I don't know what's going on with that frontend number. In fact, I don't know anything about DVB in general... but I am familiar with EHCI. It's not obvious what could be causing this, so let's start out easy. Try collecting two usbmon traces (instructions are in Documentation/usb/usbmon.txt), showing what happens with and without the reversion. Maybe some difference will stick out.
