[lcd4linux] Opening usb display fails without error message

[Marcel <ta...@gm...>]

So here I'm back with svn code from ... about 5 minutes ago. Trying to open my 
c't-includ usb display using the serdisplib (with libusb-support) driver. I 
call lcd4linux like this:

$ ./lcd4linux -Ff ~/lcd4tanu.conf
serdisplib: open(07c0:1501) failed:

This _is_ the complete output, there's no error message. lsusb looks like 
this:

marcel@d-wwow:~/Desktop/lcd4linux$ sudo lsusb

Bus 003 Device 001: ID 0000:0000

(I removed all other device names)

This is my Display section:

Display TanuDisp {
        Driver 'serdisplib'
        Model 'CTINCLUD'
        Size '128x64'
        Port '07c0:1501'
}

Should work like this, shouldn't it? :)
