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 two 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 =)

What operating system are you running?
If running Windows, did you use Zadig to install the USB driver?
Are you using CGMiner that was modified by VH to recognize the Gekko hardware?
If Raspberry PI running Raspbian, did you run the following?:

Code:

sudo apt-get update
sudo apt-get upgrade -y

sudo apt-get install -y build-essential git libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev screen libtool automake pkg-config libjansson-dev

mkdir -p git/vthoang; cd git/vthoang
git clone -b r606 https://github.com/vthoang/cgminer.git
cd cgminer

CFLAGS="-O2" ./autogen.sh --enable-gekko
make -j 2
