Re: usb device



Hello
It seems that my USB is recognized by the system. Still I can not mount the USB device. Indeed, when I type

mount /dev/sda /h/ -t vfat

I get the following message

mount: wrong fs type, bad option, bad superblock on /dev/sda,
      or too many mounted file systems

and when I type,

cat /proc/bus/usb/devices

I get the following output

Hello,
I am trying to mount my USB device but it is not really working!
When I type
mount /dev/sda1 /mount_point -t vfat
I get the following error message
mount: /dev/sda1 is not a valid block device
Does anyone know what is the problem?
Thanks!


It's not a valid block device ;-)

Are you sure it's sda1? Maybe the mass storage driver isn't loaded. Try

cat /proc/bus/usb/devices

Which will show you the info for the device as well as the driver that
picked it up.

You may want to also install (hotplug | hal | udev | dbus | gvm). I've been
very skeptical about this utopia stack but I have to admit that it works
extremely well.
