Problem: Trying to compile owfs-2.4p1 w/o usb support:
gcc -I../include -I../../../owlib/src/include -fexceptions -Wall -W
-Wundef -Wshadow -Wpointer-arith -Wcast-qual -Wcast-align -Wconversion
-Wstrict-prototypes -Wredundant-decls -D_FILE_OFFSET_BITS=64 -g -O2 -o
.libs/owhttpd owhttpd.o owhttpd_handler.o owhttpd_present.o
owhttpd_write.o owhttpd_read.o owhttpd_dir.o owhttpd_favicon.o
-Wl,--rpath -Wl,/usr/local/lib -Wl,--rpath -Wl,/opt/owfs/lib
-L/home/ptxdist/owfs-2.4p1/module/owlib/src/c -pthread
/home/ptxdist/owfs-2.4p1/module/owlib/src/c/.libs/libow.so -lpthread
-Wl,--rpath -Wl,/opt/owfs/lib
/home/ptxdist/owfs-2.4p1/module/owlib/src/c/.libs/libow.so: undefined reference
to `altUSB'
collect2: ld returned 1 exit status
Fix: only use the "altUSB" variable if we have usb support activated
