USB2 devices not functioning to USB2 speeds on K7N2 Delta-L

Dear all,
Before i get the "Use search" button, i have and done it practically all day trying to find a solution.
My system: MSI K7N2 Delta-L, running on Windows XP service pack 2
4 USB ports at back panel, 2 USB ports on the D-Bracket (where there is a High Speed sticker on it)
All USB ports front or back "work" but not any allow me to use a USB2 enabled device to make it function at its designated speed.
An example is: Transfer of a 20MB file takes 25seconds... ludicrous for a newly bought Kingston 1GB USB2 complaint flash drive.
I have read the stickys, i am certain the USBOC is not connected by any wiring, the manual in K7N2 already stated that, my BIOS is at the latest version, my system is functioning correctly, no IRA conflicts by checking through device manager.
http://www.apxc57.dsl.pipex.com/Connections.JPG
This shows that the USB2 Kingston device does not get routed to the Enhanced host controller, i do not know why, please let me know if you know!
http://www.apxc57.dsl.pipex.com/Front%20USB%20unplugged.JPG
A better view...
Standard Enhanced PCI to USB host controller - I'm not as certain to understand what this means. Does it mean that my board ONLY supports the Enhanced USB IF i purchase a PCI card that has USB2 ports on it??? And it means that ALL 6 of my ports onboard (including the D-bracket) are all Open HCD..........
I honestly have searched everywhere and there is NO definitive solution to this problem i'm having yet, MUCH MUCH appreciated if anyone can give a guiding light.....please !!!
THANKS VERY MUCH IN ADVANCE...

Interesting update... here:
I've been thinking about what everyone said here, so i was questioning whether this Kingston USB2 device is really USB2 standards.
Please take a look at here: http://scan.co.uk/Products/ProductInfo.asp?WebProductID=245123
That is the actual product and where i got it from, please just take a quick nip at the specifications.."Super Hi-Speed 24MB/sec"
As you know, i have the MSI D-Bracket 2, the exact image is found here: http://www.modsynergy.com/Modsynergy%20files/MSI-5.jpg
You can see from that image, that it clearly displays a "High speed, certified USB" from the red/blue logo.
A description that distinguishes between "High speed, certified USB" from "Certified USB" can be found here: http://www.everythingusb.com/usb2/faq.htm
Near to the lower end of the page.
Now... interestingly i now notice the back cover of the USB2 Kingston drive in which it was concealed in, take a look here:
http://www.apxc57.dsl.pipex.com/KINGSTON.jpg
Cast your attention to the Red Circle i have done. It doesn't say High speed certified, it just says Certified USB.
SO, let me quote from "What are USB Hi-Speed and USB Basic Speed logos? These logos are part of USB Promoter Group?s branding program that ensures the quality of USB products. The USB 2.0 certified products would display a blue, white and red logo, bearing the words ?Certified? and ?Hi-Speed.? The classic USB 1.1 certified products would display a black and white logo with the words ?USB? and Certified.?"
If my USB2 kingston device is really USB2 and support the 24Mb/sec transfer rate, the box should in fact have a high speed logo not a black/white one correct???
Thanks for reading, i'll get in touch with the supplier i think... probaly RMA come saturday.

Error: Media In Device Not Functional

I keep getting the error message, but only occasionally, when I connect my iPod Classic to my car. I have a factory cable so that I can access the content through the navigation but several times/week the iPod stops (sometimes mid song) and tells me "Media In Device Not Functional". The dealer has done a couple of "patches" that they said would fix it but it hasn't. I'm beginning to think it's the iPod itself since we have an iPod dock for our home stereo and it too was have issues with the iPod. I'm thinking of doing a Restore.

Relieved to hear I'm not the only one with this problem with the 80gb classic, I Opened mine on xmas day and it worked ok for a few days then I got the problem as described...
the ipod played music and videos fine but windows wouldnt detect it so I couldn't sync it ... tried a factory reset (hold action and menu button for 10 seconds) this didn't make any difference, I then managed to get it into diagnostic mode by doing a factory reset, then holding the action button and the left arrow before the apple logo disappears ... after going through all the keypad diagnostics which passed windows again recognised the device, I then opened Itunes which recognised that the ipod had a serious error and offered to restore it back to its factory settings, which I did, I then also updated it to the latest software
again it worked fine for a few days and then I got the same error in windows xp again ... thinking the drivers might be corrupt on my PC I tried it on a different PC but with no luck, again got the same error
My Ipod is now back at Comet ... but because of their stupid policy I cannot get a replacement as it was bought more than 14 days before I took it back, even though it wasn't unboxed till christmas day!! so it looks like I'll be without it for a while,
I will keep posted on the outcome but any other feedback would be appreciated from anyone who has had the same problem

