The Blue-Point Microscan III (EESC720) is a powerful OBD2 scanner, but some users encounter “USB device not recognized” errors when connecting to a Windows 10 PC. This guide addresses common troubleshooting steps for establishing a successful connection.
Understanding the Blue-Point Microscan III USB Modes
The Microscan III features three primary USB connection modes accessible through its interface icons:
- Mass Storage Mode: This mode allows the scanner to function as a USB drive, enabling direct access to stored data.
- PC Communication Mode: (Typically the middle icon) This mode is specifically for communicating with a PC using software like ShopStream Connect. The “Do Not Power Down” message indicates the scanner is ready for PC connection.
- Settings Mode: This mode provides access to various configuration options, including touchscreen calibration. The “Do Not Power Down” message in a sub-menu likely signifies a firmware update process.
Troubleshooting the “USB Device Not Recognized” Error
If you encounter the “USB device not recognized” error, consider the following:
1. USB Connection Mode: Ensure the Microscan III is in PC Communication Mode (the middle icon). The “Do Not Power Down” message confirms the correct mode.
2. ShopStream Connect Software: Download and install the latest version of ShopStream Connect software from the official Snap-on website. Older versions might have compatibility issues.
3. Driver Installation: Windows 10 should automatically install the necessary drivers. If not, try manually updating the drivers through Device Manager. Look for unknown devices or devices with errors under “Universal Serial Bus controllers”.
4. USB Port Compatibility: While the Microscan III is compatible with both USB 2.0 and 3.0 ports, try different ports on your PC. Some USB 3.0 ports might have compatibility issues with older devices.
5. Cable Integrity: Inspect the USB cable for any damage. A faulty cable can prevent proper communication. Try a different known-good USB cable.
6. Scanner Firmware: Although the Microscan III indicates no updates found, ensure you are connected to the internet during the update check within ShopStream Connect. Occasionally, firmware updates resolve communication problems. Contact Snap-on support if you suspect a firmware issue.
7. Windows Updates: Ensure your Windows 10 operating system is up-to-date with the latest patches and drivers. This can often resolve underlying USB communication issues.
Accessing Microscan III Data on PC
Once connected, ShopStream Connect should recognize the Microscan III and allow access to its data. The scanner won’t appear as a separate drive letter like a typical USB drive in Mass Storage Mode. ShopStream Connect software manages the data transfer and storage. Consult the ShopStream Connect user manual for specific instructions on retrieving and viewing diagnostic data.
In conclusion, connecting your Blue-Point Microscan III to a Windows 10 PC should be straightforward. By understanding the scanner’s USB modes and following these troubleshooting steps, you can overcome the “USB device not recognized” error and access the valuable diagnostic information stored within your scanner. If problems persist, contacting Snap-on technical support is recommended.
