[PATCH] hid-core: Add Clear-Halt on the Interrupt-in endpoint
This patch (as577) adds a Clear-Halt call on the Interrupt-in endpoint
during input device configuration. Without it my HP USB keyboard doesn't
work.
Vojtech says it's worth trying, since it might help with some recalcitrant
devices. On the other hand, it might interfere with others. I'm
submitting it so that it can get tested by a range of users.
