Andygraph:

You have to use a self-powered USB hub for these cameras to work correctly. Are you using it without the plug? This could be the reason you are having so many problems.

Like Bryan said -

You need a hub, that plugs into the wall. otherwise the cameras will not get enough current to load, and power up properly.

Hi Bryan,
nope, i have use the power plug to hubs but i have the same problem
so is not the power plug.
(sure, when i will take other cameras i will need use power plug)

-the real problem happen when plug the hubs to pc first of PC reboot-
if the hubs are plug first of PC reboot, arena don't start
if the hubs are unplug to pc first of reboot and then plug the hubs to PC
arena work fine, and i see all cameras.

If this is only a 5V, 1 amp hub, when using the AC adapter, then my guess is that they are not gettting enough current.

This hubs work well with 6 cameras without power plug (AC adapter), but D-LINK hubs no.
So why when plug to my hubs to pc after reboot all work well ??

I believe the problem go out when the PC make the reboot and check the periferical USB.. maybe the USB drive ?
