[edk2] [Patch V2 0/2] Add Max LUN status/value checks

Posted by Michael D Kinney 7 years, 1 month ago

https://bugzilla.tianocore.org/show_bug.cgi?id=767

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.
