uhubctl works fine with 1 rpi4, but not with another four

All 5 RPI's have the usb device plugged into the same USB port

Any ideas? Many thanks

Well, If I run it w/o the usb device inserted (Netgear nighthawk USB3 6ghz stick) it seems to work fine. Strange that it works with one nighthawk and not the other 4

I may have resolved with the -p 100 flag, will test overnight

[mvp]

You probably meant -r 100 flag? Note that this flag should not be needed if you upgrade your OS to use Linux kernel 6.x.

Another question: which version of uhubctl you are using? It must be 2.4.0 or higher to work properly on RPi4B. Preferably latest version 2.5.0.

[trentbrown13]

Thank you mvp

no, I was using -p, I will try -r tomorrow. my linux kernel is 6.1.21-v8+ and my uhubctl version is pi@HalleBerryPi:~/bin/TEST $ uhubctl --version 2.5.0-1

I am still seeing issues but not as bad as before. Thank you for the response!

[mvp]

-r should not be needed under kernel 6.x, because uhubctl would use different method to turn power off, one that Linux kernel should specifically support since kernel 6.0. Perhaps some of your RPi4B instances were using kernel 5.x? That would explain small difference in their behavior.

Anyway, I am closing this since you seem to have a solution.

[trentbrown13]

Sorry for the late response. I checked and all my RPI4B's are using the 6.0 kernel and -r vs -p did not seem to make any difference.

That said, I don't think this is an issue with your code, likely more of an issue with the device as if I leave the device in the RPI4B but not doing anything it crashes on its own after some time.

I'll try another manufacture using the same Mediateck chip to see if there is a difference. Thanks!
