Dear, support team.
Our customers are conducting USB 2.0 compliance tests.
Chapter9 L1 Suspend / Resume Test fails.
Test report output
・ "Port did not go to L1"
・ "INFO Port never went to L1"
・ "FAIL (USB: 9.6.2.1.10) A device that supports LPM L1 must enter L1 at least 1 HIRD / BESL value."
Therefore, it seems that TUSB9261 is failing because it does not go into L1 (Sleep state).
Does TUSB9261 also support USB 2.0 LPM (Link Power Management) and Sleep state?
If so, can you comment on the possible causes?
Is there a similar case (Fail in the above test item) so far?
Best Regards,
Hiroaki Yuyama
