Manage USB HID device
Jun 13, 2012 at 3:15pm
Good afternoon!
I've developed a Win32 C++ application (no .NET Framework) that, using Windows API, communicate with an USB HID device.
The application work right but sometimes it fail because enumerating plugged devices does not get my USB device so no communication is established.
Someone knows how the operating system manage USB devices?
Why this happen only sometimes and not always?
Did you work on projects like this?
Thank you in advance!

Similar question to mine I think. http://www.cplusplus.com/forum/windows/73208/
I want to understand how Windows 7 specificallty handles assigning a drive letter to a device. Windows XP is much faster, so it is different. Maybe you could check responses to my question to see if it helps as well.
