<![CDATA[USB Module with MAX3421E connect to 1D/2D/QR Barcode Scanner?]]>Hi,

I would like to know if the USB Module with MAX3421E will work with a 1D/2D/QR Barcode Scanner.

From my reading the USB Module with MAX3421E will work with ESP32 Basic Core Controller.

I would also need to store Barcode data to Flash as reference information. I would like to know if using the SPI Flash would conflict with using the USB Module which also use SPI.

Regards,
Markel
