I have a Gyration Keyboard and Remote combo (GYAM1600CKUS, GYR3101US) that work off the same USB wireless transmitter. When I suspend the pc to S3, pressing a button on the keyboard will wakeup the pc, however, no buttons on the remote will wakeup the pc. Could this be a problem caused by two interfaces being on the same USB device? If not, any other suggestions? Thanks
I am using kernel 2.6.27 r8 (gentoo)

I used acpitool to set the wakeup on the USB port:
> acpitool -W 14 14. USB4 S3 enabled pci:0000:00:1a.1
I tried looking at the ACPI setting in /sys/devices/*/power/wakeup. You can see below that the usb device has 2 different inputs "./usb4/4-2/4-2:1.0" is for the keyboard and "./usb4/4-2/4-2:1.1/" for the remote.

Most of these are blank, but some of them are enabled:
./power/wakeup:enabled ./usb4/power/wakeup:enabled ./usb4/4-2/power/wakeup:enabled
Also to note, this remote is similar to the Fiire Chief remote which looks as if it does wakeup properly.
Thanks so much for any help given. And please let me know if any more information is needed. I am happy to help as much as I can.
