Subject: [RFC ebeam PATCH 0/3] new USB eBeam input driver
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.
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.
