Yes it is, please contact the company about this to get the source code
for your device.  If you have problems with this, please try the Linux
Foundation's form for this type of thing at:
	https://www.linuxsources.org/content/open-compliance-directory-request-contact-information
as it works really well.

Disconnect the device from the driver by writing the device id to the
"unbind" sysfs file for the driver that is controling the device.
Examples of how to do this in detail should be on the web somewhere, I
think I wrote a lwn.net article about this a long time ago...

good luck!
