First, please disconnect all USB devices and then
perform the following steps:
Click "Start" button, type "devmgmt.msc"
(without quotation marks) in the "Search" bar and press "Enter".
Click "Continue" if necessary.
In Device Manager, double click to expand
"Universal Serial Bus controllers", right click on the Host
Controller, click "Uninstall" and click "OK".
Repeat the step 2 to uninstall all items under
"Universal Serial Bus controllers". Then, restart your computer
and Windows 7 will reinstall all USB controllers automatically.
what you have a is usb wireless network adapter, which is a device that allows you to connect a usb enabled computer (laptop/desktop) to a wireless router (access point) so you can got connect to a network or go online if your router is set up for it.
you would usually need a driver for your computer to recognize and work with this device. the driver usually comes on a cd with the unit. you would usually insert the cd and follow the instructions, or you would usually also install the drive and then connect the device.
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.
hi there, windows vista, as we all know is more focused on to the security... but it becomes very difficult if it detects other devices as an error...
With vista you can try to run the installation CD for the router, so that the vista knows that there is a driver for that router, without that it will not recognize the router and will keep detecting as an error...
You may need to uninstall your current usb's and let Windows redetect them.
click on START, SETTINGS, CONTROL PANEL, SYSTEM. Click on tab HARDWARE, click on DEVICE MANAGER. Scroll down to UNIVERSAL SERIAL BUS CONTROLLER. Delete everything there. Click on ACTION, SCAN FOR HARDWARE CHANGES. It should redetect and you should be good.
I've run into this issue with USB wireless network cards from DLink, Linksys, and Netgear. For me, the issue was with the USB ports on the PC and not having enough power for the device, the connection would stay live for a random amount of time and then all of a sudden it would die (same thing would happen when resuming from hibernation or standby). I added a PCI card with a powered USB hub in it and it solved my problem.
Seen this happen many times...it stems from a corruption of the plug and play drivers enumeration key in the registry...the fix is quite elusive...the key is cheap...pick a different brand to replace it with save yourself the grief of fighting this battle.
Hope that helps.
