 I have seen a similar issue on my x61s Thinkpad while following the 8.0x 
 releases. The behaviour has changed throughout the releases.
 
 On my latest test (on FreeBSD 8.0-PRERELEASE #2: i386), I found this 
 issue only occurs if I suspend the system while no usb modules are 
 loaded. On a resume, if one then loads the usb modules (such as umass 
 ehci uhci), usb does not work.
 
 My current workaround is to ensure I load the modules I need before the 
 first suspend. A resume in this case does keep the usb ports 'active'.
 
 I'll report back if i notice any change in 8.0-Release.
