I have a 256 MB mp3 player that works "out of the box" in Mandrake (same system). In Kubuntu it intially didnt work as use-storage wasnt loaded. So i modprobed that and then plugged in and got this error

And that continues on for several more lines there.
It, of course, never gets mounted and even fdisk -l doesnt display it on the system.
Its probably not a Kubuntu only problem, but as it works fine in Mandriva i thought i would start here.
try to use mount /dev/sda or /dev/sda2 to load it, if it didn't load automatically. Make sure they are connected well. If that fails then try to refresh hotplug sudo /etc/init.d/hotplug restart. And if that fails then reboot your computer and leaving the mp3 player plugged in and let hotplug make an entry for it and find it at the boot. That used to be the workaround for ubuntu 4.10 for me and my ipod mini without having to redo a new kernel to disable one option.

Ok well if your sda/sda2 devices don't exist you wil have to make them.
1. cd /dev/
2. Execute sudo MAKEDEV sda
3. And then restart your computer by typing sudo init 6
4. When your computer restarts plug in your device and wait for the hotplug script to find it when it boots.
5. If in case it was not found during the boot you can always try to edit /etc/fstab. But that should make it work. I had the same issue with Ubuntu 4.10 and the iPOD mini.
Still concerns me that i am getting I/O errors. Makes me think that the kernel is misisng something to coomunicate with this device.
I know fstab wont help here as the kernel ishaving trouble recognising it as a block device.
There might be a problem with the kernel, apparently its something to do with the recognition of partitions I read something about it on the Ubuntu 4.10 forums. This was an issue with the iPOD, and people's work around was to recompile the kernel without that partition recognition option.
Originally posted by DaveQB It seems i havent ehci_hcd mod loaded
Sorry I couldn't help, I feel your pain. Took me about 2 weeks of googling and a lot of failed attempts to mount my player, and then i just stumbled on some post about ehci_hcd module and scii usb drives and tried that.
Well tried Mepis 3.3.1 and same deal, heaps and heaps and heaps of I/O errors and buffer errors.
Plugged the same device into my Mandriva 2005 Desktop and dmesg reports

And KDE puts an icon on the desktop
Mepis is using kernel 2.6.10
My Desktop is using 2.6.11 but was using a 2.6.8 and it worked fine there too.
Seems Debian based distro's are out of the question for me on this laptop.
I have just applied the patch to the kernel sources in Slack and compiling as we speak.
PS thank god for distcc otherwise this would be taking me forever on a PIII 600mhz
PSS i checked the kernel source for my Mandrake system and the patch wasnt there. So I have no idea how Mandrake gets this thing working so flawlessly.
