When I run blinkstick --info I get the following message.

usb.core.USBError: [Errno 19] No such device (it may have been disconnected)

When I run dmesg I can see that my blinksticks are plugged in register in linux.

My system

Ubuntu 18.04
Python3.6
BlinkStick==1.1.8
pyusb==1.0.0b1

I am at a bit of a loss. is there another way of testing the devices. I cannot get to them via the command line or python.

A few things to try first:

  • try other USB ports. Is the port you are connecting is USB3?
  • try connecting through USB hub and see if you can control it that way

I’ll have a few other options when I get to the office tomorrow. Sorry about the trouble, I will get to the bottom of this!

I have two blinksticks plugged into this computer. Could that be the issue. I have run miltiple blinkstick devices off of my desktop before with no issue.

Okay, so the issue is my hardward. I am using these blinksticks with the Antsle virtual cloud devices and there is an issue with using their lcx instances and usb passthrough. If anyone has the same issue with Atnslle devices you can direct message me for my solution.
