Hi,
I found this :
http://69.10.233.10/KB/cs/HardwareHelper.aspx
This article basically concludes that it's impossible to know which device
was added in a direct way, but you need to monitor the entire device-list for
changes.
I can hardly believe this :-( , this calls for an API extension IMHO.
The WinCE implementations is so simpel.....
But, accepting the above, let me simplify the question :
Suppose I have determined which device changed .
(I can get things like DEVDETAIL structure for it)
Where can I find the devicename ? (like COM1
In one sample I found the device is opened using a long string from
devdetail called "devicepath". But this looks quite differrent,It has PID and
VID and a GUID in it. Thats not what I'm looking for, just the short
devicename. (COM1,KBD1 etc)
Any suggestions ?
I need the INTERFACE_GUID (not the class_GUID) and the devicename.
note this will be written in C++.
Greetings,
Rob.
