Description:
|
||||
Writing a device ID to this file will remove an ID
|
||||
that was dynamically added via the new_id sysfs entry.
|
||||
The format for the device ID is:
|
||||
VVVV DDDD SVVV SDDD CCCC MMMM. That is Vendor ID, Device
|
||||
ID, Subsystem Vendor ID, Subsystem Device ID, Class,
|
||||
and Class Mask. The Vendor ID and Device ID fields are
|
||||
required, the rest are optional. After successfully
|
||||
removing an ID, the driver will no longer support the
|
||||
device. This is useful to ensure auto probing won't
|
||||
match the driver to the device. For example:
|
||||
# echo "8086 10f5" > /sys/bus/pci/drivers/foo/remove_id
