Subject: [RFC ebeam PATCH v4 0/2] new USB eBeam input driver
Date: Thu, 23 Aug 2012 00:11:52 +0200	[thread overview]
Message-ID: <> (raw)


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.
