I need your help, please.
Study case :
* I developt a program with an Adruino MKR 1010
* I connected a DS9808 scanner to the USBHost
* With the DS9808, it beeps and scan every thing. The program and scanner works
* With the DS9908 (new one), it doesn't Power ON, no wake up
* I have two DS9908, and all them power OFF
The configuration of each reader is the same : HID keyboard with power management
All scanners work on my PC.
