Start with the simple stuff, reconnect everything and check dmesg to see if everything is detected properly when reconnected.
I assume everything was working up until you installed the new Ubuntu version, so it could be a bug/issue in the new kernel, so maybe try downgrading the kernel and/or trying a back ported version if there is one. It could also be a cable issue, do you have a space to try?
