Possibly this error is caused by your initrd. It should load ehci-hcd before uhci-hcd, not after. However if it only appears once then the error is harmless; you can ignore it. There's no way to tell exactly what went wrong just from a single error message. We have to see the entire boot-up system log. > If I just restart the machine instead of shutdown, I see one more usb error: > usb 5-1.2: device descriptor read/64, error -32 > > which would appear like some reset/close operation wasn't done in the restart. Again, if the message appears only once then you can ignore it. Restart does re-initialize all USB devices. > Is there some way to debug and isolate these problems further?

But if you want anybody to help solve the swsusp problem then you have to post a dmesg log showing what goes wrong when you try to do it.
