I reinstalled all the libraries and the update package. I made a quick test and so far it seems to work now. If the problem occurs again I guess I’ll need to try different disk then. Thanks for your help.
Actually I already did that but unfortunately there was no errors and it didn’t solve the problem. I also checked power settings for all usb ports and tested 3 different ports. Maybe I could try to uninstall libraries and install those again to different folder.
