The current code has the mcu report a trsync_state message every 10ms
and expects a time extension within 25ms. However, this means that if
a single mcu->host report is lost then 20ms would elapse until the
next report, which would allow for only a 5ms round-trip time before a
timeout error is reported.
Increase the trsync_state timing so that a message is sent every
7.5ms. This increases the total number of messages per second sent
from mcu to host to 133 (from 100). With this change, a single lost
message would still allow for up to a 10ms round-trip time.
