If you’re experiencing issues with your Usb Link2, the problem might stem from your Windows PC and its drivers. Trying the USB Link2 on another computer can help isolate the issue. If the problem persists, reinstalling the NXP drivers for the Link2 may be necessary.
Understanding NXP Driver Files for USB Link2
Windows uses driver files with the extension “.inf” to manage connected devices. These files contain information about the device’s vendor ID (VID), product ID (PID), and other crucial details required for proper functionality. For NXP devices, including the USB Link2, the VID is typically “1FC9”. You can identify relevant driver files by searching for this VID within the Windows INF directory.
A simple command line search using pnputil.exe or fgrep within the C:\Windows\INF directory can reveal which files contain information related to NXP devices: fgrep -i 1fc9 *.inf
This search will output lines from various .inf files, each referencing different NXP devices with their respective PIDs and sometimes MI (Multiple Interface) numbers. For example, an entry like:
oem64.inf:%LINK2VCOM%=LPCVCOM,USB\VID_1FC9&PID_0090&MI_01
indicates that the file oem64.inf contains information related to a USB Link2 device (identified by the string “LINK2VCOM”) with VID 1FC9, PID 0090, and MI 01. This signifies a specific configuration of the USB Link2. Other PIDs and MIs represent different functionalities or versions of the device.
Uninstalling and Reinstalling NXP USB Link2 Drivers
Identifying the correct .inf file is crucial for driver reinstallation. While multiple files might contain the “1FC9” VID, the specific PID and MI for your USB Link2 will pinpoint the correct driver.
Before reinstalling, it’s recommended to uninstall the existing drivers. Use the Windows Device Manager to locate the USB Link2, right-click, and select “Uninstall device”. Ensure you select the option to delete the driver software if prompted.
After uninstalling, you can attempt to reinstall the drivers automatically by restarting your computer. Windows will typically attempt to find and install the appropriate drivers.
If automatic reinstallation fails, you can manually install the drivers using the .inf file identified earlier. Locate the relevant .inf file in the C:\Windows\INF directory, right-click, and select “Install”.
Conclusion: Resolving USB Link2 Driver Issues
By understanding the relationship between .inf files, VIDs, PIDs, and how they relate to your USB Link2, you can effectively troubleshoot driver issues. Utilizing command line tools to search for relevant files and properly uninstalling and reinstalling drivers can often resolve connection problems and ensure optimal functionality of your USB Link2 device.
