 I manage to keep the USB ports usable by building and loading all USB
 components as modules:
 
 /boot/loader.conf:
 
 usb_load="YES"
 ehci_load="YES"
 uhci_load="YES"
 umass_load="YES"
 ukbd_load="YES"
 ums_load="YES"
 uhid_load="YES"
 ucom_load="YES"
 umct_load="YES"
 uplcom_load="YES"
 
 ...and unloading uhci(4) in /etc/rc.suspend:
 
 kldunload uhci
 
 ...then reloading uhci(4) in /etc/rc.resume:
 
 kldload uhci
 
 Only uhci(4) should be unloaded/reloaded, as any other USB component
 being unloaded/reloaded seems to put a kink in things.
 
 As of a few hours testing, this is functional as a work-around.
