Sorry for the delay, I got pulled off the project to do firefighting on
another.

I cleared the log and repeated the install (with the same result), and
uploaded it here: http://www.accesio.com/files/setupapi.dev.log

Based on my amateur reading, three times it doublechecks the .INF's
signature, failing the first and passing the second of each pair; but it's
ultimately the .SYS that fails, with "Error 0x800b0109: A certificate chain
processed, but terminated in a root certificate which is not trusted by the
trust provider.", and error code 52 is a cascade error, at "Device not
started: Device has problem: 0x34: CM_PROB_UNSIGNED_DRIVER.".

We opened a support incident for this, and it ended up being signing without
cross-signing.
