USB Polling Interval
This option speeds up the USB Keyboard HID Device. Scan one of the following bar codes to set the polling
interval, which is the rate at which data can be sent between the image and the host computer. A lower number
indicates a faster data rate. The default is 3 msec.
Changing the polling interval re-initializes the imager.
CAUTION Ensure the host can support the selected data rate. Selecting a data rate that is too fast for the host
may result in lost data.
