[gentoo-user] Error using "safely remove" for every USB DEVICE.

Hello Mates,

I'm getting this error: http://img684.imageshack.us/img684/5359/usberror.jpg

Everytime I try to use: "Safely Remove" option, in every USB device, I'm
not losing data -I guess- because I have not noticed, but, I really don't
know why is this happening, and well.. I would like to know if there any
way to fix it, and why is this happening. (I've already googled, nothing
interesting).

Regards,

Hello Carlos,

this error is just telling you that udisks did not succeed in powering
down the USB device, but actually it was unmounted cleanly (so no data
will be lost).

The reason is most likely a missing kernel option:

"USB runtime power management (autosuspend) and wakeup" in "Device
Drivers" -> "USB support".
Note that this option only shows up when "Run-time PM core
functionality" in "Power management and ACPI options" is enabled.

Maybe someone could make the ebuild check for this option and issue a
warning if it is unset?

Regards,
Felix

Hello Felix,

Thank you for your answer and your explanation, I was a little bit confused
about this; I will check my Kernel configuration and rebuild with these
options, to avoid this messages.

It would be great if it could show a warning if this  options are unset (to
let us know)

Since you came across this, I suggest you file a bug and request that this 
feature is implemented in the ebuild so that the maintainer(s) pick it up at 
the next update.
