Subject: [edk2] [Patch V4 0/2] Add Max LUN status/value checks
https://bugzilla.tianocore.org/show_bug.cgi?id=767
Changes in V4
* Fix return status from UsbGetMaxLun().
Changes in V3
* Only check number of bytes transfered if Direction is not UsbNoData.
Add error check to USB I/O Protocol UsbControlTransfer() for the number of bytes actually transfered. If less than requested, then return EFI_DEVICE_ERROR.
Check Get Max LUN status/value in USB Mass Storage Driver to handle cases where USB device does not support Get Max LUN command or returned an invalud Max LUN value.
