[Nut-upsuser] nutdrv_qx hangs after send: QS

[Richard Flint]

Hi,

I have to admit this sounds like it could screw up the system if not done
right - particularly because the solaris packaging system is unlikely to
allow me to remove the libusb package if many things are dependent on it.

Are there any other options - e.g. doing something with the libusb that
ships with solaris - are we sure it doesn't support timeouts?

I think I found some code relating to it here:
https://java.net/projects/solaris-userland/sources/gate/show/components/libusb/wrapper/src

Regards,
Richard
