You mean your laptop has an EHCI controller but no USB ports? That's odd... Anyway, here are instructions for you or anyone else who can do the test. (I forgot to include them in the original message.) Running the test involves two steps. The first step is to check that an unpatched system supports Wake-on-USB. This means enabling it in the BIOS and/or in ACPI (whatever that might entail; I have no idea what's needed) and actually trying it out. Either plugging or unplugging a USB device while the system is in STD should wake the machine up. The second step is to see whether Wake-on-USB continues to work after applying the patch mentioned previously. That's the real question. It may turn out that _nobody_ has Wake-on-USB working at all... in which case we'd have a different problem to solve. Alan Stern
