I have a USB HUB. Some things don't really work well if plugged into the HUB, eg. my Canon scanner only works in USB 1.1, not 2.0 mode (that is, without the ehci_hcd module). Maybe there's a problem with ehci_hcd and this HUB?
lsusb says my HUB is: Bus 001 Device 004: ID 05e3:0606 Genesys Logic, Inc. -- USB devices are not recognized when having ehci_hcd modprobed https://bugs.launchpad.net/bugs/88746 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
