5 Troubleshooting

5.1 Windows 10 cannot find drivers for my device

This error can occur if the VID and PID programmed into the device EEPROM do not match those

listed in the INF files for the driver. The VID and PID programmed into the device EEPROM may be

found by using the USBView utility from the FTDI web site. These can then be checked against the

VID and PID entries in the driver INF files. If they do not match, that driver cannot be installed for

that device without either re-programming the device EEPROM or modifying the list of VID and PID

numbers in the INF files.

Please note that only your own company VID and PID or FTDI's VID (0x0403) and associated PID

issued by FTDI for use by the customer should be used in the EEPROM and INF files.

End customers should obtain modified drivers from the OEM of the device, and not necessarily edit

the files themselves. If the FTDI driver files are edited in any way, the certification is invalidated

and the default drivers may not install.
