I've acquired a Sheevaplug running - I think - Ubuntu. I'd like to mount an external USB hard drive, but I don't know the name of the device that needs mounting.

When I list the devices under /dev, a long list is produced.

How do I find out which device listed needs to be mounted?

Update:

When I run dmesg after plugging the device in, I see the following at the end:

usb 1-1: new high speed USB device using ehci_marvell and address 6
usb 1-1: device not accepting address 6, error -71
usb 1-1: new high speed USB device using ehci_marvell and address 7
usb 1-1: device not accepting address 7, error -71
usb 1-1: new high speed USB device using ehci_marvell and address 8
usb 1-1: device not accepting address 8, error -71 
usb 1-1: new high speed USB device using ehci_marvell and address 9
usb 1-1: device not accepting address 9, error -71

And when I view /var/log/messages, I can see this:

Sep 23 21:26:03 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Sep 23 21:26:04 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$

Unfortunately, I don't know what these mean.

Sheevaplug devices can run a variety of operating systems. If the device is running a Linux distribution, you should be able to use these methods:

When you plug in the device, a message should appear in the system log - probably in /var/log/messages. From this you should be able to determine the device name.

You can use dmesg to view kernel messages.

You can use lsusb to get details of USB devices


Error messages such as "device not accepting address" ... "error -71" suggest a hardware problem, I'd try a different USB cable, a different USB port (if available), a powered USB hub, direct power to the drive (from an appropriate external PSU) etc.
