The cause of the problem is that I selected GPIO0 as SPI slave select at USBv1.2 module.

I just modified the HID mouse example program. It works for my requirements.

Hi,

I have a Core2 for AWS and USB v1.2 module. I am going to connect USB 1D/2D barcode reader to it. The HID Keyboard example program will work for barcode reader. What example program from this library should I use? https://github.com/m5stack/M5-Max3421E-USBShield/tree/master

It still happens. Any permanent solution to the problem>

Hi,

Using Arduino IDE I am able to program hello example program with M5Stack Core 2 for AWS and M5GO Bottom2 for AWS connected.

However, with M5Stack Core 2 for AWS and USB v1.2 module. I get error "Failed to connect to ESP32: Wrong boot mode detected (0x17)! The chip needs to be in download mode".

How do I solve this problem?

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.
