Power off a USB device
dissabte, 12/05/2012 (10:11) per carlesI wanted to power off a USB device. Searching in Google for “power off usb” returns different results but I didn’t succeed with any of the suggestions (Linux version 3.2.0).
I asked in the linux-usb mailing list (question, see one of the relevant answers (from Alan Stern). In short: not possible. Using a USB hub it’s then maybe possible -some models only-. The answer includes a link to a small program to try to disable the port. I could disable the port, but the device had still power.
