hi all,
i have a problem with DS412+ as well. I was looking for adata c802 for a long time and finally i've found one on marketplace. But sadly pendrive was on different chipset than UT165.. bad luck... so i went again through all my old pendrives and i started looking for manufacturer's software for chipsets i've found in those pendrives. and i found one..
i've found a pendrive with controller: CBM2091, and I was able to change VID and PID with umptool209X V1.9.32_1107
tomorrow i'll transplant data from DOM to this pendrive - i hope that nas will start. but this is just a workaround. UT165 is ordered already- i'll replace it on DOM later on.
