With some super-speed USB mass storage devices it has been observed that a USB transaction error may occur when attempting the set the device address during enumeration. According the the xHCI specification (section 4.6.5) ... "A USB Transaction ErrorCompletion Code for an Address Device Command may be due to a Stall response from a device. Software should issue a Disable Slot Commandfor the Device Slot then an Enable Slot Command to recover from this error." To fix this, retry the device slot initialization if it fails due to a device error. Change was verified using a superspeed mass storage device that was occasionally failing to enumerate in UEFI. With this change this failure to enumerate was resolved. This failure was also only seen in UEFI and not in the OS.
