Resume from standby not working from USB event

Sat Sep 27 19:05:44 UTC 2008

Hi everybody

I'm really getting desperate here. I turned an old Sony Vaio SR11K  
into a digital frame for watching TV, Movies, listening to music etc.  
I could manage a lot of problems so far, but I can't get the laptop to  
wake up from an USB event, such as pressing the Power Button on my USB  
remote. I adapted the hibernate configuration to send the laptop only  
to S1 mode, since it USB0 only seems to support this state:
 > cat /proc/acpi/wakeup
Device	S-state	  Status   Sysfs node
PWRB	  S4	*enabled
USB0	  S1	 enabled   pci:0000:00:07.2
CRD0	  S3	 disabled  pci:0000:00:0c.0
MODE	  S3	 disabled  pci:0000:00:0a.0

As you can see here I also managed to enabled USB0 to wakeup from S1  
mode. I changed a line in /etc/hibernate/sysfs-ram.conf to
UseSysfsPowerState standby
and now it really goes to S1 mode. After executing sudo hibernate-ram  
the screen gets black and the machine turns of.
When I press now the Power button on the remote, the machine turns on  
(somewhat), the fan starts turning but there's only a blinking cursor  
on about the forth line. The vaio doesn't react to keyboard input nor  
remote buttons (also tried the (CTRL+) ALT-Fx) to switch the tty. The  
only way to proceed from here is to cold restart the laptop. So far so  
good, but now the really weird thing: The whole thing works, if I  
press any keyboard button, when the machine is in sleep state.
But since the whole laptop is integrated into a frame and the keyboard  
is not accessible pressing a button is not an option. The behavior is  
exactly the same if I simply write standby to the appropriate /proc/ 
acpi/ file.
So why doesn't the machine only doesn't wakeup when I try to activate  
from USB device (I also tried a mouse plugged to USB0: same thing).

If I would have to guess, there must be a difference between the USB0  
device and the keyboard (maybe a IRQ) which lets the machine wake up  
completely with one and let it stay in zombie mode with the other...

I'm grateful for any idea, I just run out of options...
