Unload all usb drivers before suspending please.
I hope this isn't a general rule? I can't keep up with the list, but I saw this message, and it looks like a disaster.
There are a lot of small-size desktop machines that depend on USB keyboards because they don't have PS/2 ports. In some cases the keyboard includes a PS/2 hub for a PS/2 mouse, but in some cases the keyboard doesn't even have that so the mouse is also USB. In all of these cases the connection to the CPU goes through a USB port.
How should the user restore their keyboard after resuming from suspend? A modprobe or insmod command? In the vast majority of these cases the input of a command would depend on having the USB keyboard already working.

Right now, yes that is the response if anyone has any problems with this, sorry.

Have the resume script re-load the drivers. A lot of people are already doing this.
