iXpand 128gb "Error failed to connect to iXpand drive. please remove and reattach."

iXpand 128gb “Error failed to connect to iXpand drive. please remove and reattach.” connecting to iphone 7 ios 10.1.1

have re-flashed using the HPUSBDisk program, running lastest app version 4.2.1 as of 12.8, have updated using 2.0 update tool

and device firmware 2.60.103.0 

…???

if you have FW version 2.60.103.0  you have an iXpand UBS 3.0. you are a few FW version behind. the current is 2.60.103.80. try using the update tool linked below for the iXpand USB 3.0. If it still fails to connect it may need to be replaced.
