For sale is an I-O DATA USB2-SC USB 2.0 to SCSI Adapter, designed for connecting legacy SCSI devices such as hard drives, MO drives, optical drives, and scanners to computers equipped with USB.

This adapter supports up to four SCSI devices in a daisy-chain configuration and operates over USB 2.0 (backwards compatible with USB 1.1). Proper SCSI termination and configuration are required.

This is vintage interface hardware, originally produced for use with operating systems such as Windows 98 / ME / 2000 / XP and contemporaneous computers. While some users report successful operation on newer systems, compatibility with modern operating systems (including current versions of Windows, macOS, or Linux) is not guaranteed, and driver support on modern systems may be limited, unofficial, or dependent on third-party software.

Driver requirements vary by operating system and configuration:
  • Some Windows systems may function using built-in drivers, while others may require legacy drivers from I-O DATA.
  • macOS support depends heavily on OS version, device type, and software used.
  • Buyer is responsible for confirming driver availability and system compatibility before purchase.
The adapter is known (but not guaranteed) to have been used successfully by some users with certain devices when properly configured, including:
  • Nikon CoolScan III (with third-party scanning software such as VueScan)
  • EPSON GT-9500
  • EPSON GT-9600
  • EPSON ES-6000H
  • Olympus TurboMO640
These examples are provided for reference only and do not constitute a guarantee of compatibility.

Please note:
  • This item is not plug-and-play on modern systems.
  • Successful use requires legacy hardware knowledge, correct cabling and termination, appropriate drivers, and compatible software.
