[BRLTTY] strange issue with mantis q40 and brltty

[Roberto Burceni]

Hello Dave,

Thank you for your anser.

Yes I'm trying to connect Humanware Mantis Q40 to debian trixie 
virtualized via utm on an Imac Apple Silicon.

When I list usb devices with lsusb the braille display seeme to be 
correctly detected her is the lsusb line

Bus 003 Device 002: ID 1c71:c111 Humanware Inc APH Mantis Q40

Attached to this mail I put the log that you required. At this moment I 
would like to work in usb mode.

As I said in the last e-mail the keyboard of Mantis works correctly.


Thank you
