Hi,

What exactly did you try ?

libusb can be a solution.

None, you have to use libusb directly.

Hi,

A possible other solution could be KDE's Solid framework.

@qt_ankit_developer I don't know. This now has nothing to do with Qt. Search on the Internet. Something I found: https://sourceforge.net/p/libusb/mailman/message/34503180/

@qt_ankit_developer

Are you by chance talking about flash memory drives and want to get their mountpoint?

Then https://doc.qt.io/qt-5/qstorageinfo.html might be of help.

Regards

@qt_ankit_developer

why not just update to Qt5.4 then.
It should just work since its such a minor jump in version.

@mrjj
Hi,

Hi
Well it's so old that the maintenance tool does not have it.

In any case, its not really upgrading. Its either replace 5.3.2 or
concurrent 5.4 installed.
You can download installer from
https://download.qt.io/archive/qt/5.4/5.4.2/

Make sure to backup your Debian
so its easy to go back if something
should go broke.