VGA at PCI 3, not in AGP, Why?? (K7N2 Delta - ILSR/5600VTDR

hi...
When i enter to see the properties of my VGA card adapter, it is in the "PCI 3"bus, why doesn´t it in AGP bus ??
i downloaded the "DMI info", the PCI 3 is "in use" and the AGP is "available".
Is there something wrong ??
my configuration is:
K7N2 Delta - ILSR
MSI GeForce FX5600VTDR 128Mb
512Mb DDR
Athlon 2.4 tb

Have gone into your bios and adjusted your chipset settings? If not you need to change a few things first of all your default settings for vga are set for PCI so you'll need to change that to AGP. Second your memory usage will need to get upped from 64 mb to 128mb. Next you'll want to enable 8x speed and fastwrites these will increase video quality.

CPU Fan Speed on K7N2 delta 2 Plat.

Which is the best average in RPM of a CPU Fan? In this case, to my Mobo System.
Thanks.
Amd Sempron 2400+ -- 1.67 ghz
K7N2Delta 2 Platinum
400 W PSU
512 mb Ram
120 GB SATA
120 GB IDE Drive
GeForce 6600 GT AGP 8X
Windows XP SP2

I would say speed within 2500 and 4000 rpm should be the right speed cpu fan for your configuration.

Hi,
Could you please have a share with your phone's information?
Based on what I know, different phones may have different softwares developed by the manufacturer to make the connection through Windows operating system, we may check with the phone's manufacturer side and see if there could be some helpful information
offered.
Besides, please take a check with
Event Viewer and see if any special errors logged there.

Can not drag files off iphone onto windows 7 Laptop (Error: A device attached to the system is not functioning!) Any ideas on how to resolve this, Much appreciated

Connect phone to laptop, AutoPlay Box appears, click open Device to view files, internal storage, DCIM, Drag all Pictures/Videos into folder on desktop. Message pops up within a few seconds, Saying 'A Device Attached To The System Is Not Functioning.'
Can any be of assistance?
Many Thanks.
Callum.

Is the computer in question connected to the Internet, and if so, is the Internet connection working correctly?
It is possible that Adobe Reader tries to check for updates when it is launched, then finds a faulty network connection.
Check the Device Manager for non-functioning network devices.
Also try http://fixitcenter.support.microsoft.com/ to find other potential problems on that system.

I got this message when saving photo from Iphone4s to my laptop's folder. "The device attached to the system is not functioning" What can I do?

I cannot save photo to my deskstop. When I copy to my folder, it indicated "The device attached to the system is not functioning". I don't update my IOS to the latest version in case my photo from my iphone will be missing. Please help. Thanks.

The Only thing I could do to save my pictures on my computer was to send them via Facebook chat to myself, send them one by one then on your computer open then and dragging them is way faster than right-click Save As. I just did that and I do not want to reset my phone so I guess I will continue doing this as I get more pictures or until I feel like resetting my phone. I believe this issue happens when you Connect and while transfering one or more file from one end to another, and you suddenly disconnect the iPhone or any apple divece, the file that wasnt completely transfered gets corrupted and I guess the whole /Picture/Video folder or perhaps the whole device gets corrupted as well. I am sure that this is a cause to this issue but I do not know if there are other causes or if the same one happened to you.
How to prevent this from happening again?
Always go to iTunes and click on "Eject" under your device tab before disconnecting your device from your computer. Even if you are not transfering any files at all.

Java.util.zip.ZipException: a device attached to the system is not function

getting a java.util.zip.zipexception : a device attached to the system is not functioning error - what could cause such an error?
My program finds all zip files in an archive and then searches through them for xls files, which it extracts and re-locates.
I havent even a clue where to look for the cause of this exception but Ill attach at the bottom the code in the general vicitiny of the trigger so that you can get kind of an idea what Im trying to do, and if im lucky, even spot my problem. :) Thanks!!
//zips is an array of zip files
int found = 0;
File[] haveXLs = new File[zips.length];
for (int i = 0; i < zips.length; i++){
String fileName = new String("L:/Vision/Archive/" + zips.getName());
ZipFile archive = new ZipFile(fileName);
String name = zips[i].getName().substring(0,8);
for(Enumeration e = archive.entries(); e.hasMoreElements();){
ZipEntry entry = (ZipEntry) e.nextElement();
if(entry.getName().substring(0,8) == name){
haveXLs[found] = zips[i];
found++;

Hey there a few things.
Make sure that you dont use fileseparators like you do. ("/")
Use the separator generated for your system.
Something like:
String sep = System.getProperty("file.separator");
You mentioned it work local, but not network.
Either you have plenty of harddrives or L: is a mapped drive.
Is it working at the mapped drive?
When you say on the network, how are you accessing the files?
Could it be possible for another user to lock a file, so you wont have access to it over the network?

