Re: [DIGImend-users] Issues with DKMS deb package upon Ubuntu upgrade

[Caleb L. <ca...@te...>]

Hopefully I'm not spamming the mailing list, but another thing I've just
found:

On the original desktop that it was working just fine on, is now no longer
working. I'm certain it's plugged in (I can see it in lsusb), but not see
it in xinput.

I wonder if it's an issue of: it works when installed, but when any updates
are done (such as installing a newer kernel), that it stops working. Or if
there's just some underlying unpredictable bug in general.

Nonetheless, I downloaded the source on the other computer (the clean
Ubuntu 16.04 install, not upgraded from 15.10), and manually compiled, and
it's working fine now on there, again.
