Previous commit missed an unsupported-device-flash-LED check.
...
NOTE: Downstream's full-speed host controller is flakey when connecting
to low-speed devices. One mouse enumerates on only 50% of connection
events, while another mouse enumerates on 90% of connections. Grrr.

Increase SPI interface speed 4x, to 5.25Mbps. Required modifications to
...
SPI peripheral library. At this speed SPI requires ~60% CPU time at -Og
optimisation level. This could be further improved by trimming down the
SPI interrupt. But...
Speed is now limited by Downstream's single-packet-per-URB restriction,
to about 460kB/s. USB Middleware does not implement TX FIFO empty
interrupt, so a bit of work is required here.

Completed moving Upstream to interrupt-based SPI.
...
Although I am not entirely convinced this is necessary, as the SPI data
stall issue only appeared with optimisation off (-O0). Perhaps re-visit
this if Upstream needs more free CPU time later...

Added priority elevation to Downstream USB host processing code that
...
interacts with SPI.
It elevates to USB_OTG priority to avoid preemption by SPI, DMA, or USB
interrupts thus avoiding synchronisation issues between USB host stack
and SPI interface.
Also minor improvements to Downstream error handling.
