Re: [H] USB Problem

Steve,
From your share, I get the feeling that you believed that plugging in a 
new PCIe card to your computer would solve your
trouble. I think you need to sit down an re-analyze your problem. You 
may have introduced new troubles (problems).
Did the new card install properly w/o errors?
Have your admin'd your devices to the new card?
Do your devices all work as expected?
So many questions. Yes, your PSU may not be'upto snuff.' Thatis just 
some more dollars, unfortunately.
Please keep us up to date on this. Data on USB is few and far between. 
Around my home USB is 'magic.'
Best,
Duncan

Yesterday, I popped a PCI-E USB 3.0 board (with external power), into 
the system.  Initially I did have the sound cut out in one game (went 
out for whole system), but since then, everything has worked fine, 
system-wise and in games.  The one oddity was that the MB was having 
fits (would not power up) with everything plugged in when the power 
was first turned on.  After standby power came up, I was able to plug 
everything in with no problem.  This seems to be +5VSB, so maybe it's 
time for a better power supply.

Theoretically you can have 256 devices. Realistically it's tough even 
on a
linux machine with quality drivers to go to 25+.  I fear where you

on windows without issue.

Troubleshooting you can do:  Get things as close to the root hub as
possible, use powered USB hubs and move around the device giving you
problems to see if a different USB root hub or path works better.  If
needed, buy a new USB card and see if that works for it.

Not many people get this many devices on a system.

Thanks for the reply.  I'll let everyone know how it goes.  None of

I'd do just what your thinking. Plug the card directly into a USB 
port,
skip the hub.
Hubs can be cheesy, quality-wise. Tripplite makes some great powered
hubs.

Still working out the bugs on the new build.

I *think* I have too many USB devices.

System is an Asus Maximus VII Hero, i7-4770k, 16GB memory, not
overclocked, Ancient 6850 video card.  Antech 650 watt supply.

Now for USB I have:  Video camera, 2 external drives, printer, 
scanner,
mouse, keyboard, two midi keyboards and the problem indication:  
Alva
Nanoface sound card.

When I had everything plugged in (printer, scanner & midi 
keyboards were
on an external hub), the sound would start out okay, then begin to
crackle, finally get so bad you couldn't stand it. Tried plugging
nanoface into just about every USB hole with the same result. The
nanoface expects USB 2.0.  Tried powering the hub, but that 
didn't help.

If I unplugged one of the midi keyboards, things were okay for 
most of
the time.  Every once in a while (days apart), I'd get the crackling
again, in the same way.  Tried a different hub, no joy.

I checked with the IT department at work, they said they'd had this
happen once, too many USB devices, but don't know if it every got 
solved
(it was at another division).

So I'm looking for some ideas on how to make this bullet proof. 
Right
now the performance is acceptable, on the infrequent times when it's
crackling, I only need unplug the nanoface and replug it and I'm 
good
for a while.

Right now I have a PCI-E USB 3.0 card sitting here.  It takes power
directly from the system PS.  I was planning on isolating the 
nanoface
with this card.  If the problem is power, this has it's own 
power.  If
it's bandwidth, then this card doesn't share bandwidth with any 
other
USB port.

Ideals?

Thanks....Steve
