Error using instrument/delete (line 82)
Operation failed: An error occurred while executing the driver disconnect code.
OmniDriver was not found or could not be loaded. Possible reasons are javaclasspath.txt or classpath.txt is not configured
properly to load OmniDriver.
If this error is not an instrument error, use MIDEDIT to inspect the driver.

Error in icdevice (line 308)
