Select Details - Any messages listed? Errors? In device manager, right click on the usb device that is not recognised The problem is pretty clear now.could i please be provided with an appropriate solution.ĭoes the usb device work without disabling host controller when webcam is listed in imaging devices? The second problem is that if i uninstall usb host that hosts the cam the bluetooth during the next restart is not detected ( device not found ) thus i am now into this frustation that i got to switch ( i.e enable/disable ) either of the devices. i uninstall my host controller ( the one cam is on ) and instantly mass storage devices get detected and are started as normally and i am able to transferĭata.but unistalling doesnt always help.every time i boot my system the host controller is installed again the webcam moves off as 'unknwn device' into USB host category. I have finally figured out a solution.the problem with the solution is that the solution is temporary. Thats the detailed problem of my laptop.hope it would help in properly diagnosing the problem and helping me out soon.īt it cudnt help me.after analysing and trying all the help i could had from the internet i have figured out that there is probably a conflict between the webcam of my laptop and the mass storage devices. Manufacturer : ( Standard USB Host Controller )ĭevice status : Windows has stopped this device because it has reported problems ( code 43 )ĭriver details under the driver tab show : No driver files are required or have been loaded for this device.ĭoes it indicate that one of my USB controller aint able to install the driver for itself which in turn results ' USB not recognised ' for flash drives ? sigh :( The properties window under the general tab shows However i noticed one thing in between that that there is already one unknown device in the list of USB controllers even when i dont plug in any flash driveĪnd the unknown device has a yellow exclamatory mark along with it. I tried all the ways you told me to.but none worked for me :( Please tell me you are talking about which cables ? have installed the latest chipset driver for my laptop.have uninstalled usb hub controllers and rebooted.have tries all those registry tweaks involving deleting upper and lower filters.

When i try plug in a HSIA device for internet connection.
