Is there any way to detect USB state?

Hi, there, FYI.

Is there any way to dectect the USB state(insert/eject), I want to find such sample,
and it's most probably running under win32/unix/macos.

Thanks.

Qt does not offer any way to do that. You'll have to rely on other libraries to achieve what you want (e.g libusb).

Thanks fullmetalcoder, but I found some Extended interface of QT,
such as QUsbStorageGadget, QUsbManager etc. for Embeded Linux,
Could we use these modules for our purpose?

Where did you find those usb modules? Share the link, if you can.

QtExtended supports USB, but it's only for Embedded Linux, not Win32 or MacOS.

I'm subclassing the WinHost, and to receive the WM_DEVICECHANGE message to detect the state of USB. but on my XP machine, i can not receive the message. :(

for other platform, i want to use libusb.

Is there any other good suggestion? Thansk.
