Hi Henry,

Frankly you can do it as well as Device Manager can do it and 
as well as you can do it with another device via Device Manager.

For this you need to study how some functions of setupapi.dll 
and cfgmgr32.dll work. you can download my code from codecentral: 
(Borland C++ Builder) - http://codecentral.borland.com/codecentral/ccweb.exe/listing?id=21175
(C#) - http://codecentral.borland.com/codecentral/ccweb.exe/listing?id=20338

See also my articles from codeproject:
.NET - Diving into System Programming (Parts 1,2,3)
http://www.codeproject.com/csharp/DivingSysProg1.asp
http://www.codeproject.com/csharp/DivingSysProg2.asp
http://www.codeproject.com/csharp/DivingSysProg3.asp

Really I do not disable and enable devices but I am sure 
that it possible via CM_Set_HW_Prof_Flags function from cfgmgr32.dll with flag CSCONFIGFLAG_DISABLE or CSCONFIGFLAG_DO_NOT_CREATE.

May be it is subject for Part 4 in codeproject...
