backup and media access: read or back up large photo and video collections from a mobile hard disk without relying on network storage. Practical notes Confirm your host system supports the connected USB device and any required drivers. Performance (transfer speed, responsiveness) will depend on the specific printer or storage device and the host's USB capabilities. Clear, dependable support for printers, U shields, and mobile hard disks to extend your device's printing and storage functions.
