power off the usb cause system crash

[mcdull]

I have built the uhubctl on a raspberry zero wh and would like to control a 7 port orico. I installed the latest libusb and build from master.

When issuing the command, some will response instantly, some may delay for 10 seconds, and sometime it will just crash. The image I use is raspbx, and should be quite similar to the original raspbain.

root@raspbx:~/uhubctl# apt-get upgrade libusb-1.0-0-dev

Are you trying to control internal hub or external one? Raspberry Pi Zero internal hub doesn't support proper power switching. As for external hubs, I'm not aware of Orico. Any hub from current supported devices should work.

Are you trying to control internal hub or external one?

As far as I recall the RPi Zeros are like the Model 'A' variants of their bigger brothers in that they do not have an internal hub - only a single USB port; the Model 'B' variants of the full-size RPs of course combine a 4 (2 on older models) USB 2.0 Hub which also contains the wired Ether-networking port so that also explains why the 'A's lack built-in wired network capabilities and why the Zero doesn't either.

Sorry, but I have not seen any response about details in more than 2 weeks. Feel free to reopen if you can provide more details about your crashes.
