HI. I don't really know if it is bug, but i have some problem with usb uhci/ohci/ehci drivers. I have device that if is plugged on linux which is installed on virtualbox/vmware works ok but when is plugged on linux installed on my (and my friend) machine no working:

This shows me lsusb and dmesg command on installed linux:
