Yes, really interesting. So I took your advice, and plugged the USB3 drive (which is a Toshiba 1GB HDD) in and saved the dmesg output and the fdisk list output. Neither show any indication of the drive. Now, if I plug another - non USB3 - drive in the USB3 (front) port, I immediately get a whole lot of output on the console terminal giving me information about the drive. If I plug the Toshiba USB3 drive in a back port, I get the same sort of information. So, as I said, the port is obviously working as a 'normal' USB port, and the Toshiba drive is obviously working as a 'normal' USB drive. It's just that combination of USB3 drive > USB3 (front) port that the box doesn't like!
Here's the fdisk output (I've cut out the mtdn blocks):
No /dev/sdc which is what I'd expect. Plug the drive in a back port and it appears in the fdisk listing as /dev/sdc
Reading through the dmesg output, there doesn't appear to be any reference to the Toshiba drive (which I suppose I'd expect. It's a very long file - can I send you the text output?)
As I say, not a show-stopper - more an irritation. Like an itch you have to scratch! But it would be interesting to know if it is a specific (drive? interface?) problem, or a more general issue.
And, as always, thanks so much for your help!
