The only voltage inputs are NetDCU14 J1 pins 19/21/22/23 (VCFL/+5V/+5V/VBAT).
On older NetDCUs only J1 is for the power supply.
Other connectors never were meant for power supply.

Is USB device not working at all (error message when connecting) or is just Active Sync not working?
If the NetDCU14 is detected (USB Plug with green check mark symbol is shown in taskbar,Microsoft USB Sync displayed in Device Manager, NetDCUUSBLoader works) then you must delete the Microsoft USB Sync device in the Device Manager and connect the NetDCU14 again.
Then it should work.
If the NetDCU14 is not detected at all, then check your baseboard for for USB compliant routing.
Also check if pin 1 of the USB connector is connected to NetDCU14 J7 pin 25. This connection is needed for proper operation.

NetDCU14 uses USB High Speed, so the USB lines must be routed according to the USB High Speed routing guidelines.
Also pin 1 (VBUS) of the USD device connector must be connected to NetDCU14 J7 pin 25 (USBD Detect).

The adapter fits to our NetDCU style display connector and was designed before there were PicoMOD and PicoCOM, so it has the NetDCU prefix.
If you buy the adapter you also get the schematic.
There are two different LVDS adapters, one for 6bit LVDS displays and one for 8bit LVDS displays.
You can give us the name of the display so we can have a look on the datasheet to select the right one.

Please connect the signals from the PicoCOM directly to the LVDS chip, do not use the AHC245 buffers used on the starterkit.

Interfacing the PicoCOM to a LVDS display is no problem.
What resolution do you have? 640x480 has a 25MHz clock.
Please check the LVDS transmitter datasheet for the minimum allowed frequency.

NetDCU14 uses High Speed USB for Host and Device.
Make sure that the USB lines on your baseboard are routed according to the USB routing guidelines

Please send the Wireshark dump file with the PAUSE frames and the traffic to/from the PicoMOD.
Please remove all unnecessary traffic.

Please send a small sample project so we can reproduce the problem here.

A PAUSE frame sent means than someone is sending packets too fast and another device is telling to stop transmission for some time.
Quanta 65535 means a stop for 65535 bit times which corresponds to 33ms for 1GB Ethernet.
See http://homepage.cem.itesm.mx/raulm/pub/mimicry/opodis06.pdf for more information.

Standard setting for Windows Embedded is DHCP enabled.
To change the settings you can either use NDCUCFG as described in the First Steps documentation or you can use the control panel. And don't forget to save the registry.

The additional ethernet pins are between J1 and J2 of the NetDCU8/10 so they is only one 26pin connetor J1 instead of J1 and J2 on NetDCU8/10.
The display connector is like NetDCU9 with a 48pin connector with signals for 24bit TFT interface and analog VGA instead of the 34pin on the NetDCU8/10.
The NetDCU14 has USB2.0 High Speed, so the USB lines on the baseboard must follow the High Speed USB Platform Design Guidelines

Quote from "Jochen0x90h"

it seems to work with
ip-address: 169.254.x.y
subnet mask: 255.255.0.0

This means that the armStone did not get a DHCP IP address or has no static IP set.
In this case it assigns itself a IP through APIPA (Automatic Private IP Addressing).

There is no insulation or filter between GND and GNDC. These signals are the same on the NetDCU and only separated on the startinterface.
The RS232 level shifter is powered from +5V on the NetDCU8 and from +3.3V (from switching regulator) on the NetDCU10.
The data lines and GND have no filters so you might add some on your baseboard.

The polarity of the signal can not be changed.

The NetDCU8 has a linear regulator, the NetDCU10 has a switching regulator.

It seems that something is misconfigured in the display driver, probably the polarity of the vertical sync signal.
Please check the polarity of the sync signals with the display data sheet.
To check the settings we need the display data sheet and the driver settings.
The attached pdf helps you to extract the display driver parameters from the datasheet.

The audio output of the PicoMOD7 is a line out with 1V RMS on 10k. You need an amplifier for a speaker or headphones.
We also have the possibility to change the line out to headphone out, but this is a customer specific variant and only available
for larger quantities. Please contact our sales (<!-- e --><a href="mailto:sales@fs-net.de">sales@fs-net.de</a><!-- e -->) for a quote.

This display can be used with the PicoCOM3, but we do not have an adapter.
The connections are decribed here:

the ET070080 backlight needs 600mA, this is 30% more power than ET057080.
The power regulator on the starterkit is limited to 1.5A, so the probability to overload the regulator is higher.
This leads to resets and other unpredictable behavior.
Best practice is to use a seperate power supply for the backlight.

You need a AutoMDIX capable transformer like WE 749014012.
