iPod shuffle problems - usb-storage, ehci, scsi?

nitio · 11-18-2005, 01:55 PM

Hi all,
I've been having trouble with my iPod lately (both kernel 2.6.13 and 2.6.14).
I can find it in /dev/sda, I can mount, I can "everything".

I use gtkpod to update my songs, but that does not seems to be the case of the problems.
After some time plugged, modules loaded and mounter (maybe 2~3 minutes) looking at the kernel messages you will find this

Code:

As you can see, it gets an unknown error and so, it decides to reset. So as you guessed, it disable my device and find it again in a "higher" location (previsously sda, not sdb and so on).

It's impossible to use the iPod since it's not a matter of how much data I try to input at one time neither reading. It seems to be some event that the module receives and then it decides that since it's unknown, it should reset the device.

Has anyone had any of these problem? Solutions? Suggestions? Cry?
