Bug Description

Binary package hint: udev

if ndiswrapper module is loaded, udev does not modprobe modules on new hardware. E.g. for bluetooth usb module and btusb module:
-Without ndiswrapper module:

Then I plug the device out, do modprobe -r btusb; modprobe ndiswrapper and plug the device in again:

That's all I get. If I modprobe -r ndiswrapper and btusb and re-insert the bluetooth dongle again, all needed modules are loaded automatically.

The install is a default ubuntu 10.04 with latest updates. I have no restricted drivers installe (save for ndiswrapper). The bug may be hardware-related as I can't reproduce it on another PC with ubuntu 10.04.

I have also this bug on my system. After removing the ndiswrapper module USB hotplugging works again.
