PL27A1 Super-Speed USB Host to Host Bridge Controller

The PL-27A1 is a single chip Super-Speed USB Host-to-Host bridge controller specially designed for Windows USB Easy Transfer cable and Microsoft Windows Easy Transfer program. The Windows Easy Transfer program is built inside Windows 7, Windows Vista OS and also available for Windows XP Update. Using the Windows Easy Transfer program, the PL-27A1 embedded USB Easy Transfer cable allows end-users to easily connect (thru the USB port) an old computer running Microsoft Windows XP or Win7 to another computer running Windows 7. Once the program has established connection for both computers, the end-user can then transfer large data files and program settings from the old computer to the new computer. It’s one of the fastest and easiest ways to transfer your files and settings to your new computer. The PL-27A1 embedded cable is fully supported by Microsoft for Windows 7, Vista and XP OS.
