* There are several variants for 0419:0001:
*
* 1. 184 byte report descriptor
* Vendor specific report #4 has a size of 48 bit,
* and therefore is not accepted when inspecting the descriptors.
* As a workaround we reinterpret the report as:
* Variable type, count 6, size 8 bit, log. maximum 255
* The burden to reconstruct the data is moved into user space.
*
* 2. 203 byte report descriptor
* Report #4 has an array field with logical range 0..18 instead of 1..15.
*
* 3. 135 byte report descriptor
* Report #4 has an array field with logical range 0..17 instead of 1..14.
*
* 4. 171 byte report descriptor
* Report #3 has an array field with logical range 0..1 instead of 1..3.
