This is funny. After I complaint to the seller he made all excuses even saying that the cable got stolen at the post office (Really?), he agreed that the cable was missing and instead of me sending him the scanner back, he purchased another HP-4600 on ebay and sent it to me. He assured that this scanner came with the cable as it was shown on the listing picture and also said that I could keep the scanner he sent before.
3 days later I received the new scanner from the seller he bought it from and guess what? NO FREAKING CABLE.
I contacted the guy right away, he doubted me again and said he would contact the seller. Seller claimed she forgot to ship the cable in the box and that she would ship it Priority on the following day.
After that I decided to try the pinout with the first scanner I received. Took it appart and was actually very easy. The cables are color coded so it was imposible to mess up. What I did here is remove the original cable that comes out of the scanner and replace it with the cable from an Xbox 360 Kinect which uses the same principle, 12v Power Supply to the device and USB and the color of the wires actually matched.
I soldered everything, triple check before power it up and nothing.......Scanner was dead.....Thats my luck.
I undone everything, and took the 2nd scanner appart, soldered the Kinect wire, turn it on and works perfectly.
So first scanner not only had the cable missing, was also dead.
But at least I have one out of the two working now.
Cable arrived today, didn't test it as I already replaced the original cable from the scanner with the kinect cable. I also tested the first scanner again with the cable I received and still dead.
Thanks again for the pinout!!!
