Common pitfalls

• Mismatched HID report descriptor → Windows rejects or misinterprets touches.
• Incorrect INF hardware ID → driver won’t bind.
• Failing to complete pending HID read requests → touch stops being reported.
• Not respecting SPB/I2C transfer formats (address length, repeated start) → garbled data.
• Blocking in interrupt context — always defer long I/O to work items.

• Binds to the I2C (SPB) controller using SPB (Simple Peripheral Bus) framework or via IoTarget open to the SPB/IOCTL interface.
• Implements HID report descriptor and HID callbacks to user-mode.
• Translates I2C transactions to/from touch controller registers.
