Troubleshoot USB Reader Installation and Driver Issue

Step 1: Install Reader Driver

The 2018 and later versions of the eChain Desktop UHF RFID Reader uses the CP210x VCP Silicon Lab Virtual COM Port (VCP) driver for Windows.  Package version: 6.7.5, Release date:  2017-10-13.  Driver installation is necessary before using the reader.

OS VERSIONS:  Windows 10 (x86 32/64 bit), Windows 8.1 (x86 32/64 bit), Windows 8 (x86 32/64 bit), Windows 7 (x86 32/64 bit)

The VCP driver package contains the following files and directories:

• slabvcp.inf — Driver information file

### Prompted install ###

If Windows prompts you to install a driver for a CP210x device (for example, when you plug the reader into your computer):

1. Use the dialog to browse for the driver location
2. Locate the driver folder (that you previously downloaded from Dropbox location)
3. Follow the system prompts

### Manual install ###

1. Using Windows File Explorer, locate the driver folder (that you previously downloaded)
2. Determine if you have 32-bit or 64-bit Windows
3. Double-click to run the .exe file named CP210xVCPInstaller_xnn.exe
4. (where xnn is x64 for 64-bit and x86 is for 32-bit)
5. Follow the system prompts

### Device Manager Driver Installation ###

In case the Prompted or Manual driver installations are not successful, the below instructions will walk you through setting up the driver manually from Device Manager. This method works on PC’s running Windows 7.

Step 1: Confirm 32 bit vs 64 bit

Step 4: Note device driver did not successfully install

Step 5: Open Device Manager (while leaving RFID Reader connected)

• Start – Open Control Panel

Step 6: Note the problem device under Other Devices > CP2102N USB to UART Bridge Controller

Step 7: Right-click on the problem controller and click Update Driver Software

Step 8: Browse my computer for driver software (option)
