I'm a relatively new user of sigrok/PulseView and ran into an issue trying
to use an FT232H on an Adafruit breakout board. When scanning for FDTI
devices (see output below) it gives the following error (which seems to be
similar to this bug report: https://sigrok.org/bugzilla/show_bug.cgi?id=1316).
The key error seems to be "Failed to get the FTDI strings", while the lsusb
output seems to indicate a problem listing certain descriptors such as
iManufacturer, iProduct etc.
Any guidance on how to fix this would be appreciated.
I can successfully connect to and pull data from a Rigol scope.
