Lcdproc 0.5.9 problem with lcd2usb

After updating to version 168, which also updated lcdproc to 0.5.9, the display no longer works. The display is connected via USB and is addressed via lcd2usb. If you configure it this way and call “/etc/init.d/lcdproc start” the start fails. If you change the driver from lcd2usb to 4bit, for example, the service starts but the display doesn’t work, of course. I would like to try to switch back to version 0.5.7-2, but I don’t know how. Does anyone have an idea or a solution. Greetings Rolf
