The problem has reappeared in the latest three Ubuntu kernels, including 3.16.0-31-generic. I can no longer scan.
There seems to have been a change that meant the system started to recognise the card reader in my Canon MP550 printer, so I get messages like: [ 386.757298] usb 2-1.5: SerialNumber: 14E912 [ 386.759466] usb-storage 2-1.5:1.2: USB Mass Storage device detected [ 386.760192] scsi17 : usb-storage 2-1.5:1.2 [ 386.790059] WARNING! power/level is deprecated; use power/control instead [ 387.774767] scsi 17:0:0:0: Direct-Access Canon MP550 series 0104 PQ: 0 ANSI: 2 [ 387.775169] sd 17:0:0:0: Attached scsi generic sg10 type 0 [ 387.779965] sd 17:0:0:0: [sdi] Attached SCSI removable disk [ 413.540101] usb 2-1.5: usbfs: interface 2 claimed by usb-storage while 'KSaneIface::Fin' sets config #1 [ 417.598741] usb 2-1.5: usbfs: interface 2 claimed by usb-storage while 'skanlite' sets config #1 [ 418.123578] usb 2-1.5: usbfs: interface 2 claimed by usb-storage while 'skanlite' sets config #1 I blacklisted usblp, as CUPS no longer needs it, so I can print. But when I tried to blacklist usb-storage, it was ignored. In any case, I do use other usb-storage devices. Is there a way to tell Ubuntu to ignore the card slot inside the printer, so not use usb-storage? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/313504 Title: Scanimage/usbfs device IO error with Canon MP700 scanner Status in sane-backends package in Ubuntu: Confirmed Bug description: Scanimage fails: $ scanimage P6 # SANE data follows 638 877 255 scanimage: sane_read: Error during device I/O In dmesg: [22955.082523] usb 1-1.2: usbfs: interface 0 claimed by usblp while 'scanimage' sets config #1 [22956.440402] usb 1-1.2: usbfs: interface 0 claimed by usblp while 'scanimage' sets config #1 [22956.442197] usb 1-1.2: usbfs: interface 0 claimed by usblp while 'scanimage' sets config #1 [22956.656083] usb 1-1.2: usbfs: process 13214 (scanimage) did not claim interface 0 before use [22956.657216] usb 1-1.2: usbfs: process 13214 (scanimage) did not claim interface 0 before use Ubuntu: 8.10 libsane: 1.0.19-6ubuntu1 sane-utils: 1.0.19-6ubuntu1 xsane: 0.995-3ubuntu2 $ scanimage -L & lsusb Bus 002 Device 002: ID 04d9:a015 Holtek Semiconductor, Inc.
