Currently supported (tested) : - Luidia eBeam classic projection and edge projection models - Nec "interactive solution" NP01Wi1 & NP01Wi2 accessories. Patch 1 to blacklist the devices for hid generic-usb. Patch 2 is the actual driver. Notable stuff : - use div64_s64 for portable 64/64-bits divisions. - 13 sysfs custom files : 9 values for the transformation matrix, 4 for xy ranges and a calibration trigger. - need userspace gui tool for calibration (ebeam.tuxfamily.org) Side notes : - The module run fine since 3.3.6, both x86_32 and 64. - Already reviewed in 2012 and 2013, but i have'nt pushed for inclusion. - The only recent change is switching to non world-writable sysfs files. - There is a proprietary application suite based on libusb, hope it won't break with this driver. Thanks for your help.
