[Bug 34066] Re: usb mouse dead on resume

[Mikko Saarinen]

This problem can be circumvented.

Modify the /etc/default/acpi-default file and put the usb modules to the
MODULES section and they are stopped on hibernate and restarted again
when you resume. No need to plug the mouse out anymore =)

To find out the necessary modules run the command "lsmod | grep usb".
On my machine it prints:

usbhid                 40992  0
usbcore               137700  4 ohci_hcd,ehci_hcd,usbhid

and my MODULES section from acpi-default looks like this:
# Add modules to this list to have them removed before suspend and reloaded
# on resume. An example would be MODULES="em8300 yenta_socket"
#
# Note that network cards and USB controllers will automatically be unloaded
# unless they're listed in MODULES_WHITELIST
MODULES="usbhid ehci_hcd ohci_hcd"

Hope that this will help others suffering from this same bug.

I read this from bug #46181. It is strange indeed that the comment above
says that USB controllers will automatically be unloaded if they are not
listed in MODULES_WHITELIST. Why do we still need to explicitly mention
them in this list?

Cheers,
Mikko
