There is a motherboard manual here. JUSBV1 and JUSBV2 are 1x3 pin headers with a jumper plug on each. The header controls how the USB ports are powered. JUSBV1 controls the power choice for the rear (I/O area) two USB jacks. JUSBV2 is for the 2x5 USB headers, which would normally be cabled to a front panel USB if one was present. I've seen a couple different pictures of your motherboard, one with USB 2x5 headers installed, and another where there are no USB 2x5 headers installed. So I can't be sure that is what is wired to your front panel. You say you have a USB card, so some of those have one or two interfaces suitable for connecting to front panel USB as well. http://www.biostar-usa.com/upload/Manual/NCG0624C_B.exe (self-extracting RAR) There are two choices for JUSBV1/JUSBV2. They can be set to +5V or +5VSB. The latter choice would be useful for a USB keyboard, where you wanted the "wake up" function to work from the keyboard. If you're not waking the computer from a particular USB interface, then the +5V choice might be better for operation. On my current computer, all the USB ports run from +5V. +5V is a stronger power supply rail. Your Biostar board does appear to have taken precautions for the USB interfaces (like my Nforce2 board did). There is an electrolytic cap next to the USB ports, to filter the power fed to the USB interface. That is supposed to reduce the impact on system power, when a USB device is plugged in. So it probably isn't a problem like that. I'm suggesting +5V as a power source, more as a test case, than as a sure-fire cure. I doubt it is the USB Mass Storage class driver that is screwing up. What are the odds of that happening ? Especially when the rear port works OK with your Kingston 128MB. Do you see anything in Event Viewer, in terms of any error message logged during the jam-up ? Have you ever got a blue screen from it, with an error number or message ? Paul

"Legacy USB Support Use this item to enable or disable the support to emulate legacy I/O devices such as mouse, keyboard,... etc. Or you may select [Auto] so that the system will start to auto-detect; if there is no USB device connected, �Auto� option will disable the legacy USB support." There is another description here. USB Legacy Support http://www.techarp.com/showFreeBOG.aspx?lang=0&bogno=342 The one thing that stands out in your description so far, is that the back port works, and the front one doesn't. You'd think the USB Legacy setting would apply equally to all ports, so if some port works, then that probably isn't the problem. (The USB Legacy setting only applies to the motherboard USB ports. If you're using a PCI USB card as well, the legacy setting doesn't apply to it. As well, the BIOS would not be using the USB PCI card during system startup. I don't think you can plug a USB keyboard into a USB PCI card, and make BIOS setup screen changes with it.) Are you actually using a PCI USB card ? If so, please clarify which port is working in your tests. If the Kingston 128MB flash works when plugged into a PCI USB, then that is different silicon than if you're using ports wired to your Southbridge. The motherboard has a two jack stack on the back, in the I/O plate area. The 2x5 motherboards headers (if present), could be wired to a front panel connector. If you actually have a PCI USB card, they can have rear ports (in the PCI area), or on some of them, there is a connector intended for front panel wiring. Paul
From: L.S. on 5 Nov 2009 17:25 Found it after running test. Dumb me. I have a USB scanner plugged into pci usb card and that was causing conflict. I pulled tower away from wall and then noticed scanner was plugged into card. My last scanner was not a usb so wasn't thinking and it was plugged in right below where my Lan card is so didn't notice cable. Once I unplugged scanner, inserted drive in front, it worked fine. Have tested all 3 drives and they all work. Not sure why this is working because all I've done is replug scanner into the other port on the pci card, plugged drive's' in front slot and they all work fine. Why would plugging scanner into other slot on card make a difference? If you want to beat me about the head and shoulders, go ahead.

Cards with NEC brand chips, have been known to blow out ports on a regular basis. But I'm not aware of any side effects from that, other than the port no longer works on the USB PCI card. There is one other device with known issues. That is the Intel ICH5 Southbridge chip. The ports on that can blow, and a lot of the time it seems to be ESD (static discharge) related. While it is claimed ICH4 has a problem like that too, I've never run into anyone having a problem with ICH4. But I've probably conversed with at least 20 people that have lost motherboards due to ICH5. And I also happen to own a board with ICH5, and I'm extra careful to not use the USB ports on it :-) This is what a failed ICH5 looks like. A little burn mark, over where the chip gets power for the USB ports. Since the chip typically does not have a heatsink on top of it, it allows the unlucky user to look at it. http://onfinite.com/libraries/179057/2ea.jpg Paul |
