Obviously my post was partly misleading.
Did you check the creation ob the block devices in the phone's normal operation mode or in recovery mode? I didn't connect the phone to my desktop PC because on Windows 10 the MTP drivers got seriously destroyed so the phone was not recognized any more. I did the 'ls /dev/block' in recovery mode (TWRP) on the phone's terminal. It's provided by TWRP.

I would use lsusb and lspci.By that I meant that if it was a Desktop PC related problem, then I would type 'lsusb' there. Since it is an Android problem I did this check on my phone's terminal. And there (on the phone) only the USB port was listed. I think, that the SOC design doesn't require the phone's card reader to be connected to USB. I hope that made my idea more clear - although it led to nothing.
