* Name: usbhost_trformat1 and usbhost_trformat2
*
* Description:
* This interface must be provided by platform specific logic that knows
* the HCDs encoding of USB trace data.
*
* Given an 9-bit index, return a format string suitable for use with, say,
* printf. The returned format is expected to handle two unsigned integer
* values.
