Was glad to see a USB port on the PowerHub. To test I added a 32GB usb2 stick NTFS. On Windows it was easy to map it as a network drive.
On Android using the X-plore File Manager, tapped LAN and then Add server, and added these entries:
Label: USB on PowerHub
Path: Sandisk_UltraUSB30_1_6320
Server: vodafone.powerhub (also tried 192.168.1.1)
Username: admin
Password: same as the Router
Domain: Vodafone (also tried Workgroup)
Untick SMB2 (also tried it ticked)
Test: Message: "SMB Bad network name"
After saving and opening it, message: "No files to show"
Would appreciate suggestions!
