If you're having problems with USB ports, read on...

i'm reading that alot of people on here are having problems with their front (or top) usb on their cases not working with their k7n2 boards. i have come across the correct solution to this problem in one of the posts (after having solved the problem on my own), however noone has posted the solution by itself on this forum so everyone can easily see it.
The trick is to make sure that pin 10 (at least on a K7n2 delta-L), the pin labeled USBOC (USB Open Connection), is wired to NOTHING. If the connector to your front usb ports is fused into one giant connector and it HAS a wire that will connect to this pin (labeled GND2 or Shield or something), CUT THAT WIRE. Pin 10 on JUSB2 (at least on a K7n2 delta-L) must be OPEN. If this pin IS connected to something (even if it is only GND), the motherboard will think something is connected to this usb port and you will get many unknown devices listed in your windows device manager and the rest of your usb ports may or may not work.
As a general rule of thumb, if a pin on a motherboard is labeled OC for "Open Connection" and you wire something to it, you're asking for trouble.
If you cannot understand this you should not be attempting to wire a motherboard in the first place.
Here is a picture to go along with this discussion. If you cannot see this picture, I am sorry for it has probably been removed from the place I posted it online as I cannot attach pictures physically to this post. If someone here has a way to permanently host this picture and post it to this thread permanently, that would be wonderful.
In summary: all usb ports/headers have only four pins associated with it (VCC, USB+, USB-, GND). If the connector (whether it's one big connector or individual sockets) to your front/top usb port has 5 sockets, don't connect the 5th socket to anything. That goes for any case/motherboard combination. This is what i'm talking about above. I have no idea why motherboard and case manufacturers have a 5th pin involved in any way on either the pin or socket side. It is not used for usb.
EDIT: I just noticed this has already been discussed in the trouble shooting guide in the above sticky post. oh well, now we have a pretty picture to go along with it (i hope).

:-D)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
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 ) 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

Will 800 MHZ Quicksilver USB port read a 2.0 USB Lacie Hard Drive?

Hello everyone
I have an 800 MHZ Quicksilver, and was wondering if it can read (adequately), either a USB 2.0, or Fire Wire conected Lacie external Hard Drive?
I'm going to install the 1.2 Upgrade Processor:
http://eshop.macsales.com/item/Seagate/ST3400620AS/
But I don't think this upgrade effects the speed of the USB Ports?
I also installed a Multiport Fire Wire PCI card, but through this card, I get latency problems in regard to audio. It's not as fast as the built-in Fire Wire Port.
Thanx
Mike

Hello Allan
Thanx for the tip
Do you have the same system that I have?
Is this your card:
http://www.sonnettech.com/product/allegro_usb2.html
If so, it seems to actually make up for (adjust or boost), the system's USB speed capability
And maybe I should pick up one of these too?

Can I attach USB drive to Airport Express USB port

I would like to attach a USB drive to my Apple airport Express USB port so that I can back up my data on my MBP and have my music stored on it for playing back over Apple TV.
Is there any issues to doing this? As an example, how would I see the drive?
thanks in advance.
Adam

Well, you can certainly attach a USB drive to the port on the AirPort Express.....but nothing will happen if you do this....since the USB port on the Express will only support a compatible printer and Keyspan remote control.
You will need an AirPort Extreme if you want to attach a shared hard drive to the USB port.

Problem --serial port reading one character at a time

Hi Friend,
I reading the serial port one character at a time , i specified it in the "serial bytes to read" option in serial port read examples.
The problem is ----------i can able to read the data.
but only the first character is reading again and again...and "reading string indicator" in the serial port example shows only the first character sent ..only for a single time.since i am reading continously ----aleast the first character should display as many times i running the program
(i am running the vi by run continous option..........)..
please help me ....how to read the character one by one.....
regards
rajasekar

Hi jason...
I can able to read the serial port by 1 byte or 2 byte or 4 byte as i can specify it in the serial port read bytes option..(in visa serial read)..
I need to acquire 4 bytes of data and pass it to the Math-script node..and save these 4bytes of data in array (1 row and 4 column)..
And split this array(just like array-indexing.vi) and processing it each each column separately....
or suggest some method to achieve my task.....please.
one more thing the math-script node is placed in a while loop.....in order to read sequence of bytes continously.......
regards

HT1349 playing music through usb port

hiw do i play ipod touch through a normal hifi with either usb or phono plugs when i connect to usb connection im told it is not compatable yet my origonal i pod works fin

The problem seemed to be with the 360. Had to unplug/replug the power source to the 360. Apparently the problem was with the 360 USB ports.

