DragonFlyBSD

I've just ugraded to DragonFly 2.10. I have an HP Color LaserJet printer and a
APC XS 900 UPS, both connected to my server as USB devices. With DragonFly 2.8,
I had to boot the computer, then to connect the printer to the server for it to
be recognized. Otherwise the USB port was absent from the device list and the
system could'nt reach the printer at all.

2.10 corrected this problem, but in return, if both devices are connected to the
server, the UPS USB device disapears. The batterie is working but apcupsd is not
loaded. If I boot with the printer disconnected, and reconnected after the
complet boot process, everything's back to normal.
