[vbox-dev] Oracle VM VirtualBox is not supporting The Tieman braille voyager Braille display

[Jean-Philippe MENGUAL]

Hi,

Only to try understanding better your case: can you confirm that your host is
Windows XP? Then, what's your guest OS? What screen reader do you use on the
guest? Does your problem happen when you try using your braille display in the
guest or only in the GUI interface of VirtualBox on the host?

I think some log of VBoxManage list usbhost could be useful. What methods have
you tried to connect the display: filters? usbattach? I think 1st, it's useful
to understand what happens on the guest, then developpers will try to see
how VBox emulates your device.

Thanks for your details.

Regards,


JPM