Playing 5thGen through USB Port / Xbox 360

My iPod is not recognized by anything other than a PC. I had an older iPod that I could plug into my Xbox 360 or a DVR cable box and I would get a "Do not disconnect" sign, and be able to play through these devices.
When i plug my new 5th gen ipod into either of these, there is no change to the screen. My xbox 360 does not recognize that I have a portable device plugged in. Again, this worked fine with my older ipod.
I have tried putting it into disc mode as well, but this doesn't change anything.
I also have downloaded the optional ipod support software for the xbox 360.
Is there something that I need to do to the ipod to get it to be recognized by a non-PC?
Thanks.

Solution to only TWO USB ports, please

I should have paid more attention when I bought my Mac. I didn't realize there were only TWO USB ports on board. My job requires me to be mobile, and on any given day, I could be using up to 10 USB ports. I know they make hubs, one of which I've tried, but it didn't work. Does anyone recommend a particular brand of hub that's RELIABLE and can handle both input and output?
I'm stunned that Apple would have just 2 USB ports. My old Dell had 4, and if I remember right, I could have specified even more when they were building it.
Diane

Yes, that's the ExpressCard/34 port (labeled in this linked image). The ExpressCard port also be used for media card readers, WAN (wireless broadband) cards, etc. Good for a USB expansion hub because it's a small form factor and won't take up one of the two existing USB ports.

IPhone 3G won't charge from USB port

Suddenly I am getting an error sound (no message though) on my computer when I plug my iPhone into its USB port and it no longer charges the battery. I don't have iTunes on this computer (not allowed/work computer) but I have been using the USB connection to recharge my phone until yesterday when it stopped working.
Here's what I've tried:
1. Tried 2 different cables - same result, no charge and an error tone.
2. Tried connecting to a USB hub, direct to several USB ports on computer, and via a USB port on the computer's keyboard - same result, error tone and no charging.
3. Tried various combinations of two cables and two AC wall adapters, all work fine to charge my phone.
4. Tried plugging my iPod into the USB port on the computer and Windows XP immediately identified it as a iPod and started charging it.
I have not tried plugging it into my home computer where I sync it since this started happening yet.
Is there something wrong with my phone?

I've had a computer "suddenly" refuse to charge an iPhone that it had previously charged reliably.
In my case it was because Vmware was active in the background managing a background Virtual Machine, and it grabbed the USB port on behalf of that background machine, which immediately gave the proper beep sounds, but since the virtual machine had no drivers, it didn't charge. (in fact the charge indicator went backward fairly quickly).
If you have to ask what Vmware is, this is probably not your problem, but there may be similar scenarios that could cause this with background tasks, or other logged in users running things that think they "own" the usb port.

USB port not functional at startup

This is 100% reproducible. I plug my 23" Apple Cinema monitor into my new 2.8GHz MacBook Pro. I use a display to DVI connector for the monitor and plug the USB from the monitor into one of the USB ports on the mac. I have a third party mouse and keyboard plugged into the back of the monitor in the build in USB hub. Each time the mac starts up, the keyboard and mouse are dead. I simply switch usb ports and they come back to life. For some reason they are not recognized at startup. Does this have something to do with the hub on the monitor being "slow usb"?

Is the hub in the monitor self powered (from the monitor's power supply) or does it get it's power from the MBP port? If it gets it's power from the MBP port, and the inrush current of trying to power up two devices at the same time exceeds 0.5 amps, the MBP will shut down the USB port.

USB Ports on my MacBook Pro are not working

My MacBook Pro (Original) USB ports recently stopped working. They come up in system profiler as being there, but when I connect a device, such as a flash drive, no leds turn on, and no power is given to it. I have tried resetting the SMC and PRAM, but all to no avail. Does anyone have any suggestions? Thank you in advance for your help

I had a nearly identical issue today with a new CTO MacBook Pro...specifically, the USB ports on this new unit were unresponsive to devices being plugged to their slots. We reset SMC to no avail, unplugged all other non-essential peripherals, and still no change.
We were specifically trying to boot a previously functioning Seagate hard drive with a fully intact install of Snow Leopard. Eventually the MBP detected the drive and read the contents. We selected the externally connected drive for startup (which S/L found without issue) in System Prefs. At boot, no progress further than Apple logo (without animated gears indicating some type of load process).
Moved to an identically equipped secondary Thunderbolt MBP which presented with exact same issue. To further verify this was an issue with the USB ports on a Thunderbolt model MBP, we attempted boot of the externally connected drive to an iMac and then a MacMini. Both of these units booted the drive without issue. The Thunderbolt MBPs can see the drive, read the contents, but can't boot them.
Disk Utility verified and ran repair on the external drive and reported zero problems.
Both MBPs are being returned to Apple. Too much to risk for only having two USB ports.

