Usb not work why ??
Fuses ?

There are no ANSELx registers in the 18F26J50. Check the data sheet:
http://ww1.microchip.com/downloads/en/DeviceDoc/39931d.pdf
The first two addresses you use above are actually the addresses of the
UADDR and UCFG registers. So if you write 0 to them, you are
over-writing the USB configuration registers.

If you want all digital inputs, the following line will do it, in a current
version of the CCS compiler:

Code:

setup_adc_ports(NO_ANALOGS);

But in current versions of the compiler, you don't even need to do that,
because the compiler makes all analog pins into digital pins, in the
startup code that it inserts at the beginning of main().
