Some USB ports (especially USB 3.0 vs. USB 2.0) handle low-level device descriptors differently. Changing ports can sometimes change how the dongle’s hardware information is reported. Additionally, using a USB hub (powered or unpowered) may alter timing, leading to a mismatched read.
Windows may have updated its USB drivers, or the Autodata-specific drivers have become corrupted. This can alter how the system reads the dongle’s hardware ID.
If all software steps fail, the dongle may be defective or a counterfeit. Some USB ports (especially USB 3
If you use Autodata (a widely used automotive diagnostic and repair information system), you may encounter Error Code 345 during installation, software startup, or when attempting to access certain features. The full message typically reads:
“The hardware information does not match with your dongle link.” If you use Autodata (a widely used automotive
This error indicates a security validation failure between the software and its USB hardware dongle (license key). Below is a detailed breakdown of what causes it and how to resolve it.
Autodata uses a physical USB dongle (similar to a flash drive) as a copy-protection mechanism. The dongle stores unique hardware identifiers tied to your specific license. When the software runs, it compares the current system’s hardware information (e.g., motherboard serial number, hard disk ID, or network adapter MAC address) with the data encrypted inside the dongle. “The hardware information does not match with your
Error 345 occurs when the software detects a mismatch — meaning the dongle was originally linked to a different computer or hardware configuration than the one it is currently plugged into.
The most straightforward cause. You may have accidentally plugged in a dongle from another vehicle manufacturer’s diagnostic system, an older Autodata version, or a colleague’s dongle that isn’t licensed for your subscription.
