What is USB Duet?

USB Duet connects a netbook PC to another PC with a USB cable

This allows users to

  • Share another PC's optical disc drive (ODD) to install software, burn or rip CD/DVDs, perform HDD recovery, and upgrade OS
  • Connect to another PC for file sharing and sync
  • Connect to iPad, HDTVs, printers, gaming consoles, DVD players, and more!

Key Features & Applications

Key Features

  • 480Mb/s up to 5Gb/s performance!
  • Secure connection
  • Simple to use, "It just works!"

Key Applications

  • Optical Disc Drive (ODD) Sharing
  • File Sharing
  • System Setup & Recovery
Optical Disc Drive (ODD) Sharing

Share another PC's optical disc drive (ODD) with the netbook PC to allow users to

  • Install new software from a CD-ROM disc (e.g. MS Office)
  • Burn media and data files from the netbook PC directly to CD or DVD discs
  • Recover the netbook PC's HDD using a recovery DVD
  • Upgrade the netbook PC's OS with an install DVD-ROM disc

ODD Sharing provides end user cost savings because they will not need to buy an external ODD for their netbook PC

File Sharing

Share files using a virtual USB thumb drive that resides on the netbook PC

  • User chooses what files to put in the virtual drive for sharing
  • Connect the USB cable and virtual drive appears on the other PC
  • Directly connect to HDTVs, DVD players, and Gaming Consoles, and to share media files (e.g. play slideshow)

Security prevents access to virtual drive when netbook PC is in these modes: Log Off, Locked, Sleep/Hibernate, Shutdown. File sharing is supported in Windows (XP, Vista, 7) as well as certain instant-ON OS (for quick sharing).

System Setup & Recovery

Enhances the "Out-of-the-Box Experience" (OOBE) for consumers setting up a new netbook

  • Connect new netbook to existing PC to migrate settings, bookmarks, music, pictures, etc. to the new netbook PC

Backup/Restore netbook PC's entire HDD or partition(s) to/from another PC

  • Connects like an external HDD to another PC
  • User recovers HDD image using a recovery DVD-ROM disc
  • Increased HDD Storage Space
  • No need to store recovery HDD image on netbook PC HDD

Applications Expansion

Infinite possibilities for new apps in Intel Netbook App Store. Developers can develop new apps to work on USB Duet-enabled netbook PCs and post them on the Intel Netbook App Store for purchase.

New apps ideas include...

  • Internet Connection Sharing
  • KVM - Share primary PC's keyboard, mouse, and monitor for more comfortable use at home/office
  • Outlook Sync - Sync Outlook and My Documents data to and from a user's primary PC
