How to connect ColorSpace UDMA2 to computer?

Hello,

I read the instructions on
https://hypershop.zendesk.com/entries/39519747-How-to-connect-ColorSpace-UDMA-to-computer-
Obviously it refers to the former model ColorSpace UDMA.
I have the next generation UDMA2 :-)
After connecting to my computer (WinXP SP3) is shows the hyperdrive
and the name of the harddisk. (Mf HGST, model 27K500-500 HTE725050A7E630)
(Tested with USBdeview)
But no driveletter was assigned.
Even on my Android (V 4.4.2) tablet with an OTG-cable I had no response.
The orange LED on the drive was lit during both tries.
Must the USB-connection be enabled on the Hyperdrive and how ?
After a lot of Googling on the problem:
e.g. http://www.buzzillions.com/reviews/sanho-hyperdrive-colorspace-udma2-backup-storage-device-sata-casing-reviews#smoothScrollToSection
I gave up and ask:
Do you have a solution ?
Thanks for help.
