Acer :: Dvd Drive Disappear From Both My Computer And Device Manager
Jan 9, 2009
I currently have an Acer Extensa 5620z-4801. About a month ago, I started using my laptop to burn DVDs. The DVD burner worked just fine for the first 2 DVDs. I used Ashampoo. After those 2 DVDs, it stopped working. I checked on My Computer, and the DVD drive wasn't there. At first I thought it was just temporary, so I restarted my laptop. But then after that, it's still not there, and I freaked out. I checked my device manager to find it, but it vanished from device manager also. I tried to google to find a solution, but doesn't help. I tried that regedit method, but I couldn't find neither upperfilter nor the lowerfilter or whatsoever. I tried removing prime and secondary IDE and reinstall, but doesn't help.

I own a Dell XPS M1730, that is our of warranty.
Recently, my CD Drive failed to read CD's. So, I removed the drive and took the model number off of it and searched the internet for a new drive (since Dell does not sell them). I bought it, received it and installed. It turns on, opens up and the light is on.
Now, I want to reformat my computer but the system is not reading the drive even though it appears to be on. It does not show up in Device Manager, and when I go to the Boot Menu it tells my that it cannot read the device in the modular drive. Yes, the module drive is enabled in Bios.
Is there anything I can do to remedy this or am I forced to send my laptop back to Dell again for repairs (Because that is getting old, and if that is the case then it just going to become a brick to me).

Today I found an error in device manager "unknown usb device descriptor request failed" with error code 43. Then I found out webcam doesn't work/disappear. So I try to fix the problem and reset bios setting seem to get it back.
But in windows when I try to use webcam, at first it seem to work normally but after a few minutes it disappear and reappear immediately. Repeating this a few time it was again disappeared with the same "unknown usb device descriptor request failed" error.
Repeating the same bios thing again and it's back, running normally. Then I leave webcam program on(cyberlink youcam) to observe. It working fine for around ten minutes then it was repeating disappear and reappear again and this time it blinking like in this video [URL] .... so I turn off webcam, leave it for minutes and running youcam again and it's back to normal(Still working normally when I post this (working for around 25 minute now)).
What cause this. Does this mean my webcam is failing?
Also my webcam LED indicator flickering rapidly like the light bulb when turn webcam on and stop flickering when I point the bright light to the webcam. Is this normal?
Right after I post this it disappear and reappear again but only one time not repeating.
Now "unknown usb device descriptor request failed" is back and webcam disappear again.

I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
Device manager lists the device in question as follows:
Device instance path: ROOTSYSTEM001
Hardware Ids: rootiwdbus
Device stack: DriverPnPManager

I have just installed Windows 8.1 x64 on my Lenovo E330.
I downloaded drivers from the website, and installed all of them. But after that there's one device listed as Unknown in device manager, and I can't figure our which device it is.
Hardware ID is {48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver, so that doesn't identify the device.
Info from Solution Centre: Product: 3354AF7
How to identify what driver I missed to install

i bought a acer laptop @ bestbuy and it came with preinstall vista home. i used the computer fine and all and the internet connects to my router find and was surfing the internet. i then decided to install a fresh copy of my own vista ultimate because i dont like the preinstall stuff that they did because it just clutters up space. after i finish my install of vista ultimate, my laptop doesn't connect to the internet. i know this is simply but i dont see network adapters under the device manager in the computer management screen. i am worried because if i have to install the driver, then i would see some icons with a yellow exclamation mark, but i dont see NETWORK ADAPTERS AT ALL. i dont know how to solve this? any help would be greatly appreciated. thanks all. i've tried to press scan for new hardware changes but still i dont see the network adpaters. i thought if you install vista ultimate, then it will install the wireless drivers for you too.

I got my new laptop today, and got rid of the installed Dell Crap and installed my Windows 7 Ultimate 64-bit.
Now under my Device Manager I've got two issues:
Base System
Base System
I contacted Dell, they said they won't support my laptop since I don't have their operating system on it. All I want to know is what drivers I need. I can't believe they couldn't let me know.

