The problem is not the cable or the port as it was fine when running stock image. I didn't try to transfer files on the internal storage though. But transferring multiple files to the sd card (ie. 11gb of pictures) hangs.. I had to split the transfer in multiple smaller ones. Once done, just listing the files takes forever! My sd card is a Samsung 64gb EVO Plus, which is fast enough. I tried to configure the sd card in both modes, internal and portable storage with the same result. So I ended up leaving it as portable storage and plug it with the adapter to my laptop to transfer the pictures and movies. In stock image, it didn't have an option to use it as internal or external.. or maybe is it just the drivers I installed to use with odin? I'll try to uninstall it to see if it changes anything.
