I have an external USB hard drive that sometimes gives the following error messages in dmesg when I plug it in. When this happens, the drive does not show up under lsusb, and obviously the drive cannot be mounted. [   62.087109] usb 1-1.1: new full-speed USB device number 4 using ehci-pci[   62.159098] usb 1-1.1: device descriptor read/64, error -32[   62.335103] usb 1-1.1: device descriptor read/64, error -32[   62.511079] usb 1-1.1: new full-speed USB device number 5 using ehci-pci[   62.583081] usb 1-1.1: device descriptor read/64, error -32[   62.759067] usb 1-1.1: device descriptor read/64, error -32[   62.935064] usb 1-1.1: new full-speed USB device number 6 using ehci-pci[   63.343027] usb 1-1.1: device not accepting address 6, error -32[   63.415020] usb 1-1.1: new full-speed USB device number 7 using ehci-pci[   63.822913] usb 1-1.1: device not accepting address 7, error -32[   63.823201] usb 1-1-port1: unable to enumerate USB deviceWhat does this mean? Is the drive starting to fail?
