This patch (as1646) fixes a long-standing bug in the USB hub driver. Upon conversion from char to unsigned long, the bytes in the status buffer are subject to unwanted sign extension. The bytes should be declared as u8 rather than char, to prevent this. This effects of this bug are minimal. The hub driver may end up doing a little unnecessary extra work because it thinks events have occurred on some ports when they really haven't.
