Subject: [Patch V4 0/2] Add Max LUN status/value checks
Date: Fri, 17 Nov 2017 10:19:04 -0800	[thread overview]
Message-ID: <20171117181906.14380-1-michael.d.kinney@intel.com> (raw)

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.
