so you put the m2atx the the ''c'' mode....
mine was at that mode before(i try some other modes too)...and when the ignition was at ''on'' it was ok..but when i put the ignition at start...the pc restarted,....
now i am in the recomended mode of the m2atx..and i dont have this problem...but the pc shut down completly after 5 sec

The next batch of p5-uSB devices are shipping to us on October 9th. Depending on how long customs takes, we hope to ship these a week or two later around October 16th.
P5USBs are back in stock and ready to ship now ;-).
As you know the P5USB includes a reverse polarity protection diode to prevent damage to the P5USB in the event polarity to the input wires gets reversed. As noted by Bugbyte in his review, this feature works well (he initially accidentally mis-wired his P5USB and it was not damaged).
HOWEVER, if the P5USB in connected to a USB device, which is connected to a computer, which is grounded to the car’s chassis, THERE IS A SHORT CIRCUIT PATH WHICH WILL ALLOW THE BATTERY TO DAMAGE THE P5USB. Here is a drawing of the problem.
The top drawing shows the correct connection of the P5USB and the protection diode. If the battery wires are reversed, the diode protects the P5USB.
However, the bottom drawing shows how a reversed battery connection will short through the “ground” wires of a connected USB device that is also connected to a computer that is grounded to the car chassis. Once the P5USB is connected to a USB device & PC, reversing the polarity of the battery will damage the unit.
There is no way to protect against the short circuit scenario in the bottom drawing. This illustrates the need for a fuse in line with the P5USB so that if the polarity of the wiring is reversed the P5USB is not damaged. It also illustrates the need for installing the P5USB before connecting it to USB devices.
lol, congratulations sonic you just made it to the top of my list if I need a device blown up, and I don't mean that in a bad way. Finding little use case scenarios like this is really hard. I talked to Stephen about the PM and he'll get back to you.
Hi guys! I just received my USB hub here in singapore. I need HELP!
Firstly, my PC (currently on Viliv S5) crashes(blue screen!) when i try to plug in my creative external USB sound card to the hub, or when i leave my usb cable connected and restart my S5 it refuses to start up.......
What went wrong? The sound card works well with direct connect to the S5. Note- i only have the soundcard connected to the hub.
the other USB devices works fine - USB 3G modem, GPS works fine.
Second is 500mA enough to power a external DVD drive? with a single cable connection?
My ride is Honda Civic FD
Ugh my last post about this got lost... but creative sound devices generally need to be plugged directly into the computer else they exhibit the behaviors you describe.
More than likely you will need 2 cables to power that dvd drive reliably. Most of them come with 2 cables for this reason.
