It's just very slow. You also need to enable Smb1 in W10 as it is disabled by default.
If you are not worried about speed, the port works ok, I use it to connect an external hard drive for backups.
How slow are we talking, and is there any hope they will enable SMB2 or anything better?
I was going to use it to connect a hdd to my laptop wirelessly for occasional data transfer / backups, so slow wouldnt be a problem unless its like 50kbps lol
I guess it depends on the number and size of the files being transferred as much as the total size, but somewhere between about 40Mbs and 64Mbs. A 169GB backup took about 8.5Hrs and a 10.5GB about 20 mins.
Pretty sure it is a USB2 port, however as with earlier BT Hubs it will run much faster if you plug in a USB3 drive.
