USB drivers going GPL-only in kernel 2.6.25

USB drivers for Linux will be GPL-only with the release of the upcoming kernel 2.6.25.. USB maintainer Greg Kroah-Hartman writes:

"Over two years ago, the Linux USB developers stated that they believed there was no way to create a USB kernel driver that was not under the GPL. This patch moves the USB apis to enforce that decision."

So, Just wait for 2.6.25 kernel release from kernel.org,
Apply the patch or compile the new one to have a full support for your USB systems.
