KM3M-V Unknown devices in IDE ATA/ATAPI controllers

After installing I have two "Unknown devices" in the IDE ATA/ATAPI controllers entry of the Hardware Manager.
Every time the PC boots, it wants to locate drivers for the devices - which it can't since they're "unknown".
Anyone know how to correct this? I'm sure it's the primary and secondary channels, but why are they not identified by Windows
I've installed the drivers from the Motherboard CD, and from LiveUpdate

We're talking about the entries in the IDE ATA/ATAPI Controllers that usually read "Primary Channel" and "Secondary Channel".
The strange bit is, that although the controllers are "Unknown", the devices themselves (HDD, CD-ROM and CD-Writer) works fine.
It is just a bit annoying to have to cancel the two "Unknown" devices each time the machine boots.
Re-installing the mainboard drivers has no effect.

IDE ATA/ATAPI CONTROLLERS MISSING!

I recently had to reformat my HDD using my HP OEM Recovery Disks. Now when I go into Device Manager there is no listing for the IDE ATA/ATAPI Controller. There are no UNKNOWN devices and there are no OTHER devices listed eliminating that question. I have a feeling that I may need to re-flash my BIOS but there are no listings for that software installer in the support for my PC it only shows a BIOS for another MoBo. I was hoping the Recovery Disks would have an option to re-install drivers but it seems that it will only do a comeplete OS Re-Install.
Is there a way I can install the IDE ATA/ATAPI Controllers without having to do a complete OS re-install????
This question was solved.

Yikes! I sure did highlight the wrong slots. Thanks for catching it.
The SATA connectors are to the right side.
I will correct the image for others viewing this thread. Image replaced.

Will it charge when connected to a wall outlet? The USB port on your computer must be 2.0

Hi,
I used to have problem with my Intel workstation when I was running Solaris 8 with ata-dma enabled. The problems disapeared after I upgraded to Solaris 9.
I've been using Solaris 10 b72 for about a month and the problems have came back on the same hardware.
When accessing files from two disks at the same time I get error messages like these in the syslog:

The system is using a AMI bios and the motherboard chipset is VIA KT133.
The system consists of 3 Seagate disks, they are properly jumpered as master+slave + master. I've set up the BIOS to auto-detect the disks.
Could anyone confirm it this is a bug or if Sun has removed support for my motherboard chipset... or any pointers that could assist me in getting my system functional again.
Many thanks,
Martin Andersson

As far as I can see the difference between those drives is slim 12.5mm or ultra slim 9.5mm height. (Are you sure there not Hitachi?) I'm 95% sure the TiBooks will take the 12.5mm drives.I recommend looking in Apple System Profile to see exactly what model you currently have installed and then find one with the same dimensions.

Unknown device - ipod nano fine - problem with windows xp and usb root hub

Greetings all. I've seen this question come up over and over again and have been working on it following previous posts and posts on microsoft and hp sites for a couple of days now.
First off - the ipod nano is fine. Works on my son's computer well.
When I plug it into my 6 months new HP Pavilion laptop it says: 'found new hardware' and goes through the process of installing it, says it's been installed, but then shows 'unknown device'. In Device Manager it tells me there are no drivers installed, but when I try to follow the other instructions on this forum to update the drive to USB mass storage device (usbstor.inf), it tells me the best driver is installed and won't do it.
Many seem to have this problem with devices other than the iPod on Windows service pack 2 so I went to the Microsoft forums and they seem just as puzzled. I've updated all my Windows & HP software to the latest possible versions. The problem is definitely in the USB. Once, when I uninstalled the USB device and then rebooted the computer with my iPod still plugged into the port, it found my iPod, correctly identified it, and for a blissful moment I thought everything was fine! Then it reinstalled the USB drivers and made a comment to the effect that I should move the iPod to a USB 2.0 port for more effective operation and the iPod disappeared again.
I have 3 USB ports on my laptop, all are USB 2.0 and all 3 have the same problem.
I've tried all the stuff people have already said on here...does anyone have any NEW ideas? I'm hesitant to take it in for service because it seems to be a software problem that should be fixable.
Thanks in advance for your help and sorry about the long post.

