The latter is This will likely fix my T43 to power down USB during STR. THANKS!! Now, I just need to check if the ACPI BIOS is smart enough to not do it when they are configured as wake devices [in the BIOS]. Although I do wonder WTF we don't do that on our USB UHCI/EHCI kernel drivers, that ACPI needs to step in to fix it. If it is not a wake device, why are we leaving it powered up? It is bad enough we don't have any sort of proper USB power control, but to leave the entire USB subsystem powered up without reason?! Vista not only powers down the USB HCIs and ports on STR, it also powers down ports when you "safely remove the USB device", and seems to leave the port powered down until you insert a device (or remove the device already in there, whatever). -- "One disk to rule them all, One disk to find them.
