Eventhoguh, when I run the mkinitrd > /boot/initrd-2.6.30.img 2.6.30, it says already exists. Of course it already exists. You couldn't boot without it. But you need to create a new version, one that will include the debugging code. Otherwise when you boot, the kernel will load the old driver from the old initrd file -- and the old driver doesn't have debugging enabled. Alternatively, you could rmmod usbcore after the system is running and then modprobe the new version. To do that, you will first have to unload ehci-hcd, uhci-hcd, and ohci-hcd (maybe some other drivers as well) and unmount /proc/bus/usb.
