Some tests where the ESP (acting as host) will require that a particular test
|
|
device acting as a MSC SCSI flash drive be connected. That test device's
|
|
information and descriptors are defined in this file.
|
|
|
|
If you are connecting a different MSC SCSI flash drive, please update
|
|
the descriptor and getter functions accordingly.
