I've never had a problem with an MSI mainboard in the past and I have installed hundreds of them, its what I do. But after searching for hours and finally finding that the Front USB port is the cause of the system not powering up I was baffelled.

I use Auriga Midi Tower Cases mainly and this 2168B was no exception. I changed the Front USB connector and still have the same problem. There are only 8 pins for 2 USB channels at the front. There is no OC connector or wire here. Unless it is grounded right at the front of the case.

I will check this out and if anyone else has any bright ideas please post.

You just solved a problem that had me stumped! I had no front case USB and no USB from the rear USB adapter, only the two ream MB connhectors. The problem was the pin 10 wire on the front case connector. That also disabled the other on MB connector! One clip and I have six more USB ports. Sincere thanks. Why do they do that???????????????

Not all manufactures will follow the specs on USB to the letter. I have researched this intensly and have yet to find anyone that will mention it in the User Manuals of their products. My own issue with MSI not responding to email was resolved when I called about a different problem (video card HSF died). The Tech that I talked with apologized profusely, but was unable to give me a definitive reason why it was not mentioned in the users guide. There will be a addition to them in the near furture supposedly.

Anyways - Good luck and stay tuned. If I find out more information I wll be sure to post it. Also check out the CPU Forums for more good information.

Later.

Brad.

Hello guys,

working in a university, I recently bought for one of our departments 60 MSI mainboards (model i865PE Neo2-V). Now that we installed the PCs, we just discovered this USB problem... when you connect a USB 2.0 device on the front connector, the system (Win 2000) hangs and stops responding but it works fine on the rear connectors.

This is quite a big issue for us as USB mass storage flash disks are the main (I should say the only one) storage media we allow our students to use. Of course they also can use the 3"5 floppy disks but well.... :biggrin:

I'll try to unwire pin 10 tomorrow (it's currently wired to the shield end of the front connector cable) and if that works, I'll thank you gratefully tomorrow... and will probably damn MSI for a hundred years for not mentionning this in the "user manual" provided with the mainboard cause I'll have to open 60 cases thanks to this lack of information despite it seems to be a known issue... :angryfire:

Anyway thank you for the input, and stay tuned for the answer...

Regards

Actually, it's the case manufacturers fault rather than MSI (although, why the #10 pin isn't electrically isolated...). The case manufacturers are including this 9th wire to the #10 pin which is unneccessary with using the Intel USB spec. I kinow Gigabyte uses a different layout.

:biggrin:Hello guys,

as promised I come back here to give the results of my tests... and I have to say that you saved my day (even if I had to open back 60 secured cases).

So the solution was the right one, when I unplugged the "ground" end of the front USB connector cable from the USBOC pin, those connectors finally worked as expected with USB 2.0 compliant devices.

So thank you really much for this very usefull information !

And even if maybe it's not only MSI's fault, I still believe that more information on those connectors in the user's manual would be really usefull (who knows what USBOC means except a few people and who could imagine that pluggin on it a "ground" cable would make it unserviceable ??). And who ever saw a user's manual bundled with a case ?? it's pretty unusual :-P)

Hope that someone at MSI will read that and take it into consideration, not for me (because now I'm aware) but for the thousands other consumers that will feel a little bit "annoyed" with that issue. I don't think that adding one line about it in user's manuals would be so much expensive ;)

But I'm quite lucky myself... being able to understand and write english (even if I still have some progress to do :biggrin:) gave me the possibility to find the solution... but a lot of my french fellows can't do that... and there's no french forum here... How can they do ? They rely on user's manual ;)

Best regards,

Nicolas

so this OC lead to nul the ports when using both 2.0 USB port at same time.
PCI header came with a sticker covering second 2.0port for that reason
to pervent overload.

OC pin is idiot proofing when wired correctly so beware not to overload when cut wire
Originally printed in MBmanaul
BECAUSE the BLUETOOTH connector shares the USB inface with onboard USB pinheader. the USB port coverd by a sticker will not function when you attach a bluetooth module to this connector.

As you can see over there [KT4V-L MS-6712] USB 2.0 & Win2k pilots , I really pulled my hair off as this damn bug can't possibily be spot if the user manual is dumb about it !!!!

