Yes, that's correct. >I've tried connecting via USB, and that also does not seem to work; It should. I've tested that with a Humanware BrailleOne, which is effectively the same device. >brltty starts via the udev rule, but I get no output. Perhaps you could capture additional information by logging with: -ldebug,brldrv,inpkts,outpkts >The following is logged repeatedly after connecting: Repeated logging would mean that the driver startup isn't succeeding. >Mar 04 14:21:02 p1 brltty[402]: USB configuration set error 16: Device or >resource busy This is usually not a problem. When it fails with busy as the reason then brltty detaches the device from the kernel's driver so that it can use it. >Mar 04 13:59:52 p1 brltty[384]: USB: endpoint descriptor not found: 84 This is the actual problem. Could you please post (or send to me directly) a copy of the file /sys/kernel/debug/usb/devices while your device is connected? -- I believe the Bible to be the very Word of God: http://Mielke.cc/bible/ Dave Mielke | 2213 Fox Crescent | WebHome: http://Mielke.cc/ EMail: [email protected] | Ottawa, Ontario | Twitter: @Dave_Mielke Phone: +1 613 726 0014 | Canada K2A 1H7 | _______________________________________________ This message was sent via the BRLTTY mailing list.
