USB Attached SCSI

modulename: uas.ko

configname: CONFIG_USB_UAS

Linux Kernel Configuration
└─>Device Drivers

In linux kernel since version 2.6.37 (release Date: 2011-01-04)  
The USB Attached SCSI protocol is supported by some USB
storage devices. It permits higher performance by supporting
multiple outstanding commands.

If you don't know whether you have a UAS device, it is safe to
say 'Y' or 'M' here and the kernel will use the right driver.

If you compile this driver as a module, it will be named uas.
