OK I have just this moment tested one of many AGFA Snapscan 1212u scanners that we have here with a 2.6.22-7-generic kernel and I can again state that they are not directly affected by the USB autosuspend option (I have not changed anything on the old Gutsy LiveCD and the scanner worked "out of the box"). I waited 3 minutes after plugging in the scanner before running xsane. Checking /sys shows all autosuspend parameters are 2. Doing an acquire preview scan after waiting 3 minutes results in an image being displayed (but upside down). This snapscan has an external power supply. lsusb: Bus 002 Device 004: ID 06bd:0001 AGFA- Gevaert NV SnapScan 1212U.
I have now just retested a CanoScan LiDE 60 here directly after snapscan. I waited 3 minutes after plugging it into the USB port before attempting an acquire preview scan via xsane. All /sys autosuspend options are unchanged and are at 2. The preview shows an image of what is on the scanner (correct side up). It has no external power supply. lsusb: Bus 006 Device 005: ID 04a9:221c Canon, Inc. -- some usb_devices fault if usb_suspend enabled https://bugs.launchpad.net/bugs/85488 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
