NOTE PRO- How to Download large numbers of PDFs to

Hi Everyone,

I just got a new Boox Note Pro.
There is no online manual on the Onyx website that I can see—surprisingly!!

Therefore: does anyone know whether you can use a usb device to download files to the note pro?

(Also, using Chrome my Note Pro is unable to search the internet when connected to Starbuck’s wifi (even with all bars). Does anyone know what the issue there is? )

Thanks in advance.
