I have an application that reads and writes data to a Compact Flash card via USB card reader. The cards are not formatted on the PC and do not use FAT or NTFS. However, I can read/write to them by accessing \\.\PhysicalDrivex My problem is that the application needs to detect when the user inserts/removes a CF card. Everything I've read says that a WM_DEVICECHANGE message is sent when this happens. However, my application only sees this message when the card reader is inserted/removed - no message appears to be sent when the actual CF card is inserted into the reader. Can anyone help?
