1. A method in a data processing device, comprising:
- directing commands to device driver logic to a jump table, the jump table directing the commands to device driver command processing logic;
as a result of detecting a device error, reconfiguring the jump table to return without invoking the command processing logic and in a manner that indicates that the commands were successfully carried out.

Abstract
As a result of detecting a device error, calls to device driver logic are redirected to substantially reduce processing time of the driver logic and to return to the caller without providing an indication of the error.

5. A memory suitable for use by a data processing device, comprising:
-
logic to direct commands to device driver logic to a jump table, the jump table directing the commands to device driver command processing logic; and
logic to, as a result of detecting a device error, reconfigure the jump table to return without invoking the command processing logic and in a manner that indicates that the commands were successfully carried out. - View Dependent Claims (6, 7, 8)

9. A method comprising:
as a result of detecting an error, reconfiguring command routing logic for device driver logic 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. - View Dependent Claims (10, 11)
