Dell Inspiron 14r :: USB Devices Are Not Recognized
Nov 16, 2014
I have three usb ports, and none of them seem to be working. Although the devices work on my roommate's laptop, they are not recognized on mine. When I plug my flashdrive into hers, it lights up, but that doesn't happen on mine. I recently reset my computer to factory settings to try and fix other issues including the problem with the usb ports, but the usb devices are still not recognized.
I recently sent in my laptop due to problems of it not being able to turn on, and my battery and a/c adapter were replaced. I was quite happy. However, I do not want to send it back in even though it is under warranty. Since I am a college student, I really need my laptop. If nothing works, I'll send it back in over winter break so I'm not without a laptop during my studies.
My touchscreen is also not working, so how to fix that, here is my other post: [URL] ...
I keep getting USB Device not recognized on all USB ports on my laptop.  I am running Windows 7 (recently did a restore to clean up computer) service pack 1.  I refreshed the BIOS I tried deleting all drivers, shutting down, taking out the battery and restarting I tried refreshing all USB drivers I tried adjusting the power settings to ensure that all power save mode on USB devices was disabled  Still no luck. Once in a while I can plug something in and it will work for a bit then it becomes disconnected. I think this might be a hardward problem as no software intervention has worked.
I have bought a Inspiron 5421 laptop last week during IT show 2013 Singapore. I found that one of USB port next to DVD drive does not fit any devices. Also encountered Error message when insert a wireless mouse receiver in other USB ports.
I purchased dell Inspiron 3520 with Linix OS. i formatted and installed Windows 7 home premium. downloaded and installed all driver files from dell website. no device is unidentified in the device manager. everything is fine except the blue tooth. Device manager shows bluetooth as working and i can click the bluetooth icon in system tray. but strange thing is it wont detect any Bluetooth devices. another issue i observed is that when i try to install a Dell device driver for blue tooth it will generate an error message "Activate Bluetooth Using Wireless Switch". i tried FN +F2 key but it works with wireless only. i tried PC health checkup utility . and all kind of checking. checked bios whether Bluetooth is disabled. i could not find option to enable bluetooth. tried windows update.
I have recently purchased a laptop Dell Inspiron 5520, & all of its USB ports are USB 3.0, so i am unable to connect my USB 2.0 devices. May i know what exactly must be the problem?? or is it that i can't connect USB 2.0 devices on USB 3.0 ports??Â
I am having problems with the touchpad on my laptop. When I am in the middle of typing I have to watch because it will begin typing where my cursor was laft on the screen. I have to be very careful because I barely touch my touchpad and the mouse will click. I have tried to figure out how to turn the sensitivity down but I cannot find it in the devices. It tells me no devices were found when I click on the mouse folder. I have tried and tried but I cannot find anywhere to change the settings for the touchpad. when I am trying to type a paper and I look up and half my paper is in the middle of a different section or it just hasn't been typing because I have clicked out of the screen.
After installing XP media center on my inspiron 1520 i am unable to get it to recognize usb devices. I looked in the device manger at the drivers and it is missing some for the usb. I am not sure which one to download. I tried installing some and they did not work. I went to dell's site and did not find anything.
recently I bought MS Industrial wifi mice. When I plug adapter to usb port on my Inspiron 5520 it says "Device not recognized" . Then I put it to another port ( I have 4) it says the same message. I plugged it to first port again, and it works.Â
When I put laptop to sleep or when I shut it down and when I wake/turn it on my mice doesn't work . I plug adapter out, and plug in again, the same message .... "device not recognized"
I have a inspiron 15 laptop and keep getting a message "USB not recognized. The USB device attached to this device has stopped working or windows doesn't recognized.." thing is there isn't a device attached to the computer when I get these messages.I've updated the BIOS, driver updates etc and still get the message.
Wondering if anyone else is having this problem with Dell.
I bought an Inspiron 1500 14 months ago. Early on I noted that the adapter dell sent would sometimes slip out if the laptop was touched.
Then at 6 moths I started getting a message on power up -AC adapter wattage & type cannot be determined.- 2 weeks later the battery was drained and the system wouldn't recharge it .....
I have a Dell 1545 Inspiron Computer with Vista Ultimate OS. Yesterday for the 2nd time, my mouse and printer won't work because I get the error message USB Device not recognized.Â
About 3 weeks ago I had the same problem and it self-corrected itself when the latest Windows Update apparently fixed it.Â
I know there is nothing truly wrong with the USB devices but am not sure what to do. If there is a particular driver for this as my backup DVD for this computer has lots of them listed. I am currently running a System Check but am not sure if that is going to work.Â
I have been using the same wireless mouse on this computer for three years. Suddenly it stopped working after a Windows update last night. Getting the following:USB Device Not Recongnized.
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. I have uninstalled USB drivers and let windows reinstall them, no change. I did a restore back two days, then windows wouldn't start. Occasionally stops in Dell start up screen and gives 4 beeps. Undid restore, back to same problem stated above.
