Hello,
can we return to this problem ? I tried to get newest SDCC-20080905 and compile
the project again.
Downloaded the PICHID package - http://www.nutsvolts.com/media-files/113/USB.zip
Made necessary changes in usb.c and Makefile - see diffs. In compile log there
are missing some lines about --optimmize-goto and modified dog caaled EVELYN.
But device is not detected at all.
Did you find something for these problems you mentioned ?
Best Regards,
Vaclav
