This is the common problem, If this problem solved then we have copy these three files from your pc (they are Windows' USB drivers):
a. Hccoin.dll (c:\WINDOWS\system32)
The following are found: C:\WINDOWS\system32\drivers)
5. Copy them to their respective locations via floppy (yes, I said floppy) or cd by booting to an MS-DOS prompt
6. Once you have them copied – the USB keyboard and mouse will work.
