Currently supported (tested) : - Luidia eBeam classic projection and edge projection models - Nec "interactive solution" NP01Wi1 & NP01Wi2 accessories. >>From basic usb point of view, all these devices are indistinguishable : they have the same usb ids and (blank) hid report descriptors. There's other re-branded hardware that need to be test, but i bet on same ids. 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. The module run fine since 3.3.6 kernel, both x86_32 and 64, actually run in production on a 3.8.13 and compile without errors on today's linus tree. Side note : - This driver was first submit and discuss last year. Thanks for your help.
