Ok with pi 1 B but not anymore with pi 4 B #84

Closed gortador closed 2 years ago

gortador commented 2 years ago

Hello, I realized that the relay was detected by lsusb in the raspberry pi 1 B but was no longer detected with the pi 4 B, however both are up to date, could you tell me how I can make it recognize? what libraries or manipulatio to do please

wentasah commented 2 years ago

lsusb does not rely on any library related to relays. If the Linux kernel sees the relay, lsusb should show it. If not, it is usually a hardware (cable) problem. Do you see some suspicious messages in the dmesg output? Usually something like "usb enumeration failed" or "usb device timeout".

I see absolutely nothing, as if the relay was not connected, on the other hand it appears well on my pi 1 B so it works and is recognized but not on my pi 4 B

Does any other USB device work (is visible in lsusb) on 4B? dmesg should show at least something like:

usb 2-3: new SuperSpeed USB device number 10 using xhci_hcd
gortador commented 2 years ago

yes all my other peripherals work, and this even if I change the sockets, the relay is not displayed anywhere of the 4 usb ports of the pi4, but is clearly visible on all the ports of the pi1

That's strange. I've never seen this. When connecting a relay to my Pi 4 B, I see this:

lsusb shows this:

I guess you've already tried different cables.

No response, I assume new cables fixed it.