This isn't a solution, but it's something I just tried and it may provide someone additional clues about's going on. I too think this is some sort of USB problem.
I have 6 USB ports. Two of them are USB 2.0. Since I applied the 03-23 update my computer hasn't recognized my nano at all. I would connect my nano and I couldn't get it to show up in My Computer, in iTunes, or on the far right side of the Start taskbar.
I just tried plugging my nano into the first USB port of my USB 2.0 pair and left the second 2.0 port empty. I then rebooted with the nano attached. Viola - I get a "Found New Hardware Apple iPod USB Device" message. My nano is now flashing "Do Not Disconnect." A small removeable storage icon with green arrow now shows on the far right side of the Start taskbar. If I click on it (like you're going to eject it) the note displayed says "Safely remove USB Mass Storage Device - Drive (F:)".
If I go into My Computer, "Removeable Disk (F:)" now shows there. However, if I try to follow Trevor's instructions in another post to "go into My Computer with iPod connected, right click it, wait till the right click menu comes up (could take a few minutes); click Format, . . ." I'm stuck. I do the right click, watch the hour glass and wait for the Format menu to come up but it never does. Eventually the hour glass just goes away. No message, no Format menu. The waiting hour glass just goes away.
My computer isn't as new as yours, but like you I am completely current on maintenance.
I'm going to keep trying . . . If anyone has any ideas, please let me know.

DVD Burning Error: Unknown device error. (0x73, 0x03.)

I have been trying to burn a home movie using iDVD. I transferred the media successfully to my computer, followed all the steps, and was finally ready to burn the DVD. After waiting almost an hour through the burn process, it spit the DVD back out of my Macbook Pro and gave me the following message.
*Errors were found during the burning process:*
*The recording device reported the media error: Unknown device error. (0x73, 0x03.)*
I don't really know what this means. Was the media corrupt? Or is there a problem with my DVD player? I have supplied my DVD and computer information below. I would appreciate all the help I can get. Thank you in advance!

Using the same media I've used for years (Verbatim 4x InkJet printable) and all of a sudden can't burn from the internal drive. I do have an external burner (7 disc standalone replicator with USB/FireWire 400) and hooked that up and burned to a disc from the same spindle with no problem, and then made a 3x replicate with the same media. So it's looking like my MacBook Pro's drive is failing?

Error message unknown device error (0x73, 0x03)

I created a project in FCP and prepared to burn it in DVD Studio Pro but when I tried to burn it I got this error message : unknown device error (0x73, 0x03). Does anyone have any brilliant ideas on how to burn this?

What speed disc are you using? That burner will only burn speeds up to 8x for DL. You might also try burning at the slowest possible speed.

The recording device reported the illegal request: Unknown device

Has anybody any idea? I am not able to output a dvd-9 (dvd + dl). there is always the message: the recording device reported the illegal request: unknown device. The layersize is ok and the dual layer brake is set.

I don't have the exact error message with me, but that sounds similar. I bought a new DVR-115 for my Mac Pro and put the existing DVR-112 in the bottom slot. The DVR-115 worked fine for a month or so, then started getting that or a similar error. I replaced it under warranty and soon got the same thing. Then I Googled the error message an found many people having the same problem, even people with PCs. Now I just burn with the DVR-112, not worth resolving. BUT, I could be remembering the error message incorrectly, so Google and see what you get.

IPod appearing in Device Manager as unknown device

Hi, I'm currently using an iPod Nano 4th Gen. and it is appearing in Device Manager as an unknown device. I found this out after the error message "USB device not recognised" or something, and followed instructions. I'm currently clueless on what to do. My OS is Windows 8. When I go into properties of the unknown device (iPod) the device status is: Windows has stopped this device because it has reported problems. (Code 43). And in details, I get: USB\DEVICE_DESCRIPTOR_FAILURE
If you need any more information to help me, please do not hesitate to request it. I just really would like this issue to be solved. Thank you in advance.

