My motherboard (Via KT400 chipset) has 6 built-in USB 2.0 ports, provided by
the Via 8235 southbridge chip. They've been OK, but Via USB isn't the best,
and I thought I'd try to do better.
I put in a Syba PCI card with 5 USB 2.0 ports (4 external, 1 internal) -
based on NEC chip - without disabling my motherboard ports! That made 11
ports in all.
Things seemed to be working ok ... but I had problems when I tried to use a
Seagate 200GB hard drive, installed inside an self-powered Adaptec USB 2.0
drive enclosure. I finally unplugged the Syba card, connected it to one of
the motherboard ports (via a 4-port external hub), and then the drive worked
all right.
What was the likely cause of the problem? Too many USB controllers / hubs /
ports going all at once? I didn't examine Device Manager too closely, but I
didn't see any "yellow bombs" showing any resource conflicts.
Funny thing ... I hooked up another drive (Seagate 120G drive inside an
older USB 2.0 drive enclosure), and it worked ok, even with the Syba card
installed and the motherboard ports still enabled.
