Ubuntu does not pick up USB drive

[djaychela]

OK, I have an Acer Aspire 3500 laptop that I'm running 10.04 on, pretty much everything works OK, and I don't appear to have any hardware problems (I've checked using Gnome Device Manager).

When I plug in a USB flash or hard drive, I don't get any drives/devices to mount, although in Gnome Device Manager the USB device appears as a USB Mass Storage Device.

Running tail -f /var/log/messages produces this:


Dec 10 19:44:31 darren-laptop kernel: [ 5800.632058] usb 1-3: new high speed USB device using ehci_hcd and address 4
Dec 10 19:44:31 darren-laptop kernel: [ 5800.765161] usb 1-3: configuration #1 chosen from 1 choice

And nothing else.

I'm not a newbie, but I'm stumped - I've done a fair bit of searching and found nothing other than modprobe instructions which don't work as it's not a module (and I'd like a permanent solution if possible)

Any help is appreciated.

check the usb device name with demsg or with fdisk -l and try mounting it by urself with mount

Hi.

I'd already tried that - the problem is that fdisk -l shows no difference in the device listings when the device is plugged in or not - I just get the sda1,sda2 and sda5 listings that are for my laptop's hard drive, so I assume that there's some behind-the-scenes work that creates these entries that my system isn't doing?

remove ur usb and demsg in terminal , attached usb device and demsg in terminal , what does it say ?

Hi.

You mean dmesg? It provides the same output as tail -f /var/log/messages, as above, with the "new high speed" and "configuration" lines, nothing else...
