I have dude set up on ac2 and the data is stored on a usb flash drive.
After upgrading from 7.7 to 7.8 Dude will not start.
Analysis showed that the status said no database file was found. The data path looks like disk1/dude. I try to open the files, but the folder is empty. I look at the usb devices and see now my flash drive is called usb1-part1.
I change the data path in Dude settings to usb1-part1/dude and everything worked.
The changelog 7.8 only says
*) usb - changed USB auto detect behavior to default to the external USB, when no internal USB devices detected;
Keep that in mind if anyone encounters the error.
