Not working ec2a
I bought an unopened ec2a as defect for 4,- Euro. Just wanted to test the shape, and thought maybe I could get it working again. If not I could swap in the g403 pcb.
Here is what I checked:
- Cable is good, tried the original and a paracord I made with matching pin arrangement.
- internal usb connector is fine, no faulty solder joints, same for the 3310 sensor.
- looked for the 3310 datasheet und checked IO voltage (pin 7) and VDD (pin 10 + 11) both are at about 3,3V
The cpi indicator led lit up in red green and blue at the same time for maybe 1/10 sec when I plugged the mouse in. Then the mouse installed correctly in win7 but does nothing, no clicks, sensor, cpi button nothing is working.
Is there other things I can check? Does sb. know if the behaviour of the led could indicate whats wrong with the ec2a?
Thanks in advance!
