Guess what, this issue indeed seems to be completely unrelated to USB. Something similar is going on for SD card access (see Bug #787246), and accessing LAN/WLAN has only an indirect influence.
Look at this: http://paste.ubuntu.com/656410/ Seems like the CPU entering sleep states or something similar is the culprit?
