and here's [1] the other device I own, with which I have the same bug. Actually they seem to be similar
hardware, same idVendor... the first one had 2 inputs for playstation
joypads, this only one which explains I think some of the other
differences (see output of "diff singular_adaptor dual_adaptor" at [2])

any ideas on this?

cheers
