As the message above from emerge says, no way to update
sys-fs/udisks as CONFIG_USB_SUSPEND is not set. The problem is
where to find that option. Not in linux/.config, so where ?
i think it only shows up there if it is already set. AFAIK the
kernel options are defined in the various Kconfig files spread
throughout the source tree. in this case
drivers/usb/core/Kconfig
when searching for an option you can do
find /usr/src/linux/ -name Kconfig \
-exec grep USB_SUSPEND {} /dev/null \;
which gives you two hits:
/usr/src/linux/drivers/usb/core/Kconfig:config USB_SUSPEND
/usr/src/linux/drivers/usb/core/Kconfig: depends on USB_SUSPEND
and
grep -A 20 'config USB_SUSPEND' /usr/src/linux/drivers/usb/core/Kconfig
giving you description and help:
config USB_SUSPEND
bool USB runtime power management (autosuspend) and wakeup
depends on USB PM_RUNTIME
help
If you say Y here, you can use driver calls or the sysfs
power/control file to enable or disable autosuspend for
individual USB peripherals (see
Documentation/usb/power-management.txt for more details).
Also, USB remote wakeup signaling is supported, whereby some
USB devices (like keyboards and network adapters) can wake up
their parent hub. That wakeup cascades up the USB tree, and
could wake the system from states like suspend-to-RAM.
If you are unsure about this, say N here.
Cool tip for the future: Go to /usr/src/linux, type make menuconfig.
Then type / (slash). Then type SUSPEND and ENTER. It will show you
all the kernel options with SUSPEND on them.
or this, of course ;)
This is my preferred way of searching the config. Note that you can't
select USB runtime and power management (autosuspend) and wakeup, if
Power management and ACPI options - Run-time PM core functionality is
not set.
I forgot that some time ago, leading to some errors while unmounting USB
sticks with udisks (although most of udisks works without this option
set, it just can't power down USB devices after they are unmounted).
In particular, for USB_SUSPEND it says:
Symbol: USB_SUSPEND [=y]
Type : boolean
Prompt: USB runtime power management (autosuspend) and wakeup
Defined at drivers/usb/core/Kconfig:93
Depends on: USB_SUPPORT [=y] USB [=y] PM_RUNTIME [=y]
Location:
- Device Drivers
- USB support (USB_SUPPORT [=y])
- Support for Host-side USB (USB [=y])
So there, is in Device Drivers - USB support - Support for
Host-side USB.

That's extremely hardcore. Using / in menuconfig will not only give you the
menu where the option resides, but also state it's status (checked,
unchecked or module), it's dependencies and short description.
