The wrong data is transmitted or data omission on USB-KBW mode

Sometimes the device transmits wrong data to upper computer or misses some data When it is on KBW mode, especially when the performance of upper computer is not very good. Because if the performance of upper computer is not very good, its speed of receiving data will be slow, at the same time the speed of sending data is fast on our devices, upper computer will be late to receive the data. So we can increase delay between the characters to slow down the speed of sending data. Take HR22 for example, you can scan below barcode to increase the delay.
