Hello Greg, I'm sorry for the inconvenience. I was not sure how to use [RFC] well. If the patch works well, we already don't need to add RFC in the subject line? This patch works fine on my target. If it is not needed [PFC] ,I will send the patch again without RFC in the patch title and subject line in email later. Best regards Yasushi Asano 2020年8月10日(月) 16:45 Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>: > > On Mon, Aug 10, 2020 at 09:19:35AM +0900, Yasushi Asano wrote: > > From: Yasushi Asano <yasano@xxxxxxxxxxxxxx> > > > > According to 6.7.22 A-UUT “Device No Response” for connection timeout > > of USB OTG and EH automated compliance plan v1.2, the enumeration > > failure has to be detected within 30 seconds.
