Hi,
I successfully install the CDM 2.08.30 WHQL Certified drivers on my laptop running Win 7. However, there is no serial USB port that pops-up in the device manager as stated in the manual.
I have tried this on two different laptops without success. What can be the problem?
Nothing happens either when I connect the USB-cable from computer to printer. No LED’s blinking on the circuit-board of the printer.
When I connect the power cable a green LED flashes shortly.
The driver only pops up when the printer is connected to the PC.
On the other hand when you connect your printer to the USB port 2 LEDs should glow (red and orange).
When you plug the printer in the mains the USB LEDs switch off.
Hi alfa,
do you have any other USB device with a matching connector (Mini USB B), that you could use to “test” the cable?
The USB chip on the controller board is (partially) bus-powered, so the voltage drop along the cable should be minimal. Either use the short cable that came with the printer (if you didn’t do that already), or try another good-quality USB cable. Maybe a powered hub could also help, if the issue is indeed related to bus-power.
If the cable checks out and nothing else helps, look for possible errors on the board itself. Is the socket connected to the board or is there a pin that looks suspicious? Does the USB IC (the one next to the USB socket, labeled “FT232R”) get hot when the USB cable is connected?
Cheers,
kuraasu
Thanks for your replies.
I have now tried another cable just to make sure but there is still no response whatsoever.
I cannot see any errors on the board but I’m no expert in these matters.
The IC you mention labeled “FT232R” is not getting hot.
As I understand there should be two LED’s that light up when connecting the USB-cable. If this is indeed suppose to happen there is no such response on my board.
Anyone from Velleman who can respond? I have a strong feeling I have gotten a faulty board but I’m open to suggestions.
If you are positive that the board is at the cause of troubles, you can return it to your distributor for inspection/exchange, or direct to Velleman:

I have tried to describe the issues that I have had with the installation and connection of the printer. With the help from some forum members I have done some basic tests and still get no response from the USB-connection.
If there are no other suggestions from you on things to try I will send it in for exchange.
