http://bugzilla.opensuse.org/show_bug.cgi?id=920067 Bug ID: 920067 Summary: Canon LiDE20 USB scanner issues with Acer laptop [intel] + USB3.0 controller (xhci) Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: x86-64 OS: openSUSE 13.2 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: madworm_de.novell@spitzenpfeil.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0 Build Identifier: In short, the scanner works just once and then things hang. Sometimes reconnecting it "fixes" things for a short while, but it is essentially unusable. I have tested this scanner with 4 computers: * Old AMD-based PC with USB 2.0 (13.1): works all the time * Even older AMD-based PC with USB 2.0 (13.2): works as far as tested * Old Intel-based Laptop with USB 2.0 (13.2): works all the time * Brand-new Intel-based laptop (Acer) with USB 3.0 (13.2): no go I have experienced crashes / hangs using: (logfiles later) * scanimage -L * xsane Setting up the scanner using "Yast2-scanner" seems odd. Sometimes it shows the scanner associated with the suitable "plustek" driver, sometimes it shows as "not configured". Something is badly wrong. It appears other people have had issues with USB 3.0 and scanners with the "xhci_hcd" driver. I tried to blacklist it, but without it I don't have ANY USB on that laptop. I have tried the latest default kernel (3.19.something), same issue. Reproducible: Always Steps to Reproduce: 1. Attach scanner 2. Try to use it 3.