USB ports - half functional??

I'm using MS-7057 Intel 845-GV series.. I have 4 USB ports at the back (onboard); 2 at the front. Whenever i connect anything to the 2 at front, the whole pc reboots after saying "The USB device you connected exceeded power limit on the hub" or sometrhing. But thats ok, i barely use them, no issues.
For my rear USB ports, If i connect a device, it'll light up, indicating that it is indeed receiving eough power.. right?? But Device Manager fails to recognize that anything has been connected. I tried re-installing Windows, Updated BIOS, removed the battery and tried resetting the bios, every possible thing that i knew could possibly help me. However, unsuccessful. What to do??

Okay, first, make a signature. Look at mine to get an idea of what we would like to know. If you are having problems with USB ports, read this topic. Also, here is what I've written before concerning USB issues:
Quote from: Frankeputer
Check to see if there is a wire running from your Front USB ports to the #10 slot of your USB block which connects to the motherboard header.
USB connector block layout which corresponds to the pin layout on boards with the Intel spec for USB. Do not cut the pin on the MOBO. You are removing/cutting the wire to the connector block from the case.
2 4 6 8 10(this wire, #10, not needed)
1 3 5 7 9(filled/key)
If you find a wire leading to the #10 spot on the block, remove that wire. My block has tabs so that you can pull the wire out, or you could snip/cut the wire leading to that position--if you cut the wire, be careful to cut the correct one and cut it in such a way that it may be repaired if you make a mistake. Make sure you wrap the wire, the exposed end/s, you remove/cut with electrical tape so as not to accidentally cause a short. I actually folded the wire back and wrapped it.
2 posts to read--Here and Here.
This seems to be a common issue involving many different case manufacturers. I don't know how it applies to other MOBO manufacturers, but in these forums it is not limited to a specific MSI model or supported chipset(Intel or AMD).

K8MM3-V USB port pins

Installed m/b K8MM3-v and all worked ok. Any one know how I can wire up the fron USB ports as my case has single wires and not a plug on. It has 8 wires with single black sockets and written is - I managed with the old one but don't want to make a mistake with this and do I need the 9 pin to be wired to anything.
1.vcc red
2.vcc red
1.data+ green
2.data+ green
1.data- white
2.data- white
1.gnd black
2.gnd black
The JUSB1 has 9 pins.
Thanks for help

If you are having problems with USB ports, read this topic.
That gives you a good idea of whaty not to hook up. Otherwise the rest of the pinout should be in your manual.

I keep getting 'USB port is drawing too much power error'

I have an old 2010 13" MacBook Pro. Just tonight, it started giving me a 'USB port is drawing too much power' error. The only thing I had plugged in to my MacBook was my iPhone cable (without the phone) and an Intuos tablet I recently bought. At first I thought it was the tablet, because the tablet started acting wonky after that error message (it worked just fine earlier in the day).
After restarting, the tablet works with no problem so I thought the problem must be the iPhone cable. The thing is, I read in some other forum that a cable not plugged to the iPhone shouldn't draw power, and they said if it does then it's a sign for a short circuit. My iPhone cable is a little bit worse for wear, to be honest.
So my question is: Is the problem my cable and if it is is it dangerous if I use this cable to charge my phone with a USB wall charger? 2nd, Is there anyway to fix this other than buying a new iPhone cable?
Thanks in advance!

Thats a warning. if you continually get that warning with the iphone cable and you keep using it. You could eventually disable that USB port.

NF980-G65: USB Port Problem

Hello Everyone,
First post - just set up a new rig with this board before the Thanksgiving holidays.
I am mostly very pleased with this board, except I am having one problem. The USB ports that are next to the Ethernet port aren't working correctly (not sure if there are specific number values associated with those two...).
For instance, I have plugged numerous devices into both of those ports, and the devices never show up in the OS (card reader, DROID2 phone docking station, etc.). I plugged an external WD HDD into both of these ports - it does receive power from the connection, but never loads device drivers in the OS.
Any suggestions on troubleshooting this would be greatly appreciated, thanks in advance.
