Comment 7 for bug 991004

IMO this should be above "wishlist" importance, because the lcdproc project had to disable a lot of display drivers (such as hd44780-lcd2usb) still relying on libusb 0.1 API, while libusb-compat-0.1 probably would've solved their issues easily. An LCD that worked perfectly with Ubuntu 16.04 is now dead in 18.04.

I fail to see why Debian maintainers are so worried about introducing some corner case bugs while things are breaking completely without the compatibility wrapper. Apparently it's just a matter of packaging libusb-compat-0.1 and making it conflict with libusb-0.1 so that only either one can be used.
