Actually, the problem was neither in the desktop machine, nor in the USB HD. It got solved in the most curious of ways. One guy told me to try the HD not in the USB port on the front panel, but on the back of the cabinet, he said he has seen this happen. I did it, and that very moment it got connected and mounted. I don't know why. Maybe the amount of current supplied to the USB port in the front panel was inadequate for this high-speed USB HD. And I browsed the documentation of the motherboard. It is not there too, about any difference in the amount of electricity. But it happened. And maybe, because the current was inadequate, it was taking very very long for 'dmesg' to report the drive and its specification.
Pasting the 'dmesg' portion here, if it is of any help to anybody: [ 724.672031] usb 3-3: new high speed USB device using ehci_hcd and address 4 [ 724.805010] usb 3-3: configuration #1 chosen from 1 choice [ 724.950485] usbcore: registered new interface driver libusual [ 724.966149] Initializing USB Mass Storage driver...
