External USB hard drive rarely recognized/mounted

Post by SunDogBC »

I have no problems using 32GB flash drives as external storage. But when I try using a 232GB hard drive that is in an external enclosure, more often than not, I get nothing. It just says "No USB storage device is connected!".

It works when I plug it in to a Windows laptop and the flash drives do work so I know it's not a hardware issue with the external drive. I had used the drive in one of the drive bays and set it up as a new TNAS drive (since formatted blank) and it worked then. It's only when plugged into a USB port on the back that it doesn't work.

I'm not totally versed on this but running "lsusb" in a terminal does partially recognize it:

Code: Select all

Verbose output from "lsusb -s 2:51":

And finally, results from "lsusb -t":

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 480M
    |__ Port 4: Dev 2, If 0, Class=, Driver=usb-storage, 480M
It just doesn't mount it (or whatever comes next after seeing the device). Why might this be?
