Hi Sipter and Marcus, Xenia has a potential fix for a long-standing bug in the xHCI driver, and I need your help testing it. You ran into that bug back in Feb 2013: http://sourceforge.net/mailarchive/forum.php?thread_name=CAGjSPUAQ8phZFu9dj60wt9zZpoghcQMVUAwgd2y3NvLmiAZH7Q%40mail.gmail.com&forum_name=libusbx-devel The issue was that gphoto2 unconditionally cleared a halt on all endpoints after the camera was closed. This triggered a bug in the xHCI driver, making it so gphoto2 couldn't talk to the device on a subsequent open. You worked around the issue by removing the clear halt in gphoto2. Now Xenia has a potential fix for that bug, and she needs help testing that fix. Would it be possible to add that clear halt back into gphoto2, apply the following two kernel patches, and make sure gphoto2 still works? http://marc.info/?l=linux-usb&m=138116117104619&w=2 http://marc.info/?l=linux-usb&m=138116117204620&w=2 Hi Pratyush, I believe you also ran into this issue back in Sept 2012, when you were running usbtest #13 (Endpoint Halt Test) under a TI xHCI host. The tests failed for devices under xHCI. If you can still reproduce that issue, can you try the test again with the two patches? Hi Yuliya, You ran into this issue as well, back in Oct 2012. You added a set interface to your driver to work around the issue. If you're still working on that code, can you take the set interface out, test these two patches, and let me know if your device works?
