~~~~~~~~~~~~~~~~~~~
Before you do anything with the device you've found, you need to enable
it by calling pci_enable_device() which enables I/O and memory regions of
the device, assigns missing resources if needed and wakes up the device
if it was in suspended state. Please note that this function can fail.

If you want to use the device in bus mastering mode, call pci_set_master()