'a device attached to the computer is not functioning'

I ran into an error today importing files from my iPhone5 to my PC. The error read:
'a device attached to the computer is not functioning'
It happened repeatedly for certian (larger) files that I would attempt to transfer.
The solution, I found was to ensure that I was using an authorized iPhone lightning cable. The cable I used first was a $7 knockoff. It works great for charging, but data transfer is sketchy.
Plugging into an Apple-made cable made the problem disappear!

There were stories published that indicated some companies built and sold lightning cables before Apple had finalized the specifications for them. The cable you purchased might have been one like that. Apple certifies cables the meet the needed specifications and that info appears on the packaging.

When accessing shared folder - 'You might not have permission to use this network resource" .. A device attached to the system is not functioning

On a Windows 2008 R2 server that had been working fine, all of a sudden some shared folders became inaccessible. Clicking on them returned the following: "<Folder> is not accessible. You might not have permission to use this network
resource. A device attached to the system is not functioning."
If I create another share with a different name for that same folder, it works fine. If I delete the original share then recreate it with the same name, I get the same error. However, if I right click on the problematic share and select 'map
network drive' that works. So this would not appear to be a permission issue.
I discovered this problem because the path for mapping the home folder as a property of their AD account stopped working.
I have tried most of the common things found on the internet. I've tried accessing via IP, same issue. While I only have a couple 2003 servers, those can access this resource.
At this point, I'm pretty much out of ideas. Any help would be appreciated. I also have some reports of potential issues with some printer mappings too which I will have to investigate in the morning.
If anyone has a solution to this I would be extremely grateful. Thank you.

Hi,
Can you access the shard folder locally? Is a specific server cannot access the shared folder? Please try to Boot your server in Clean Mode to check if some third-party software cause the issue.

Communication problems: A device attached to the system is not functioning.

Hi all,
I'm developing an applet and using the OMNIKEY 5321 CL reader for communication and testing. One of the requirements for our card is to read large binary data.
For this purpose i used extented lenght APDU to read the data from card.
When I tested it via JCOP simulation I was able to read up to 32767 bytes as described in specification. But problem occurs when I test it with reader, in this case I'm able to read max 298B in APDU response. When I send greater byte count than 298B i have got following error in JCShell plugin:
jcshell: requestSessionKey.jcsh[1]: Error code: -6 (Card terminal error)
jcshell: requestSessionKey.jcsh[1]: Communication problems: A device attached to the system is not functioning.
Regarding the extend lengh APDU support it should by OK from the OMNIKEY. I'm using newest driver 1.2.9.2 for Win 7.
Here my configuration:
JCOP:JCOP 2.4.2r1
JAVA CARD: jc301
Global Platform: gp22
Can somebody help me? Any ideas?

If you want to use PC/SC directly, I have a simple Go program that reads an APDU file (just hex encoded APDU strings) and sends them to a smart card. You can give that a try if you like.
The code is at: https://bitbucket.org/safarmer/go-apdus
There is a Goclipse project as well as the source. You will need to install Go and run "go get github.com/ebfe/go.pcsclite/scard" to install the required PC/SC wrapper. Once you have done this you can run the program with -file <apth to text file>

Access share on NSS4000 with error: A device attached to the system is not functioning

Hello,
We use Acronis True Image Server to backup 4 Windows 2008 Standard Server system
with 2 different domains, each containing a DC and a RDP-Server.
After Server reboot, backup will run only once a day.
The next day backup aborts, and while trying to access
the network share like \\ip-address\share, as configured in Acronis
I get the error message: A device attached to the system is not functioning.
On the other hand, I can ping the NSS4000 and access share by using the
network (netbios) name instead of the ip.
This will work only for one day, also.
Now, if I try to access the share on the NSS4000 again by ip,
I get the error code 0x80070043 The networkname can not be found.
Ping on ip and netbiosname works.
Share access from one server to an other is not affected and full funtional at all times.
On the first sight I thought, that there it might be with the authentication protocol NTLMV2.
So I configured the GP to send only NTLM Authentication only, without fixing the problem.
Fyi:
I use a NSS4000, Firmware version 1.16-3
The NSS4000 is not a member in neither domains.
I created a dummy user account on each domain, an created a local user on the NSS4000 related
to the dummy user account on each domain.
A good answer helping me to fix with this issue, would be great.

