I'm trying to break this down further:
This block is the set of keys which I've included the byte output for in
a reply further back, repeated for clarity. This block is currently not
interpreted by the kernel as anything I guess due to the vendor specific
page:
0x06, 0x31, 0xFF, // Usage Page (V
The USB descriptor for the affected device:
0x06, 0x31, 0xFF, // Usage Page (Vendor Defined 0xFF31)
0x09, 0x76,// Usage (0x76)
0xA1, 0x01,// Collection (Application)
0x85, 0x5A,// Report ID (90)
0x19, 0x00,// Usage Minimum (0x00)
0x2A, 0xFF, 0x00, // Usage M
The key thing I've noticed here is that if I grab the device via libusb
and capture data, then it's on interface 0x83, and the bytes are a
little different to the keys that do work (like vol+).
For example Vol-Down gives:
[2, 234, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
Apologies, the last attachment is Linux capture data (as per filename)
