I made this change and then ran BRLTTY, which worked after a few seconds. Killing and restarting BRLTTY, with the change still in effect, also worked. The following message appeared on the console and in syslog: Jun 15 13:14:49 jpc kernel: usb 2-1: reset full speed USB device using ohci_hcd and address 2 _______________________________________________ This message was sent via the BRLTTY mailing list.
