### Error message: Device driver initialization failure

When you attempt to open a Digi port, you get an error message stating the device driver initialization has failed.

Cause | Resolution
--- | ---
The configuration of the device driver may not match the configuration of the adapter. | Do the following: Complete the software installation. Verify the I/O port address assigned by Windows matches the address set on the Digi ISA adapter's DIP switches. If they are not the same you will need to modify the settings. Go to Reconfiguring Input/Output Range. If after performing the above procedure you again receive the same error message, go to Reconfiguring Memory Range. If the first two procedures fail to resolve the hardware conflict and you again receive the same error message, go to Reconfiguring the Interrupt Request Settings.] In the event all troubleshooting procedures fail, call Digi technical support.