I replaced my WD 250GB RPM 5400  with a WD 500GB RPM 7200 and I  get a "No boot sector on internal hard drive"  "No bootable devices" I have both original disks ( Operating System  Windows 7 and Applications.) I've checked the BIOS and it shows the new HDD. I put the Operating System CD in and started the computer than I hit F12 went to CD/DVD and hit enter I received the message "No boot sector on Internal  hard drive" "No bootable devices"
Alright I am a long time user of Dell products, and have in the past had problems with them, but they have been easily fixable by either replacement parts or a quick look at a FAQ or messageboard for Info. My INSPIRON 1501 is not recognizing my battery. The battery is fine (checked it in my brothers computer), and I have checked other people's posts with the same problem and tried the fixes but nothing worked. I have tried to do the BIOS update (A16) that worked probperly but did not fix the problem.
While watching a movie I got a message telling me that my battery is not recognized. The battery is stuck at a 97% charge (or so the computer says) and the battery light is not light up (it flashes on sporadically but not consistant at all). The BIOS did fix the message at startup saying the battery isn't recognized but still if I remove the AC power cord or unplug the computer it powers right down and will not start-up unless plugged in.Â
Left shift key is not working, I used my dell application to troubleshot, it recognized all keys, like if I press alt it tells its alt and so on, but when i pressed left shift it showed a message "key pressed". so I concluded left shift is working but not being recognized.
I'm hoping this is in the right area. I have a Dell Inspiron 9300 It's upgraded about as far as it can go. I use a desktop for the occasional gaming or rendering but this is my daily driver.
The issue. I took it apart the other day to see if my screen hinge could be replaced and to install a DVD burner. Now it no longer recognizes the onboard/integrated keyboard. It still recognizes the touch pad but not the keyboard. I went as far to buy a whole new OEM keyboard. Still nada.
Brand new laptop 3 days old - model 7737. Came with Win8 and touchscreen was working fine
Have updated to 8.1 and installed other software like office, etc and touchscreen is now not recognised. System says "no pen or touch device"
Device manager also shows an unknown USB device (device descriptor request failed) Device manager also keeps refreshing (like every few seconds) - sometimes the USB device disappears completely then comes back again as unknown.
I'm sure this must be a driver issue but have tried all those I can find.
My laptop's USB ports are no longer working. I believe that some internal circuitry got fried after I plugged in a USB powered device that had its own power supply. I don't remember exactly what I did because it was while ago. I still like to use the laptop, but without USB its uses are quite limited.
When I plug in a device, nothing happens. It is neither powered nor recognized. All USB ports are affected.
My wife has an Inspiron Mini 10 which I damaged seeing if I could upgrade the RAM. So I bought another mobo and fitted it in, plugged it in and turned it on. After so long we were told that the battery was running low and wouldn't charge. After it shut down we got the OLOD and have tried using a USB drive to flash the BIOS using HP USB key utility but there wasn't enough power left in the battery to do anything.
Next I bought a new battery which has about 37% on it but we're still getting the OLOD after booting up and down a few times.Â
From what I can gather from searching the web, I need to flash the BIOS but I can't find a way of doing this as the BIOS files from Dell are .exe and isn't recognised when I boot from the USB stick as it's looking for a .bin file.
It has occurred to us that maybe the drivers (we have Win7 32bit installed) aren't there.
What we should do with the remaining battery power? We don't have enough to experiment.
1/ install drivers?... if so how do we do this without a floppy drive or disc drive?
2/Would a fresh install of Windows fix this problem?
I just bought this new computer, an inspiron 17r se 7720 and whenever i try to open the nvidia control panel it says that in the system there isn't an nvidia graphic card when actually its there.Â
The graphic card its an nvidia gt 650m with 2gb of dedicated ram. I tried to flash the bios to the latest update but nothing. What can i do?
I have a 2 year old inspiron 15 (M5030) running win 7 and have had 2 problems that keep coming up
1) I run the dell diagnostics in the Dell Support Center for my hd and it keeps coming up "targeted read test failed" how do i fix that
2) I keep getting the message "USB Device Not recognized" message pop up constantly especially when I'm using my laptop on my lap when I don't have anything attached to a USB port. How do I get that to stop popping up...
I got XPS 15 (9530, Late 2013) couple of days ago with widnows 8.1 installed on it and since the day 1 I am running into a weird problem. All of my USB devices keeps disconnecting. Whether its my phone (HTC One M8) or my portable harddisks. I have tried multiple cables and the result is the same.
I tried connecting all of those devices on different laptops and they work fine except for my laptop. One more thing is that if I have my phone connected with the laptop, it charges fine however, I am unable to browse any file on my phone because it keeps disconnecting.
My M1730 can’t boot to Vista. It says in red “FAILED”. Also says It can’t find any bootable devices. I did do the test (The one where you press F8 I think) more than once.
I just got my Windows Vista Home Premium OEM disc from Newegg today, I left my original dell one in storage back in NY. It can boot from the disc, but it can’t repair my laptop. So is the HDD dead or what? =/
I have a problem, which seems to be a common problem with Win 7 and bluetooth but I have been searching the far reaches of th einternet for 4 hours no with no luck.
My laptop finds the bluetooth hardware and installs drivers automatically, and says it is working correctly, but it cannot find any devices, it just says "searching" and never finds anything.
My XPS m-1530 is running XP-Pro, clean-installed via instructions on this forum. It runs perfectly . . . except for one thing.
Every once in a while, especially in the middle of a lengthy download, everything stops and the screen goes right to this message: No bootable devices found.
Error Code 2000-0141. This used to happen very infrequently, but now it is more often and scary. I have removed and reseated the HD twice.
