Public bug reported:
Using Ubuntu 8.04.1 on a Toshiba Tecra 8000 with USB hub shown below.
Often, when I plug a device to the hub, nothing happens.
This lasts as long as I decide (minutes).
Then I type the lsusb command, showing no device indeed.
That simple fact (issuing lsusb) connects the device.
A subsequent lsusb command shows the device connected.
More details available on request.
Contact welcome with developper to run tests.
Continue the excellent work.
Glad to contribute (wso,od).
André.