I bought two of these laptops (Acer E5-471P CI3 4GB 500GB 14 Inch Touch Laptop - Black. - [URL] .... as Christmas presents.
Both are having issues with the trackpad where it will randomly freeze or the pointer will disappear. At first my mother thought it was just being slow and freezing all the time. I had a look and found that the touch screen worked fine when the mouse froze or disappeared. Now, immediately I assumed it to be a driver issue, so I updated the trackpad driver.
I can't find any info on this and even though I bought the week before christmas ACER are saying my warrenty has run out and I don't have the time to find a scanner to scan my receipt. I am a day or two away from returning this laptop if no solution can be found.
This freezing happens ALOT, to the point my mother is using the 4 year old dusty laptop with missing keys. I assume it's something to do with the touchscreen and the trackpad interfering with one another.

I have an FW490, and noticed when looking at the device manager that under Portable Devices that there was a problem. There is a warning beside something called "R5C592". When I checked under properties it says Device type: Portable Device, Manufacturer: Ricoh, Location: on UMBus Enumerator.
Under device status it says: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available."
I checked for solutions and couldn't find anything. My PC seems to be running fine. Is it possible that it could be that I used a USB key that is causing this problem?

i got my new dv5 last night and ive got a problem. The first time it happened was when i tried to make one of those back up DVD's, i open the disc recovery manager, and the computer suddenly logs off, and im reverted back to the welcome screen where i need to click my name to log back in. Every program that was running simply dissapears. I was like 'crap... i guess i cant make any back up discs'. But then it happened again when i tried to install WinRAR, it was corrupted becuase i copied the files from another computer and after i press ok in the error box it does the same thing.. 3 times i had to re-download a file i was downloading at that time. I guess it only happens when theres an error. I immediatly uninstalled norton and most of the bloatware so it cant be due to that. So now im paranoid about opening any file hoping that it wouldnt log off like that suddenly and lose my work.

I have had to have a new hard drive installed as I got a error message saying old drive failing.
I also had a clean install of windows 7 as I was uncertain whether my discs I created would be ok.
I therefore have not got all of the freebies that were installed on the laptop as new. I now find that the dvd drive is not showing in my computer and nothing happens when I insert disc.

I noticed today that Device manager lists a different CPU to the one in my laptop in the 'System devices' section.
My laptop is a HP DV7-6052ea with I7-2630QM (Socket 988b)
Device manager shows the correct details under 'Processor', listing the I7-2630QM (8 times).
Under 'System devices' it has this line: Xeon E3-1200/2nd Generation Intel(R) Core(TM) Processor Family PCI Express Root Port - 0101
I can't see any details for the 2630QM in the 'System devices' section.
Device manager says all drivers are up to date;
I7-2630QM - 6.1.7600.16385 21/06/2006
Xeon E3-1200 - 9.2.0.1026 10/03/2011
CPU-Z correctly lists the I-7 2630QM and I haven't noticed any problems with my system (apart from some songs skipping a bit) so is this something that is likely to cause problems or OK?

I have a Seagate 1TB hard drive connected via USB as a backup (Memeo-backup software) to my HP Probook 470 G2 (Windows 7 Pro). The Device Access Manager asks me to authenticate myself every 15 min (approx). This is very annoying. Is the solution to uninstall the DAM s/w and what will the consequences be? Or how to get around the Device Access Manager?

I am trying to connect bluetooth earphones to my HP-Pavilion-dv7-6b32us Notebook. I have two different models that I am trying to connect to my notebook: Nextware Sonic and Jarv earphones, both via bluetooth. I've tried "Add a Device" through the control panel, but the devices don't pair or show up. I can't find Bluetooth in the device manager. Are there any drivers I can download or software on the computer I can activate to solve this, or do I need to buy a bluetooth dongle?

I installed a new hard drive on my Niece's laptop Inspiron 14Z (N441Z) and did a clean install of Win 7 Home Premium. I installed the Chipset drivers first and then started on the list displayed in the support area for this machine. After completing all of the drivers install, my device manager looked like this:
The Unknown Device shows an ID USBUnknown. This machine has 1-USB2 and 2-USB3 ports. If I run the Dell Diagnostics it shows that I have 1-1.1 USB ports, and 2-USB2 ports. The 1.1 port appears to works since it will recognize flash drives etc. This is also true of the of USB2 ports. The other USB2 does not recognize anything except my Samsung Galaxy 4 phone. But when it is unplugged I get a balloon on the task bar that says a USB device is not recognized. This will also occur when I first boot up the machine. It is like the machine is not recognizing the USB ports If I run any of the hardware troubleshooters that Microsoft has it tells me that a driver is missing but when it tries and install, it reports that it fails. I have undated my bios, all drivers, I have uninstalled drivers and then rebooted with no luck.
