Connecting multiple PRoC CYSmart USB Dongles in Linux

[Anonymous]

I am trying to connect multiple PRoC CYSmart USB Dongles to linux (Raspberry PI Model 3). The first dongle I connect successfully shows up as a ttyACM0 device, but if I connect another dongle, it fails to show up as ttyACM1 as per expectation. Both the dongles connect and successfuly create hidraw* under /dev/ but only one is allowed /dev/ttyACM0, can someone with linux experience please comment on this?

It seems like the linux is setup to only enumerate/utilize one at a time. Try reading this post and seeing if you can implment a similar method to get it to work: http://docs.brewpi.com/en/latest/advanced-setups/multiple-arduinos-single-rpi.html

   

Most likely, it isn't a hardware restriction, but rather a setup/configuration to properly use and interaface with two dongles.

   

I don't know much about linux, but one step at a time 🙂
