Hi,
I pulled the latest version, but being a git noob I'm not sure about
that, is a "git pull" sufficient?

Here is the dmesg output (what I think to be relevant):
$ grep "usb 1-5" /tmp/dmesg.udlfb
usb 1-5: new high speed USB device using ehci_hcd and address 4
usb 1-5: configuration #1 chosen from 1 choice
usb 1-5: dlfb: allocated 4 65024 byte urbs
usb 1-5: dlfb: Unable to get valid EDID from device/display
usb 1-5: dlfb: DisplayLink USB device /dev/fb1 attached. 800x600
resolution. Using 1875K framebuffer memory
I found the sysfs file in a different path, is that ok?
# find /sys/ -name "*edid*"
/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-5/graphics/fb1/edid
# cat `find /sys/ -name "*edid*"`
#
There is no output, I guess that's what Bernie expected.
Bye,
Christoph
