Hello, I'm afraid I can't even work out how to replace -usbdevice braille (or -usbdevice serial, all questions below apply, except making chardev default to braille):
... -usbdevice braille -usbdevice braille: '-usbdevice' is deprecated, please use '-device usb-...' instead but -device usb-serial is not actually documented in the manual page (same for usb-keyboard, usb-tablet, etc. for instance I can't find in the manpage anything about replacement for -usbdevice host:nnnn:nnnn) ... -device usb-braille -device usb-braille: No 'usb-bus' bus found for device 'usb-braille' ... -device usb-bus -device usb-braille -device usb-bus: 'usb-bus' is not a valid device model name So the error message above should suggest -usb. But then ... -usb -device usb-braille -device usb-braille: Property chardev is required that used to be a default, could we keep it a default when using -device? Hardly anybody would want to use usb-braille with something else than chardev braille. ... -usb -device usb-braille,chardev=braille -device usb-serial,chardev=braille: Property 'usb-serial.chardev' can't find value 'braille' Uh? It seems there is a parsing issue here? So I'm afraid a lot is still missing here. Samuel
