"new" version of libusb

My CCID driver uses libusb-1.0 to talk to USB readers.

libusb evolution stalled


The latest version 1.0.8 of libusb-1.0 was released in May 2010 (nearly a year ago). Since then many bugs have been reported and most have been fixed in the git repository. The problem is that now new stable or 1.0.9 version has been released since May 2010. So if you suffer from a bug in libusb it is not easy to update it.

libusb git snapshot

To ease the use of a more up-to-date version of libusb-1.0 I made a snapshot of the version in the git repository and provide it on my web page of beta versions or http://ludovic.rousseau.free.fr/softwares/pcsc-lite/

The files in the libusb git repository have not evolved in the last 6 months so I do not expect to have to make a new snapshot within the next 6 months. I sent a mail on the libusb mailing list.

Conclusion


So before reporting a bug in libccid first try a newer version of libusb. If the bug is at the communication level it may already be solved in the libusb snapshot version.
