Please jump back in to this thread as i'm interested in your results thus far.
I am currently experiencing problems with my USB hubs with what i believe is overload. I current have them connected to 5v cigarette adapters (taken from cell phone chargers). I assumed it would be regulated considering these adapters must do the same for cell phones no?
Some help is appreciated.
There are still somethings i'm ignorant to; maybe a power supply as Stealth mentions in this thread is the way to go.
I do have an extra M2-ATX ps lying around. However, if what you say is true, do the 5v railings on the PS provide at least 2 amps?
echoing on what's been discussed here, i should use the ground of the power supply for my hub's and usb dvd player, yes?
I was considering going with Stealth's suggestion of grounding all devices directly to chassis, but there is a mixed feedback on this.
What do you think Mezz?
It all depends where the power is coming from. If you source the +5v for the hub from the M2 then you are much less likely to have any ground loop problems by using the M2 ground since it's likely the M2 ground is somewhat separated from the chassis ground. Using a chassis ground could introduce a ground loop and might provide for noisy power.
This all however theoretical. You might not have any problems in practice, so try what is most convenient and work from there.

@Maheriano thank you.
@Mezz implied the USB hubs may best be rated at 3amps for proper working conditions. Would 8amps introduce a new set of problems? OR are the hubs able to work with more amps but not less (such as <3amps)?
