Universal Serial Bus Controller Driver Lenovo Download ##HOT##


Can anyone please provide me with the correct drivers for the universal serial bus (usb) controller for HP 15-af153sa? I have several USB ports that I currently cannot use due no drivers after an OS reinstallation.




Universal Serial Bus Controller Driver Lenovo Download



For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.


thats all the info i can find on the properties page of the item, can anyone tell me the appropriate driver to download, or where to get it, i have tried most of the drivers from the drivers download section of dell support and also tried win 7 cab download for the E6520. no luck in any of those. I also downloaded some drivers that just extract to a given folder and have no installer, i have tried to scan these places using the find driver option on the device properties but it keeps saying it can't find the driver for your device.


When you install a fresh copy of Windows on the computer you will need to install the drivers in the correct order for the hardware to work properly. The Bus Controller is the Chipset Drivers. Click the link below to download the drivers. There is also a link with information installing the drivers in the correct order.


hey, thanks for the info, i tried to reinstall win7 and all the drivers but it's still missing the universal serial bus (USB) controller, the thing i dont get is, i have another universal serial bus controller in the devices panel that does install properly when i run the chipset driver, but that's an intel device and has 7 things within its expanded view all installed properly but in the "other devices " expanded view sits the one that's not installing properly, the one i have given the info for in my first post. any further help with this would be gratefully appreciated.


hi again, I don't know what your telling me, Should I not be installing the chipset driver or what ? all i need to know is how to get the other device usb controller to install properly, i dont think its an intel item as i have installed the intel chipset driver and all appears to be ok under the intel usb controller device. This other device is unclear as to what its needing to be installed properly ?


after searching google for a while , a lot of comments are pointing to a Renesas Usb Controller, other people have had success with downloading and installing the driver for this item but i cant find or download the correct driver ? does the dell latitude e6520 have a Renesas USB controller inside it, am i on the right track ?


i dont think its a lenovo that i am having the problem with, in the pic you can see its a dell laptop, the info i gave in my first post is from the properties page for the problem device. in my other post and lots of others i read, other people with dell computers had downloaded and resolved there issues with the driver i mentioned. I dont know if you are telling me to download lenovo drivers or something but i dont think that's the way to go. I will try your other link to see if i can get any more info.


If none of these methods worked for you, you can disable the Selective Suspend feature. However, be aware that when the Selective Suspend feature is disabled, all USB host controller drivers (and therefore all USB ports and connected USB devices) in the system are affected. Therefore, your computer cannot suspend any USB devices that are connected to it, and the USB devices can continue to use power while connected to the computer. Additionally, the Allow the computer to turn off this device to save power check box does not appear on the Power Management tab for the USB Root Hub.This section is intended for an advanced computer user. You can disable the USB Selective Suspend feature as a workaround by editing the registry. The USB device may become unresponsive because of a race condition in the Selective Suspend feature. The Selective Suspend feature suspends the USB device to efficiently maintain battery power by enabling the computer to turn off the USB device. However, sometimes this feature may not correctly wake up the USB device. Therefore, the USB device is unresponsive when you try to use it. You might want to disable this feature for server products where power management is not important or required. Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
