Don't know yet. I intend to use some lower level functions which likely
haven't changed but haven't got there yet.
I've already patched the testlibusb.c (which comes from libusb by the way) to
compile on older libusb versions hopefully.

Mike,
what non-optional features only present in libusb 1.0.23 does Hamlib require?
Surely the libusb version present when building can be detected during
configure and the sources adjusted with macros to suit the older libusb
versions? This after all is what the configure phase is all about.

I simply can't guarantee future compatibility but will try to maintain it.
That's why I put in the testlibusb.c program to catch this type of thing before
it's mandatory and before I implement some things under libusb.
Hamlib has already been patched to allow this to compile now.

In my opinion, the hamlib code should be changed in order to accept
libusb in older 1.0 releases, while avoiding to include the additional
functionalities provided by 1.0.23. As I can see, many recent
distributions have libusb < 1.0.23.
Best wishes,
