I baught a used P8061-2 Card, which fails to connect to the PC USB Interface:
When I apply the 12V DC Power, LD12 “RUN” starts flashing and LD13 to 20 are permanently illuminated (as described).
When I plug in the USB-Cable, LD10 “POWER ON” gets on, but the PC (Windows 7 / 32 Bit) does not report an unknown USB Device to be installed.
My visual Inspection did not detect any weak points of the assembly quality. What steps could I take to fix the Problem?
For my understandingthe PIC18F2550 is controlling the USB Interface. In case this chip or the firmware is damaged, do you offer the hex-File to be reprogrammed or a pre-programmed replacement PIC controller?
Thanks for your Help
