I think I would favour the first option.
BTW: Is it quite clear yet that this issue is actually usb device dependent rather than, for instance, host controller dependent? It just struck me that, according to your log message posted earlier, you are using ohci-hcd, whereas I'm using uhci-hcd and haven't come across this problem. This is on 2.6.21.5 with usb_suspend enabled connecting either the Handytech Braille Star or the old Modular 40 using a Prolific usb-serial converter. Just a thought that had crossed my mind, possibly all rubbish. Regards, Elias _______________________________________________ This message was sent via the BRLTTY mailing list.