Thank you for the update, passionflower
I think next would be a good idea to shutdown the computer, and disconnect everything from it. Let it sit for a minute or two, then plug it all back up and turn the computer on, then try again.
Next I would start troubleshooting the USB ports on the computer. I would start with this troubleshooting.
On the Start menu, click Control Panel.
Double-click the System icon.
Click the Hardware tab.
Click Device Manager.
Scroll down the list of devices to the Universal Serial Bus controllers
Click the plus icon next to the Universal Serial Bus controllers.
Double-click one of the indented USB Root Hub entries.
Click the Power Management tab.
Deselect the "Allow the computer to turn off this device to save power" option.
Click the OK button at the bottom of the window.
Restart the computer.
From: iPod not recognized when connected to Windows laptop over USB
http://support.apple.com/kb/TS1401
And then this troubleshooting
Plug the device directly into a high-power USB 2.0 port on the computer. If possible, use a USB port on the back of the computer.
Avoid plugging the device into a keyboard, display, or standalone hub. The USB ports on these accessories may be low-power or only offer USB 1.x connections.
If you are using an accessory, remove the accessory and connect the device to the computer using only the Apple 30-pin to USB Cable or Lightning to USB Cable.
If you have access to additional Apple 30-pin to USB Cable or Lightning to USB Cables, try testing with another if the first one doesn't work.
Restart your computer and device. To restart your device:
Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the Sleep/Wake button to turn it back on.
Disconnect all USB devices from your computer, except for your keyboard and mouse. Then reconnect the iOS device. If the issue is resolved, reconnect other USB devices, testing after each connection.
From: iOS: Troubleshooting USB connection
http://support.apple.com/kb/TS1286
If you have another computer you can also test the iPod Nano there to help isolate whether the issue is with the iPod or the computer.
And just in case the issue is still not resolved, I want to thank you for using the Apple Support Community. Due to the nature of your issue you may find more information by using another one of Apple's support resources - https://expresslane.apple.com/GetproductgroupList.action.
All the very best,

Satellite P775-S7320 Unknown Device issue

Unknown Device
Device Type:     Universal Serial Bus controllers
Manufacturer:    (Standard USB Host Controller)
Location:            Port_#0002.Hub_#0004
Windows has stopped this device because it has reported problems. (Code 43)
I'm trying to figure out what this device is before I open the laptop and start poking around.
Any info would help, thanks in advance.

I can remove all external USB devices and the issue still exists. The internal webcam is USB and working fine, so is the toutchpad but also working fine. I suspect another internal USB device, but I have no idea what else is USB. I don't use the WiDi and wondering if that is considered an internal USB connected device.

IMac shows firewire hdd as "unknown device"

Hi,
I have an Iomega firewire hdd, that a few months ago worked fine with my powermac. Now I have an iMac Intel and it shows the firewire as "unknown device". I've tried plugging the firewire hdd into two different iBooks and got the same result.
When the firewire hdd in plugged in, its blue light comes on. But I can't hear the hard drive working (though I can't remember if it made a noise when it was working properly).
Unlike another post that was similar to this, I cannot change the jumpers, as it is a closed unit.
Does anyone have any ideas?
Thanks!

hmm, sounds as if either the HD has died/ has a loose connector, or the firewire controller had gone kaput, its not that common but can happen, and seing as you have tried it on 2 other Ibooks and still have unknown device that seems to be the case.
I have had an external enclosure that had firewire and it stopped working but when i took the HD out it worked find, just the box died..
as yours is a sealed unit id hope its still under warrenty
Sorry i couldnt be more helpfull

Firewire Bus/Unknown Device?

Hello to all. I just picked up a New 2.3GHz Power Mac and when I was checking the System Profiler in the Firewire section it reads Firewire Bus

Model: Unknown Device
Maximum Speed: Up to 400 Mb/sec

The funny thing is I have nothing plugged into any of the Firewire Ports! The other strange thing is I have a 20 inch Cinema Display (which has a USB and Firewire Hub built into the back of the display) and If I plug that Firewire plug into the Computer I get a Duplicate reading of the info above (looks like this):

I called Apple and They had me run every test under the sun. As a last resort They had me erase the Drive and do a reinstall of just the basic Apple Software and this is what I ended up with. I thought maybe one of you kind folks might have some idea of what the **** is going on.
Thanks

