DJI Datalink receiver - unrecognised device

[modles]

Hey guys

I've just moved away from home brew flight controllers to the world of the DJI wookong, and must admit I'm liking it, enabling things like fly home with the click of button rather than weeks of coding and testing is a good thing

However, I am having a couple of issues with some of the hardware. I'll start of with the datalink receiver. I have the 2.4ghz 130mw version and although the TX/RX seem to be linking and talking to each other (lights green and flashing) I am unable to connect the receiver to my PC.

For some reason despite installing and reinstalling the drivers/software on several different machines, XP, vista and 7, everytime I plug in the receiver I get lovely "USB Device Not Recognized" warning, and obviously it then doesn't show up as a usable com port.

I have even tried various versions of the PL driver but no joy and now I'm completely out of ideas.

So, anyone had a similar issue? or got any bright ideas to try? Would be greatly appreciated.

Cheers

Ben

If anyone has the downlink receiver if they could just quickly check their device manager and see what it says for driver i would really appreciate it. Attached is a screenshot of what mine says..View attachment 9107

I wonder if DJI have been putting the counterfeit Prolific pl2303's in these receivers

I had similar issues with my GCS with LK900 DataLink 900 Mhz.....Even though it is now sold with one free waypoint, you still need to acquire a new serial number or you will get a message "permission denied" when trying to link the GCS thru to the WKM. Previous to that I had two other issues:
a) GCS radio USB cable seemed (2nd head to PC seemed to short out a USB port and knock-out my Notebook PC for 15 minutes. might be a faulty cable
b) Neither GCS nor Google Earth would work......
c) Then Google Earth failed to operate entirely even after uninstall and a re-install.

Now working 100%. No issues with drivers except when installation was done in the wrong sequence.
Do not start by activating the ???.msi program.....
Go to the CD subdirectory and activate autorun from there...... not sure why anyone would hide autorun where it would not run on CD install!!!!!

Also it seems that DJI CD installs two drivers and then Windows also wants to install another driver when you connect the GCS transceiver to your PC.
All two or three seem to be needed.
