I have a usb hub from anker, and a seagate external hard disk attached to it,
for many years.
Numerous versions of mac os passed from my mbp without problems all the previous years.
But now, the last months, I can see that after some minutes, mac seem to lose 'connection' with the external hard disk.
Though it displays external hard disk and its contents as connected and visible/available, the reality is that they are not.
I just can't do anything with these files.
So I have to unplug, plug again, and then I gain some extra minutes before this problem appears again.
Is there any general problem with usb/ports/hubs etc, with big sur?
Does my problem reminds anything to you?
I hope this to be just a bug and be fixed soon.
But I wait for your opinions.
