I’d like to add that in my case, the issue was Linux not allocating enough memory to USB devices.
As soon as I enabled the VSG60A while the BB60C was running, the application would either crash or disconnect one or both devices.
https://solutionspagedemo.kinsta.cloud/sigdownloads/SDK/online_docs/vsg60_api/index.html contains instructions on how to solve:
sudo sh -c ‘echo 32 > /sys/module/usbcore/parameters/usbfs_memory_mb’
Additionally, here’s how to make these new settings persist at boot:
Create a file: /etc/modprobe.d/signalhound_usb.conf
Containing:
# 16mb per signalhound device is needed, we set 3x that value here to have some head-room
options usbcore usbfs_memory_mb=48
Next reboot, this will automatically be applied!
