Re: [Linux-gpib-general] Problem with ibfind / ibask to get the minor number of controller

[dave p. <dpe...@gm...>]

Hi,
ibask on IbaBNA is only supported for device descriptors, not board
descriptors. This is a bit annoying but could be fixed. Why do you
need to determine the minor from the board descriptor ?
