From a78d702beed61956b26c1b6288da868946642317 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Thu, 16 Aug 2007 16:21:35 -0700 Subject: [PATCH] usb quirks: Add Canon EOS 5D (PC Connection mode) to the autosuspend blacklist Recent versions of the Linux kernel auto-suspend attached USB devices. After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints don't seem to wake back up correctly, causing further use with libgphoto2 to fail with a -114 "OS error in camera communication" error. A similar fix is probably necessary for this camera in PTP mode, which identifies as USB product id 0x3102, but we haven't tested this. As part of our testing process, we tried the USB_QUIRK_RESET_RESUME quirk also, it's not helpful in this case.
