My laptop with windows 7 all of a sudden cannot detect any usb? indication at device manager, usb host controller, there's an unknown device??can u help me what to do?

the Driver of USB Controller is deleted (by a virus or something like that)
and you need to install some drivers.
so put the motherboard driver Disk in your drive and try to update the unknown device in your Device manager
or install complete drivers of the Disk.

Everytime i try to open my webcam, It says "ERROR webcam not found!"

If it is an external webcam, check the connections. Try it in a different USB port, too.

I'm assuming you are running Windows for the OS. On your My Computer icon, right click and select Manage. This opens a Computer Management window. On the left pane, click on the Device Manager.

If there is anything unknown, it will be indicated with a yellow question mark in the list on the right pane, at least it is in Windows XP. Usually it will have identified the type of device that it is unsure of. Right click on the unknown device and choose Scan for hardware changes.

If there isn't an unknown device listed on the right pane, locate one called "Imaging devices." If you see it, right click it and scan for devices. It is probable that you will not see any imaging devices listed as the system is not seeing one to begin with.

Next option is going to the website of the vendor of your webcam or if it's a built in webcam, the vendor of your display or laptop. Most vendors have drivers available for download from their support pages. Once you locate the exact make and model and matched the drivers to that of you operating system, download and install the software. Windows should find it now.

I need to know what the unknown devise after intalling xp on IBM Thinkpad T30

Way to attack this is to find out what isn't working. It will mosty likely be that. However, all the drivers are available from here so I would download them and install them one by one until the device is recognised.
