|"XP didnt recognised any of my USB devices."|
Have you dropped the laptop, or have you spilled any liquid on it, or have you exposed it to any liquid, e.g. rain, whether it was running at the time or not, since the last time the computer worked fine ??
The USB controller(s) must be enabled in the mboard's bios Setup. It is (they are) enabled by default.
USB devices may not work correctly when they're connected to certain USB ports e.g. ports in a hub or on the front of a desktop case. If you have a desktop computer, you may have an IRQ sharing problem you need to fix, or your power supply may be starting to fail.

Also - if you are using a USB extension cable, some of them have inadequate wiring and will not work properly with some USB devices.
" 2. Planned to reinstall XP
3.Setup Copied FIles from CD to Hard disk .
5. Got a disk read error."
How far did you get in Setup ?
Did Setup reboot the computer just once, then you got the error, or did you get all the way through Setup, then you got the error ?
A disk read error for which drive?
The hard drive ?
Check your hard drive with the manufacturer's diagnostics.

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
A disk read error for the optical drive or the CD ?
You should NOT GET ANY errors reading files from the XP CD during Setup ! If clicking on "ReTry" or similar did not help, you need to fix what is causing the problem BEFORE you can install Windows successfully !
If you DO / DID get errors, something was not right !
