=== Device usage ===
The USB ports can be used under Linux for connecting USB devices: the related device driver has to be integrated into the Linux kernel.
To connect USB devices to the debug serial portJ3 an [https: # connect //www.digikey.it/product-detail/it/tripp-lite/U460-T04-2A2C-1/95-U460-T04-2A2C-1-ND/10269263 USB-C HUB] has to be used for power the DB9 adapter bracket to Evaluation Kit while transferring USB data. Please check that the J22 connector on chosen HUB is qualified for the SBCX board# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1Power Delivery protocol.