I am constantly seeing this error at multiple sites on Windows Server 2012 and 2012 R2 Standard and DataCenter.
I have counted over 50 different server I manage with services such as domain controller, hyper-v, file servers, exchange 2013, SQL 2008/2012, and print servers.
I have seen it happen on machine that have been in production for over 2 years and to machines that were just created last week.
It is happening on metal, hyper-v and esx vmware servers.
It is happening when the machine have updates waiting or no updates, or after updates have been applied and awaiting a restart.
It is happening on Dell PowerEdge server, HP Proliant servers and IBM servers.
It is happening on servers with Intel and AMD chip-sets.
It is happening on machines that are a part of a domain or in a workgroup.
It is happening on machines with AV of Bitdefendor, Trend Micro, Vipre, Microsoft Endpoint, and Symantec Endpoint.
Only a restart will fix it.
I have ran process monitor on several of the problem machines and I cannot find anything.
Since I have only started seeing this about 6 month ago it must be a Windows update causing it.

Direct Show causing "A device attached to the system is not functioning"

Hello,
I've been using direct show for about a year to connect to four webcams. I have an intermittent problem where by one of the cameras (at random) will not display the live feed. This could not happen for several weeks possibly months and then suddenly the
camera dies.
I run the following bit of code and receive error code -2147024865.
IMediaControl mediaCtrl = (FilterGraph)m_filterGraph as IMediaControl;
hr = mediaCtrl.Run();
DsError.ThrowExceptionForHR(hr);
In Hex this equates to 8007001F. From doing a bit of googling I found that this means a "A device attached to the system is not functioning".
No other application uses these webcams and nothing has changed to them physically. Direct Show, seems to make this camera unusable at random times.
Has anybody else experienced this problem and over came it?
Thank you in advance,
Mike

Hi Roman,
Thank you for your reply. I'm using a Logitech webcam and this camera is used by the Logitech controller software. This allows us to control the zoom, pan, focus and camera settings whilst connected to the camera in C# application. When this problem occurs,
the webcam device still shows up in device manager and the settings of the webcam state that the device is working properly.
I thought it may of been introduced by a possible memory leak that causes the camera to not respond, or that when the application closes it would leave the camera in a unusable state.
I've contacted Logitech to ask about drivers for the webcam and they state that it uses windows plug and play drivers. These are currently up to date.
The reason I thought that it may of been introduced by direct show is because these cameras have been used before on other products but using different software, Steribar (a software tool to use the view of a webcam as a cheap barcode reader), and haven't
experienced this problem with the cameras with this software. However very intermittently the custom C# app that I have created causes this problem.
Thank you for you time.
Mike

"A device attached to the system is not functioning"

Hi!
I'm hoping that all the smart people here can help with my problem. I help support/develop several custom windows application. One of these applications is written in Delphi and there is currently a problem with a feature a single computer owned by a client.The client's computer does have the latest version of adobe installed.
* The user is able to select a document from a data grid, and click a button to view that document (in this case a pdf).
* The document is saved from a database to the user's disk
* Using a shell command, the application asks windows to open that file.
Normally this works quite well, until recently. If this client tries to view a pdf file in this manor windows returns a system error, error 31, and the message "A device attached to the system is not functioning" is displayed. If I naviage to the location where the file was saved to an attemp to open it via double clicking, adobe reader opens the document right up. The application historically has had no problems with pdf's nor any other doucment type. If I change the file assoication from adobe to note pad, the application does open the file with note pad, but it is not readable. If I change it back to adobe reader, the problem persists. I've tried uninstalling adobe, reinstalling, and using a previous version of adobe. Any suggestions would be appreciated.
FYI, before someone tell's me I should be talking to microsoft, I am also inquiring on the windows side of this through msdn. Since I am not 100% sure if this is a windows or adobe reader issue I would appreciate suggestions on both sides.
Last but not least, incase it is of any help, this is the delphi command used to ask windows to open the file:
ShellExecute(GetDesktopWindow, 'open', PChar(TempFile), '', '', SW_SHOWNORMAL);
Any and all help is appreciated.
Thanks!
Louis

Run the same code on an XP 64 bit box and it works? XP comes in multiple flavors.
Perhaps you should compile to x86 CPU and see if it works on Win 7 64 bit. Win 7 comes in 32 and 64 bit also.
On the other hand Win 7 service pack 1 mainstream support ended on the 13th of this month. Extended support ends in 2020 supposedly. Perhaps you should upgrade to Win 8.1 instead. Win 10 is coming soon enough.
