Hello,

I am new on this forum and have a problem with dualminer with PI.

When I connect the dualminer, then this will appear in the list with ls /dev/ttyUSB*, but cgminer does not find USB hardware.
After exiting cgminer also the dual miner has disappeared from the list.

The hub and dualminer work under Windows without problems.

Has an idea where the problem is?

Thanks.

Hi, epcoin

Did you use sudo to get required privilege for running cgminer? Would you please take a photo of your screen and post it here or forum.dualminer.com? Our engineer will track your issue closely.

Thanks.

Hi, dmsp

here are the screen printing

After the end cgminer no more /dev/ttyUSB* are available

You need more informations?

Thanks for help.

It seems problem related to usb bus power or usb driver from -D information. Please confirm the DIP switched to L mode and check your PM. We will help you to find the difference between your rig and CruzCoins'.

The DIP is switched to L and I use TeckNet HU10 10 Port USB 3.0 Hub. This hub looks exactly like orico p10-u2.
When I connect this HUB and dualminer to a Windows PC and run DualMiner (download from dualminer.com) is't run without problems.

Your problem most likely is that raspberry pi notoriously does not work well with usb 3.0 hubs. See this link for more information about compatible hubs with Pis: http://elinux.org/RPi_Powered_USB_Hubs I recommend using nothing above usb 2.0 when trying to mine with Raspberry Pi for now. Also please be aware of this from the above link:

..if the HUB tries to feed the Raspberry Pi through their interconnect cable, due to the 100 mA limiting fuse in the Raspberry Pi, the Raspberry Pi will be partially powered which may cause problems (unwanted writes to the SD card).
