Hai guys, i have a problem ....... I have a compaq presario R3000 notebook. Its usb ports, LAN slot, Card reader slot are not working. I have installed usb drivers and all the drivers that i could get from the hp site for this notebook. In the device manager, i checked for errors. The usb controllers are shown to be working properly.I have four ? marks for 4 PCI devices, under Other devices.If i check the properties of each ?PCI Device , i got device status like "The drivers for this device are not installed." Guys where can i get the drivers for these PCI devices. I don't even know what are those 4 PCI devices. I got device details id for one of the device as "PCI\VEN_0010&DEV_D020&SUBSYS_00.......".I think that there is a link between these PCI Devices drivers and USB Functioning.The cd drive is present the only way for me to input data into the notebook.I have also entered the DEV and VEN ids in www.pcidatabase.com , and I got the result as "No match found".Please anyone HELP..... Thank you guys in advance.
