I have Raspberry Pi 0 W, attached to this I have a CANBUS USB Module:
https://www.aliexpress.com/item/1005006 ... 1802q2vTUK
I connect to the Raspberry Pi using SSH on my iMAC and type:In the console, if I then type:I can see 4: can0. The problem I am having is that if I then execute:Then allow time for the Pi to reboot and boot up again then:Then:Now there is no can0 present, if I unplug and then reconnect the USB device, it reappears, what can I do to resolve this issue so can0 always reappears in the list after a reboot ?
Is there a way to re-initialise a USB scan as if a device was freshly plugged in, something I can execute on boot ?
