Hi Balbi, I uploaded one new version patch in new email thread. Please help to review again when you have time. Thanks for the review effort and help! This patch is needed in order to pass one test case defined in the OTG Automated Compliance Test specification. Specification location: http://www.usb.org/developers/onthego/otgeh_compliance_plan_1_2.pdf This test case uses PET Tool, and PET Tool is one USB hardware equipment provided by MQP Electronics. Test case id is 6.8.3 B-UUT Bypass Capacitance. We must set this otg flag in order to be able to return OTG descriptor during enumeration, otherwise this test case with failed with below error: "Get OTG descriptor request stalled".
