Bart allen is to be used to inject USB drivers into images that do not included the USB driver.
One example is the latest nabilo images. No usb are included in the kernel so Barry Allen can not be installed.
Run the Bart allen patch and the kernel will be updated with usb drivers allowing Barry allen to then be installed.
het is dus geen second flash maar een update voor de usb drivers in de kernel waana dus wel barry allen werkt.
