Hi using ubuntu 10,04 I am trying to copy data to a sansa clip usb mp3 player if I plug it in as me, then it sometimes mounts and I can view the data on it, however it does not always mount properly or seems to randomly disconnect and the icon is removed from the desktop my user is a admin user on ubuntu, if i try and plug it in as a normal user nothing seems to happen at all with the music device, the external hard disk seems well behaved for the most part.
Not sure on that, I wonder if it maybe presents itself as something other than a mass storage device? (I know some older Philips MP3 players do this).
i also have a usb hard disk which if plugged in to the desktop system, directly mounts, if I try and plug this in to the usb external hub it won't mount,
Is it a powered hard drive (i.e. 3.5" external hard drive with separate power supply) or a 2.5" USB powered drive?
You'll probably find that unless the USB hub is powered itself it won't provide enough power for a 2.5" external hard drive.
if I try and plug both devices in to the external hub i get either one or the other mounting, but not both if they are both plugged in
Hmmm, okay could be completely off on my above suggestion. Not sure why.
are there issues with dbus that can cause problems
Not sure.
what has changed in terms of the content of /media it used to have folders which I now understand are dynamically created.
Yep, it's been like that for a while. I've found that on some versions it'll mount the drive as the UUID of the drive and other times as the volume label of the drive (although that could be down to the drives I've been trying).
before we had folders that acted as mount points, something has changed between 10.04 and earlier versions in the way ubuntu handles things I am getting lots of messages referring to dbus, so not sure if there are know bugs in that.
Might help if you can post the error message you're getting.
I am really really struggling to explain exactly what the situation is as to me it seems random, sometimes I can plug the music device in and it works. It just seems to randomly work, i am worried as to why something would just unmount for no aparent reason (or appear to)
Dodgy connection? Faulty device?I have a USB cable which has the same issue, if I plug something in it will work and then stop working.
i did manage to get both working, and tried to copied 2 folders of music across to the player only half way through the copy dialog seemed to be stalled, so after a while i ended it, and tried to unmount, i then got another dialog saying it was writing remaining data, which again didn't seem to be doing much, just displaying a status box with another bar moving back and forth quickly.
Hmmm, does it work when you copy data from say the hard drive to your internal drive and then onto the music player from the internal drive?
has anyone else had any issues trying to plug in two usb storage devices.
Nope, works fine for me on Ubuntu 10.04. Rob -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
