Comment 10 for bug 150783

Hi Paulo,

Thanks for all that research and feedback. Just to provide some additional information, USB_SUSPEND is enabled by default in the Ubuntu Hardy Kernel:

ogasawara@yoji:~/ubuntu-hardy/debian/config$ grep -rn "USB_SUSPEND" *

amd64/config:2875:CONFIG_USB_SUSPEND=y

i386/config.386:1995:CONFIG_USB_SUSPEND=y

i386/config.server:1997:CONFIG_USB_SUSPEND=y

i386/config.virtual:490:# CONFIG_USB_SUSPEND is not set

i386/config.generic:1991:CONFIG_USB_SUSPEND=y

ia64/config:2349:CONFIG_USB_SUSPEND=y

lpia/config:2657:CONFIG_USB_SUSPEND=y

powerpc/config:2521:CONFIG_USB_SUSPEND=y

I'll also provide a link to the document you reference in case others don't know where to find it:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/usb/power-management.txt;h=b2fc4d4a99177be7bd48dce560d1f28417c60aa9;hb=HEAD

The solution you've found appears to have resolved the issue. From what was mentioned in the kernel doc, it's unlikely that the power/level attribute will be set to default to "auto" because of the issues it raises so I'll be closing this report. Thanks.
