Why Integrate Eltima’s USB Pass-through Technology (UPT)?

Advanced USB pass-through technology by Eltima Software is designed to help cloud service providers redirect any peripheral USB device from a user’s local machine to the cloud over network. USB “plug and use” is every cloud platform user’s dream and integration of USB passthrough is the best way to make it happen. Improved with the USB passthrough technology, the cloud platform offers its customers an ideal solution for accessing USB devices right from a cloud infrastructure.

USB Pass-through Technology

Use cases when cloud platforms need USB pass through support:

  • printing from cloud servers to local corporate photocopiers, printers, and faxes;
  • accessing local software dongles from cloud platforms;
  • using a cloud server for scanning from a local scanner;
  • forwarding USB controllers to a cloud infrastructure to play cloud computer games;
  • scanning fingerprints by redirecting the image processing and control to a cloud platform;
  • interacting with iPhone, Android, and Microchip via the cloud for their programming and testing;
  • managing Point of Sales Terminals in a cloud infrastructure, etc.

The USB passthrough support can be integrated into the cloud platform with the help of USB pass through Technology SDK. This SDK is made available in only to our partners in form of OEM or source code license. Let’s take a look at the contents of the SDK:
