Anonymized repair experience
Case examples are based on real repair work and are intentionally stripped of customer-identifying information. Some examples predate the VA Computer Repair brand.
A real repair pattern
- An Epson ES-C220 scanner repeatedly stopped connecting on Windows 11. Uninstalling and reinstalling made it work, but the problem later returned.
- The next round of troubleshooting disabled USB selective suspend and USB hub power saving, then restarted the Windows Image Acquisition service. The scanner responded again without another full reinstall.
Check USB power management
- Windows can suspend USB devices or hubs to save power.
- For devices that must remain reliably available, test with USB selective suspend disabled and disable “Allow the computer to turn off this device to save power” on the relevant USB hub where appropriate.
Restart Windows Image Acquisition
- WIA is a Windows service used by many scanners and imaging devices.
- Stopping and starting the service can restore communication when the hardware remains visible but scanning software cannot use it.
Do not overlook the basics
- Try another USB port and cable.
- Confirm the device remains visible in Device Manager.
- Install the manufacturer’s current software.
- Avoid stacking multiple old scanner packages that may compete for the device.
Bottom line
When reinstalling only fixes the scanner temporarily, power management and Windows imaging services can be more important than reinstalling the same driver again.
