This normal. Driver will however try to recover the transfer by resending the same trans= fer 3 times (soft-reset internal endpoint) before giving up and and doing a hard reset of the endpoint. Soft reset is useful if transfer error was caused by electrical interferenc= e, but this case the soft rest if futile, device is gone.=20 Not sure if it makes a difference but could be worth testing if skipping the soft reset impacts SRE. Can be done by setting quirk: xhci->quirks |=3D XHCI_NO_SOFT_RETRY --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
