Hi Samantha, 

Yes, that is exactly what happens.  

Fresh boot:

adam@adam-thinkpad:~$ sudo lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 04f2:b604 Chicony Electronics Co., Ltd 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Suspend, then wake:

adam@adam-thinkpad:~$ sudo lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 04f2:b604 Chicony Electronics Co., Ltd 
Bus 003 Device 004: ID 8087:0025 Intel Corp. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


8087:0025 suddenly appears after wake.  Wifi works the entire time, however.

This message that my bluetooth adapter being powered off also appears in my
bluetooth devices in KDE after waking from suspend (it is not there on fresh
boot).
