Installed the suggested upstream kernel, and the bug also affects it. So I marked the bug with the tag bug-exists-upstream.
Also tried to install the latest Utopic kernel to test with it. Test failed: the Utopic kernel did not recognize not only the usb drive attached through the expressCard adapter, it did not recognize the drive when attached to normal USB2 port. ** Tags added: bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446798 Title: ExpressCard type USB3.0 adapter does not function properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1446798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
