Comment 5 for bug 356049

As far as I know, having USB devices not resume isn't a major issue unless the device in question is a mounted USB disk, but you didn't mention that this was the case? Also, a device not resuming could simply mean the device was attached at suspend time, and was unplugged prior to resume.

I don't think the log message alone is anything to worry about unless it corresponds to a problem using your hardware after resume.