Thanks so much for your replies. So what is the technical explaination for this because I have been on the phone with Apple for hours over the last 2 days send them all sorts of system data. I even mentioned the fact that I have seen postings listed on this forum with other people with the same Unkown Error issue happening to there Dual Core machines and the people I have spoken with at Apple are acting like the have never heard of this before. I only noticed this Unknown Device thing because I am in the Audio Recording business and I am having a problem with my Digidesign DIGI002 interface giving me this slight distortion problem coming out of the 002 unit. But this was happening when I had the 002 connected to my Powerbook 17inch 1.33. I figured it was some type of software issue but now I'm checking into the 002 as the culprit! And the people down at Digidesign have never heard about this Unknown Device Issue as well and think that could be messing up the 002 but I do not have this Unknown Device thing going on with my Powerbook. So I'm stumped!
Thanks again!

Unknown device seen by HH4 and allocated static IP...

I'm setting up a new HH4.
In the list of home network devices it shows an 'unknown' device. It seems it's a wireless device (connected through an access point; the AP tells me it's connected there). I have no idea of what the device is. On looking at its properties on the HH manager, it seems it's been allocated a 'static' IP address, within the normal DHCP range. All my other devices show 'IP address assignment: DHCP' where this one shows 'Static'.
Any idea why this device would have been allocated a static address? As far as I know, this is something I could configure the HH's DHCP server to do (but I haven't); I don't think it's something that the device itself can request. So how does this come about? I'm hoping this information will help me figure out what this device is.
Phil
Solved!
Go to Solution.

Lots of my devices have registered as 'unknown' initially, then I've been able to identify them (using the MAC address, for example) and change the name. But all these have been allocated addresses using DCHP (as I would expect). What's odd about this is that (a) I still can't identify it and (b) it's been allocated a static address. If I understood the reason for (b) I might be able to solve (a).

Annoying "unknown device&qu

I own an Audigy 2 zs notebook. It works like a charm (at the moment I have the driver and software from this thread installed http://forums.creative.com/showthread.php?t=24260)
Everytime I boot up though, I get a message that an "unknown device" needs to be installed. When I press don't ask again, it will ask again anyway, when I press install, it looks on windows update for drivers and identifies the device as "Creative SoundFont Synthesizer" it then tells me that there was an error installing the drivers and history repeats itself over and over again.
I thought that disabling the device might do the trick, but the result of that is just that the windows audio service doesn't boot with windows any more and that I don't get any sound even with my built in audio card. The only way of getting things back to normal again after that is a rollback from a system restore point.
Any ideas how to fix this At the moment I just click cancel everytime the message pops up, but it's probably slowing down my boot time, too.

Before USB took off, PC joysticks used a serial interface and required hardware to convert the analogue movement of the stick to a digital value to be used by the PC. Some bright spark realised that the sound card already has DAC/ADC converters built in so an additional connection was soon added to many cards allowing them to double up as joystick/gamepad connectors.
As MIDI is also serial data, it wasn't long before the same port was being used for MIDI connection and was a very cheap and useful extra. One of the areas where PC's lagged behind Apple and even Atari PCs was in music production so this was quite a big deal at a time when there were no PC based virtual instruments and home keyboards and synths were the biggest selling gadgets in town.
In the last few years USB has been adopted as a means of transfering MIDI data although this is far from uni'versal and actually has a number of weaknesses when compared against the traditional MIDI connection. Despite this, M$ decided to remove OS level support for the gameport with no thought for the millions of MIDI users around the world - they were only thinking of game players - like much of the PC market.
In actual fact, the MIDI ports still work under Vista but can't be configured without dabbling in the registry. Programs such as Cubase can still use them so it's not a total loss. It is possible to purchase a MIDI>>USB adaptor but this just introduces additional problems and costs. There hasn't been any response from M$ as to why they can't re-instate support so the issue will never go away.
If you don't use MIDI or non-USB game controllers you can either ignore the Device Manager entry or right click it and select "Disabled" to make it look tidier.
Here endeth the lesson :-)
