Hi,
New USB input driver for eBeam devices.
Currently supported (tested) : - Luidia eBeam classic projection and edge projection models - Nec "interactive solution" NP01Wi1 & NP01Wi2 accessories.
In fact, 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.
So, the code :
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 with a 3.3.6 and a 3.5.0 kernel, both x86_32 and 64.
Thanks for your help.
