I have attaxched 128GB USB SSD to my Bbox3. I can access files from bootcamp windows8 (via filemanager), but not from osx or parallels win8. Osx sees bbox3 on network places, but says" connection failed." I have also a network printer with sd slot, It can connect to it without problem. I have called proximus technicalservice, but trainee there has even no opinion about what NAS or Usb storage on bbox is!
