## Abstract

As a result of detecting an error, command routing logic for device driver logic is reconfigured so that command processing logic of the device driver is not invoked and to return from commands in a manner indicative of successful completion of command processing.

## Claims

### Claim 1

A method comprising:
as a result of detecting an error in a device driver command, reconfiguring command routing logic for device driver logic so that command processing logic of the device driver is not invoked and to return from the command in a manner indicative of successful completion of command processing.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
as a result of correction of the error, reconfiguring the command routing logic to invoke command processing logic of the driver logic in response to commands.
