The dwMechanical field is a number value from the CCID USB descriptor:
The value is a bitwise OR operation performed on the following values:A footnote in the specification also indicates:
• 00000000h No special characteristics
• 00000001h Card accept mechanism
• 00000002h Card ejection mechanism
• 00000004h Card capture mechanism
• 00000008h Card lock/unlock mechanism
These mechanisms of the dwMechanical parameter have been included for completeness; however, these functions of motorized CCIDs are not covered by this release of the specification. A future release may attempt to standardize the interface to these mechanical functions.
The normal value should be 0x00000000: "No special characteristics" since this field is not covered by the CCID specification.
