Amazing, thankyou so much! I’ve been having USB issues for months, and this one script works to fix them all! Amazing, thankyou so much!

I have been looking for a solution for a once and then hanging built-in usb-hub for a very long time now and have finally found it here. Many thanks for the usbreset script!

I suggest looking for the relevant /sys/bus/ location on your device. The path should be quite similar.

I use 4 of them, vid 0x0483,pid 0x3748, the same on each of them. I can distinguisg them by commandline stm8flash -S serial number option. The only solution I think there is to power cycle each one separetly . Power cycling on usb hub doesn't work neither. Newest firmware loaded in to stlinks.

It saved me immense grief when all of my USB devices went dark on my Ubuntu 16.04 system with lots of unsaved work. Unplugging and replugging everything hadn't had any effect, and the system put up a dialog advising me I had files open and how did I want to restart that I couldn't dispatch because the mouse didn't work! I ssh'd in from a laptop, and your script brought my desktop back to life - WHEW!! Again, many thanks!! Happy New Year - 2020, "the year of perfect vision" Many thanks for your script!

It works wonder on uBuntu 16.04!!! However, when i tried on a Nano Jetson, which is a arm64 architecture, the directory /sys/bus/pci/drivers/?hci_hcd do not work as the USB file was not in it BUT i do found out the directory of the USB itself. By changing: '/sys/bus/pci/drivers/?hci_hcd' to '/sys/bus/usb/drivers/usb' and 'for i in ????:??:??.? ; do' to 'for i in usb? ; do' it works on both amd64 and arm64 now.
