Computer does not recognize Huawei E 1550 (3G Wireless Modem)

Huawei E 1550 - Computer does not recognize; Device Manager says an unknown device is plugged into a USB Port. My Huawei E 1550 has stopped working. Yesterday, it was working fine and I was downloading some music from youtube, suddenly in the middle of download a message flashed that the file was unreadable and hence the download was incomplete, while I came back to the Mobile Partner User interface, it was all white. I tried to close Mobile Partner, but it did not respond. The Task Manager also reported that the Mobile Partner was not responding. I was unable to do anything on my computer and hence was compelled to force shutdown of the machine. On restart of the computer, the machine could not detect the E 1550 device, even the Device Manager says that an unknown device was plugged to a USB Port. Any Idea? What should I do? Thanks in advance.

    Thanks everybody for your suggestions - I had already tried all the 3 suggestions posted so far (19:00 Hrs on 17 Jan 2013). Infact I have 2 such modems and 2 SIMs - bothe the SIMs are working fine with the other Modem, the other modem is also working fine on all computers / laptops with different OS - i.e. WIN XP and WIN 7. Only this perticular Modem is not showing in 'My Computer" area, and unless it is shown there, I can not use the User Interface. In case of this particular Modem, the Device Manager shows it as an unknown device - both in WIN XP and WIN 7. Though I am not a computer geek, yet what I suspect is the modem got updated itself while I was surfing the net and the new updates have somethiung to do with this problem. I am posting the technical details of my other Huawei E 1550 Modem - both were purchased at the same time - the details are .... .... AND the AND the ... ... if somebody could guide me about the link wherefrom I can download these files or some tweaks that could help me. Thanks in advannce

SOURCE: Mouse not recognized/ mouse port not working

I kept hold about 30 seconds the blue light button on the USB controller device and it worked!. I guess that's the way to sinchronize both the mouse and the USB controller of the mouse. Ramón.

SOURCE: MTP Device Searching Preconfigured Driver Folders

I was having this problem as well, but solved it.
I, like others decided to just buy a USB cable for my VX9900 and use Windows Media Player for sync'ing. (I also have the Verizon Essentials program that I downloaded, but I like WMP better. No particular reason).
I was getting the installation messages and as soon as the MTP message came up, I got the "problem" message and it didn't sync.
What I did when I got the cable was to run the CD drivers that came with my cable. That may have been my mistake. I was bothered that the date of my driver was in 2005 since the phone came out late in 2006. So I looked at the name of the driver and it was something like C:\Windows\System32\Drivers\LGUSBDriver.xxx whatever... I went to my device manager and uninstalled the driver. I went to the C:\Program Files\ and deleted the LG USBDrivers folder. I went to the Windows/system32/drivers folder and there were three LG*.* files I deleted them. The next time I plugged the phone in and set it to sync, it worked. It's late and night and I may not have typed this really clearly, so feel free to contact me at bill (at) halfamind.com (because a half a mind is still a terrible thing to waste).

SOURCE: My external hard drive is unreadable

Does you drive make any sounds like these? If yes you have a mechanical problem and you should get a specialist to work on it. If not - try to remove the drive from USB casing and connect it directly to your PC or put into another USB enclosure. This should help if the problem is with the enclosure itself and not with the drive.

Toshiba laptop just purchased does not recognize UM 150 even though driver has been installed on computer. What is the problem?


You are referring to the Verizon wireless modem?
And what is the operating system?

In Windows you can check the device manager to see if the device is working and if the driver is installed.
If you plug it, you should at least see a device in the "Unknown" category. You can right click it and see what the error is. Try to install the drivers from there by specifying the driver location.

There are more causes for usb device not recognized problems.

I reformatted my tosh. satellite, what happened to my wireless? why am i not able to find my adaptor in device manager?


Did you reinstall from the Toshiba-supplied "System Recovery" CD-ROM, or from some other "retail" Windows XP CD-ROM ?

The Toshiba CD-ROM contains the device-driver.
Toshiba's web-site also contains the device-driver,
for use in a situation like yours.

Within Device Manager, look at the "Unknown Devices" branch.
Expand that branch, then double-click on the '?' device,
and choose "reinstall driver", and allow Windows to connect,
via Ethernet cable connected to a router, or to a cable-modem, or to an ADSL-modem, to the Internet to find and download the correct driver.

Usb device not recognize


You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.

To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.

My device is no loner recognized


Go into the device manager, click on View > Show hidden devices. Look under unknown devices or under USB for unknown devices. Also check under the section relating to the type of usb device. If you find an Unknown Device, or a device with an exclamation point, right click on it and uninstall. Disconnect the device, reboot and install the drivers/software for it if any. If it's still not working check it in another computer. If you cannot get it to work in either machine, the usb plug of the device is probably damaged. Possibly a loose solder joint. Have the manufacturer send you a new one if its still under warranty.
