DFI P5BV3+ (VIA MVP3) and USB problems
Hi,
I cant use usb ports on the P5bv3+
I installed in win 98 correctly all via drivers (4in1 ver 4.35 and usb driver 1.10), upgraded to last bios (january 2000) and used an usb bracket from an asus motherboard. I activated USB controller in bios and is recognized in windows
The bracket has the same pin position of the DFI, according to both manuals, and is correctly connected (only 7 pins, impossible to invert as mistake)
I have tried 2 mp3 readers, 1 usb flash key and an usb steering wheel:
none of the items received any power from the port, and none as been recognized as "something just connected" in windows.
Do you have any idea about how to fix it?
And no, the solution is not using a separate pci usb card, i need the slots for other things.

RE: DFI P5BV3+ (VIA MVP3) and USB problems
Check the pinout of the on board port in the motherboard manual. I know that an Asus P5A-B has the onboard wiring configuration different from what you usually find with those ports; and you have to pull the wires out of the plug and rearrange them. Also I have one of those boards complete with manual. Just checked the manual. It takes a nine pin port not 7; unless yours is a different rev. with a different USB port.

Are you getting +5V on the designated power pins?
Thanks.
Thanks.

Well, the pinout on the manual says yes, but my devices are not receiving any power (mp3 usually turn on when connected but here it doesn't, same for the steering wheel). Anyway I don't have a tester for checking directly on the motherboard.KachiWachi wrote:Are you getting +5V on the designated power pins?

Not Connected. That might be your problem if the DFI requires the extra ground and your port hasn't got it.

Ground provides a zero reference for other power pins (among other things), +5V for instance is just a differential from ground.
That's why some use +5V as ground and +12V as power when connecting fans to get them to spin slower (less noise etc), that way you'd get a +7V diff.
As to the extra NC pin in the connector, the scanned manual Jim supplied states it's used as a key for the connector to make sure the it's not connected in reverse. The purpose of this is to make sure PWR and GND pins are not reversed, which can lead to all sorts of trouble like frying the device connected to the USB port etc.
Hope this sheds some light on the matter.

Thanks for the info.
Anyway it seems very hard to mod the bracket that im actually using, because no sort of wire starts from the nc pin that could be connected to another ground.
I have to search for a completely new bracket on ebay, and does not seems easy to find the right one, seems that the asus pin configuration has become a sort of "de facto" standard.

I have lots of them. Foresight. Bought a bag of thiry of them years ago. You want a nine pin one, no prob. Send me your address and I'll send you one for the cost of shipping.

Get yourself a DVM and check for the presence of +5V.
If you don't have this, no amount of cabling "fixes" will help you.
Thanks.
