 # Known issues
 * Suspend / resume doesn't work properly. Suspending must be done with the device closed.
-* Only firmware version 1.43 (latest OSX El Capitan) works with the driver.
+* Only firmware version 1.43 is known to work with the driver. Newer versions might also work but 1.43 is highly recommended.
+* Due to a bug in cpio 2.11 the firmware download script doesn't work. cpio 2.12 or later is required. (See: https://bugzilla.redhat.com/show_bug.cgi?id=1318084)
 * The driver will complain about 1871_01XX.dat (or similarly named) files missing. This error can be ignored. The .dat files contains sensor calibration settings that will improve image quality. The error looks something like this: 
 ```Direct firmware load for facetimehd/1871_01XX.dat failed with error -2```. Ignore it.
 * No /dev/video0 device appears after loading the module. This can be because the bdc_pci module is already loaded. Make sure you unload or blacklist bdc_pci before loading the facetimehd module: ```modprobe -r bdc_pci```.
