Actually my problem is on usb host mode. I tried it from h-e-n as well as new usb host method from pali. But in both cases it comes massage :

unable to connect, no file system available

But my flsh drive or mouse is lighting. But anything not working.

I installd everything as they mentioned.

finnaly DEB file was downloaded and installed without any problem. But when I run then through exterminal it showed about python above packages I mentioned.
