Hello Guys, Ive got the same problem as "bmoscato" in his post number #1739, the final lines when running the make command are the same.
I read that he managed to solve that issue by unplugging his usb fan. I dont use a fan but the newpac miners are still not recognized by the cgminer.

-I have a 2 NewPac Miners in a Sipolar 10 Port USB 2.0 Hub 5V 20 Amp
-Raspberry Pi 4 B 4GB running Raspberry OS Buster ARM64 bit
-Followed the pinned procedure for debian/RPi installation

Tried on USB 2.0 as well as 3.0 --> No difference
Tried compiling with plugged in miners and with unplugged --> No difference
Checked USB Hub with miners on windows laptop --> no problems at all

Any help appreciated =)
