Comment 12 for bug 236422

I am having the same problem with my Sansa e260, which was working just fine as a USB storage device under Ubuntu 8.10, but since switching to Kubuntu 9.04 and KDE 4.2, it won't mount consistently. (It worked once a few days ago, but not since.)

If I tail /var/log/messages when I plug it in, I can see it getting detected:

...kernel: [ 519.384118] usb 1-4: new high speed USB device using ehci_hcd and address 7
...kernel: [ 519.520350] usb 1-4: configuration #128 chosen from 1 choice
...kernel: [ 519.552853] scsi11 : SCSI emulation for USB Mass Storage devices
...kernel: [ 529.928151] usb 1-4: reset high speed USB device using ehci_hcd and address 7
...kernel: [ 530.076366] scsi12 : SCSI emulation for USB Mass Storage devices

One strange thing here is the "reset" that happens ten seconds later. I don't know what that's all about.

I can also see it in lsusb:

...
Bus 001 Device 007: ID 0781:7421 SanDisk Corp. Sansa E200 series
...

But it doesn't show up in the KDE device notifier at all.
