Ah, success!
I removed ehci-hcd. Immediately after I did that the OHCI driver found the
external HD and then proceeded to detect drive sdc. I then modprobed
ehci-hcd. This caused the entire bus to be rescanned. This time, all devices
were detected and enabled, including the external HD.
At the very least, I can put this module unload/load into a startup script to
make USB behave. Is there a better short-term solution than this?
I have attached a partial dmesg output. It contains everything after I did
the "modprobe -r" and then the "modprobe".
