Subject: USB hub port reset
Date: Sun, 13 Nov 2016 03:52:56 +0000	[thread overview]
Message-ID: <AT5PR84MB02769CBB7CD17B80AB4C8FDEBABD0@AT5PR84MB0276.NAMPRD84.PROD.OUTLOOK.COM> (raw)

EDK2 have reset recovery time of 10ms for hub port based on port status reset bit but USB spec doesn't mention that port status can be used for t6/reset recovery time. Could you please clarify?

USB vendor mentions EDK2 doesn't have reset recovery time on hub port reset and also highlighting EDK2 hub port reset differs from https://github.com/torvalds/linux/blob/master/drivers/usb/core/hub.c#L2789
