Unsigned Files (hccoin.dll, usbechci.sys) After Upgrade
Anomaly:
Some files (hccoin.dll & usbechci.sys) may appear unsigned after an upgrade.
Description:
These two files may incorrectly appear as unsigned1, for example through the sigverif tool. They are in fact signed,
and this does not affect system functionality.
Systems Affected:
Compaq Evo D310 series, Compaq Evo D510 series, and Compaq Evo D320 series.
Resolution:
1. Right-click My Computer, and select Properties.
2. On the Hardware tab, click the Device Manager button.
3. Expand Universal Serial Bus Controllers by clicking on the sign.
4. Right-click the entry for Intel Enhanced Host Controller, and select Uninstall
5. Restart your computer, and allow the USB Host Controller to be redetected. The files will now correctly be
reported as signed.
6. Instead of restarting your computer, you may instead right-click the entry for Universal Serial Bus Controllers,
and select Scan for hardware changes.

Unsigned drivers are drivers that have not been officially approved by Microsoft. Device drivers that are "signed" have gone through the Microsoft testing and
approval process and are safe to run on your system. Microsoft recommends using "signed" drivers, since you know they have been tested and are from an
approved source.
