I noted errors during boot and resume which relate to the usb bus on
which the IR receiver is connected. Could these be related to my
unability to use remote wakeup with th remote?

There's another internal device on this bus, a Bluetooth receiver
managed by hci_usb. I guess the errors relate to this one rather than
to the IR receiver as the error reffers to HCI.
