My networking / wifi connection drops occasionally (but not w/ other home computers) and the standard service start/restart instructions to network manager do not revive the connection. Would the same logic in usbreset work to bring back my wireless adapter? Here is a line from lspci: 03:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01) and here is the contents of the driver ath9k: 0000:03:00.0 bind module new_id remove_id uevent unbind Thanks in advance...

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.
