I haven't had a chance to test the upstream kernel yet, but I upgraded my workstation to Raring, and with 3.8.0-5-generic, I can now run my benchmark without the card-reader being powered off. However, it's slower than when I use the same card and card-reader plugged into a USB2 port.
With 3.8.0-4-generic, I was still experiencing the same problem with the card-reading powering off. So between the -4 and -5 revisions, something change that seemingly fixed the problem, aside from the performance issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/904412 Title: 1033:0194 USB3 card reader hangs/powers off when connected to USB3 port [NEC uPD720200] To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/904412/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
