Dell Inspiron 1545 :: USB Device Not Recognized
Mar 17, 2013
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 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.
About 3 weeks ago I had the same problem and it self-corrected itself when the latest Windows Update apparently fixed it.
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.

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.
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"

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.

Since yesterday my Dell Inspiron 1545 laptop is unable to detect any USB device connected to it. I tried connecting the device to all available ports of laptop but none of them is working. I tried to update the drivers but in troubleshoot window its showing "No plugin found ..drivers are not loaded" and for any USB device connected to it, its showing "Unknown USB device".When I went into its detail its showing that "digital signature is not present". I tried all the ways like install, uninstall, reboot. But its not even able to install/update the drivers. All my USB devices were getting detected and were working fine till 5th Nov.11 before this problem started on 6th Nov.11 and I changed nothing in laptop also no damage been caused to it.

Since a few days now I get the message'The USB-device was not recognized: One of the USB-devices connected to this computer does not work correclty. The device has not been recognized'. It keeps popping up from my right corner below, every 5 seconds if I don't click it. When I click the message, I get a list of USB devices (ports) there are available. There's one 'Unknown device'. Maybe it has something to do with the finger scan (biometric)? This hasn't been working very good lately..Even when there's no single USB device installed (normally I have a mouse and a Targus laptop chill mat installed as USB devices), it keeps popping up. I tried deleting the USB port from the list (or uninstall it) in Device control, but it seems it keeps happening.
I suddenly got it, I did nothing specific of did not connect any strange devices (except for a projector on the external monitor exit, but that has nothing to do with USB). I also hear the sound for connecting and disconnecting USB devics randomly when I'm on my laptop.

I had to replace the hard disk and reinstall the system from recovery CDs. Trying now to use the 3G connection results in (translated): "No 3G device recognised". I use the SIM card which functions with my pad. I tried then to repair the 3G driver then to deinstall and reinstall it but all without success. I also cannot recognise a corresponding entry in the Device-Manager. How I could get it working again?

Just received my Thinkpad W520 4270 CTO with bluetooth installed. It was a DOS workstation that I installed Win 7 x64 Ultimate on and I finally got all the drivers installed but the bluetooth software says there is no BT device connected to my laptop. I checked the BIOS settings and confirmed the BT is enabled. I even disabled it, saved, then enabled it to toggle. Hitting the Fn+5 combo doesn't trigger the light or any "Found New Hardware." When the laptop first boots up the BT light flashes along with the wifi light and the HDD activity light. I haven't yet been able to load another OS, but I'm downloading Arch Linux and BackTrack 5 to test to see it's possibly an OS issue.
I realize the sticky about the "do not update the bluetooth drivers" but I'm not getting my bluetooth to work at all, not even being recognized by the OS as an "unknown device."

I have tried everything to get this SD card reader to work but to no avail. Even a fresh install of W7/32 ... nothing... Every time i insert an SD card in the slot... i get a message. USB device not recognized ... one of the usb devices has malfunctioned & Windows does not recognize it... I am also just using a 2 g SD card not an sdhc card.
In the Device Manager.... it shows up as "unknown device" yellow highlight... try to update the driver ... says i already have the best driver..... when i take the sd card out...unknown device disappears... i have also re-installed the drivers from here for the card reader... but nothing....
Furthermore... it seems to lead to an error code 43 ..

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.

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] ...

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 .....

Have recently purchased a new 14z. When I turn on the ultrabook, with no power cable plugged in - I get a message telling
me that the Battery is not recognized, and that I should press F1 to continue or F2 to go to the Setup screen. Pressing F1 boots
the ultrabook as normal. It seems a strange message to get. Ultrabook was purchased direct from Dell about 4 weeks ago, and
BIOS is A06 (latest).

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.

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 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.
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 ordered two basic Inspiron 1545's on March 16th. $479 each on the one day special.
Dell says it will arive on April 6th. Does Dell usually take this long to deliver?
Both have Dual Core Pentiums. Can they be upgraded to Core 2 Duo later? Are the CPU's soldered on the main board?
Ram is limited to four gigabytes, even though the laptop uses a 64-bit CPU. Is this something that might be fixed in a future BIOS upgrade?
Is there any way to upgrade the onboard graphics? I found an ExpressCard chasis that has PCI express slots, but it costs over $700. I could build a PC for less than that. Do I have any other options?

I just looked at the pictures and specs of the new Inspiron 1525 replacement, 1545, and I couldn't believe what I have read. No HDMI port, no firewire port, only 3 USB ports, no modem, no eSATA. Also, it is 15.6" 16:9 screen, which is fine, if they offer higher than 1366x768. It is more like the 13" Inspiron than the old 1525 to me. I think Dell is going to re-align Inspiron as a cheap line like the HP Presario line. Dell Studio will compete with HP Pavilion.

My question is if the early 1545's came with LED's or CCFL's? I see all the 1545's now come with only LED screens.
I ask because on the 'Dell Outlet' it doesn't state if it's a LED screen or not. It just says: "15.6 WXGA Laptop Screen Display with TrueLife"
