The "sudo modprobe ehci_hcd" made no difference. When I tried to restart brltty I got the same result. I also just tried the latest brltty sources from head with the same result. If it would help, perhaps I could allow you to ssh into a machine that exhibits the problem. I'm normally not into opening ports but for abit of testing it should be OK.
