Apparently, according to Stephen Booth, the developer of Decibel, it's an Apple related issue that should be fixed in the upcoming OS 10.7 ("Lion"). Let's hope that's the case. Using a USB hub fixes the issue for me (I am able to use hog mode without pops in Decibel though a USB hub) but could possibly degrade the sound, although I can't be sure whether that's the case or not.
