I think the problem is the suspend-mode implementation. Once your USB2.0 "thing" enters on suspend mode it can't wake up. This state (suspend) is only especificated for 2.0 (ehci) nor 1.0/1.1
Disabling the autosuspend function, things work well, or disabling ehci function works well too. Sometimes, recompining kernel with noapic (disable global autosuspend functions) sometimes works well (I guess I read it before) -- ehci_hcd module causes I/O errors in USB 2.0 devices https://bugs.launchpad.net/bugs/88746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
