The USB version of the reader can be operated in two different modes:
HID ID TECH mode (HID Mode), Product ID: 2010
•
HID with Keyboard Emulation (KB Mode), Product ID: 2030

interference from other HID devices.

Card data is only sent to the host on the Interrupt In pipe using an Input Report. The reader will send
one Input Report per card swipe. If the host requests data from the reader when no data is available,
the reader will send a NAK to the host to indicate it has nothing to send.
