./configure: line 4449: syntax error

trying to build got syntax error in configure:

./configure: line 4449: `PKG_CHECK_MODULES(LIBUSB1,libusb-1.0)'

And I did sudo apt-get install pkg-config libusb-1.0 already

Same here. If you're like me, I didn't install pkg-config until I got the error you reported. But then after I installed it and re-ran ./configure the error was still there.

Some digging around brought me to this: https://stackoverflow.com/questions/8578181/using-the-pkg-config-macro-pkg-check-modules-failing

The issue seems to be that there is a macro called PKG_CHECK_MODULES which won't be replaced with real code by the bootstrapping steps unless you have pkg-config installed.

Anyway, the solution for me was to re-run ALL the install steps AFTER installing pkg-config. Then the ./configure step succeeded.
