Have tried several times on both ports on my laptop. hmm. while writing this post, my phone suddenly mounted and showed up in lsusb.. hmm magic? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1072278 Title: lsusb hangs forever To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usbutils/+bug/1072278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
