There's no way to fix the USB problem without knowing what goes wrong. Let's see how far you get before the system freezes on a kernel with CONFIG_USB_DEBUG enabled.
Am I missing something?
I've enabled CONFIG_USB_DEBUG but don't see any additional module parameter nor anything extra to toggle and I don't get more output than without it.
Depends what you mean by "output". The kernel generates more log messages, but they may not get sent to your console. You need to make sure the console's log level is set high enough to see debugging messages. For example:
echo 9 >/proc/sys/kernel/printk
or type Alt-SysRq-9.
I've been doing `dmesg -n 8` (9 is rejected as invalid) so it should send out everything. It looked like there was some more output during boot-up, but nothing during suspend, at least up to the freezing point.
