libusb-compat-0.1

libusb-compat-0.1 is a replacement for libusb-0.1. However, instead of being an actual implementation, libusb-0.1 is more of a compatibility layer (or wrapper) which just converts libusb-0.1 calls into their libusb-1.0 equivalents.

It aims to look, feel and behave exactly like libusb-0.1. As it is a replacement, you cannot install it alongside libusb-0.1 on the same system.

As the compatibility layer implements the exact same ABI and API, no modifications to existing libusb-0.1-based applications are needed. You do not even have to recompile them. This compatibility layer is a drop-in replacement.

For more information on the benefits of libusb-compat-0.1 + libusb-1.0, see the libusb-compat-0.1.0 release announcement and these benchmarks.

Status

The compatibility layer is complete and has worked well during testing. It improves USB throughput of all applications that were tested. There are a few minor behavioural differences, detailed in the README, and a few known bugs.
