The dwDataRate field is a number value from the CCID USB descriptor:
The default data rate is the data rate used before a new data rate is selected by the reader and/or the driver.
Most of the values are around 9600 bps which is the historical data rate value.
The 3 readers with dwDataRate = 106000 bauds are contactless readers.
The dwDataRate field is a number value from the CCID USB descriptor:
Default ICC I/O data rate in bps. This is an integer value
Example: 9600 bps is encoded as the integer value 9600. (00002580h)
