[DIGImend-devel] tinkering with HUION tablet and the hidrd-convert tool to generate a HID report.

[Vince H. <Vi...@Pl...>]

the info file gives example of converting the hex input into xml
I get  invalid output format.
the output from your dump program is:
$  cat HID-descriptor2.native

$ cat HID-descriptor2.native | hidrd-convert -i hex -o spec
produces

what appears to be correct

but attempt to use -o xml generates error

appears the built in help says no xml output available while the
info output example shows using -o xml

Did I built it wrong?