I didn't reinstall this box for a very long time and this goddamn bug is the only thing which got me on my knees ! :angryfire:

Great posting!? Wish I'd read this a couple of days ago - and saved myself a lot of hassle.

I've just bought a Neo2 Platinum board (MS-7028) designed for Intel processors and have the same problem.? If I connected a USB device to ANY of the ports connected to ANY header on the mb, the system would hang.? Occasionally I'd also get a Windows error message, "A USB device has malfunctioned and exceeded the power limits of its hub ports.? You should disconnect the device."? The four rear-facing USB connectors on the mb were unaffected.

My case is a Termaltake Tsunami and has two flat connector plugs on the two front-facing USB leads.? After reading this posting I checked and all 5 pins in both connectors are wired.? Both flat connectors have to plug into the same USB connector on the mb.? As it turns out, plug 1 on row 1 is OK because of the missing pin 9 but row 2 was the culprit because all 5 header pins were connected.? Disconnecting USBOC and taping the wire back has solved my problem.

MSI support (UK) blamed SP2 saying, "Windows XP service pack 2 has stricter (power) requirement than pack 1".? This clearly wasn't the cause of my problems.? I would suggest MSI revise the motherboard manual to mention this.

Thanks once again.

on my mobo, there is only 9 pins, and using the tsunami casing, The top panel USB are 2:
USB1
USB2

Since there is only 9 pins, the USB 1, the 5th does not connect  to the USBOC thing/there is no 5th pin. So I did not cut the wire for this one. Is it ok? For USB2, there are 5 pins, I just gvut the wire going to USBOC, the 5th wire. Tried 1.1 it works. I have trouble finding 2.0 devices now.

Assuming both your top panel USB cables are plugged in to the same USB header on the mb, this should work.? AFAICR, mine are plugged in to JUSB2 and I have the D-Bracket USB connector plugged in to JUSB1.? Mine both work and I did not disable USBOC on USB1.

I can't understand why 1.1 devices should work OK but you are having trouble with USB 2.0 devices.? Have you checked your BIOS settings?

I have the CMStacker and have the front USB 2.0 ports installed. I'm having problems with the rear devices (Saitek Gamers Keyboard and Razer Diamondback mouse). Would it help by following the instructions above? I don't really want to cut a wire to find that I didn't need to.

Thanks

Chris

I had gotten a reply from you in another message area and couldn't find a way to start a new thread.

I've been thru every message in this area at least 100 times. I understand that some have cases that
have usb ports on the front panel, and a extra wire was connected that needs to be cut. One person
left a message in the same situation I'm in. Our case don't have USB ports and we're just using the
D-Panel. We get the same problems everyone else has. That person who left the message didn't
get a reply. I did read one message where WinXP SP2 maybe the problem, before I reinstall winXP SP 1
I would like to see if I have other options to help correct the problem. When I plug my Scanner in to a usb
port on the rear, I get "unknown device". I connected 2 D-Panels in to jusb1 and jusb2 then try these
ports, the two ports on jusb1 don't even see the scanner, the ports on jusb2 i get the "unknown device".
I cleared the cmos and reset the bios, that didn't help, hell I ever upgraded the bios. Does anyone have
any other ideas on this problem? I would like to go to bed at reasonable hour.
Thanks everone

Is it just the scanner? Other USB devices, do they work?

Sometimes, but this probably not the case here, you have to install the scanner driver first, reboot, and then attach the scanner.

USB devices doesn't need mush more than a correct connection to the pins.

I don't think you were reply to mine, but I have been having the same usb problems. So happens I got in to this trying
to get my scanner going. I'm only using jusb1 for the d'panel. The usb ports say "unknowm device". I have cleared the
cmos. I removed all usb drivers and had the system renstall them. What I have now is the on-board usb disabled, and
installed a pci usb card and this found my scanner right off. With the pci card installed I turned the on-board usb and
the pci card still sees the scanner and the on-board usb still don't see the devices. If you or someone else can figure
something out, I'll love you for ever

You say you have a scanner. I do think I was answering your post. :undecided:

Nice you got things going. I don't think you would have needed the PCI-card to fix your problem. Letting Windows have its way, with its own drivers, should have sufficed. Which you did! :biggthumbsup:
