Hello fellow Tumbleweed users.

I noticed a strange phenmenon with charging my Sony phone on this Tumbleweed workstation - it does not charge in multi-user.target, or VT, or display-manager. It only charges after I have logged into desktop. Does anyone know how to alter the behaviour so that Linux will allow it to charge as long as the system is powered up?

Thanks.

-----Ursprüngliche Nachricht Ende----- This is not only a problem of Tumbleweed but of all installations and does AFAIK more depend on the BIOS setting.

Two solutions come to my mind: a) you set the "usb-legacy" support to "on" in the BIOS. That should power up USB even if the desktop is not logged in. b) you use a dedicated usb plug (some of the machines have a special plug that charges even if no OS has been started up). Maybe that has also to do with PAM as the Sony will probably charge when recognized as a usb-key or token. For security reasons it is possible that the PAM setting does not allow to mount such devices (mass storage) but only after the authorized user logged in. However I do not know sufficiently about PAM to tell with certainty. --- Alle Postfächer an einem Ort.

On the bios of my last desktop (ASUS Motherboard) I found that by enabling wake on USB I was able to charge my my phone even when the PC was off.

Good tip, but I cannot solve an issue that arises while the host is active. Regards Oliver -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Hello! Thanks for your hints. I suspected that power management is the curlpit, and it turned out that "autosuspend" is the magical parameter. By writing -1 into /sys/module/usbcore/parameters/autosuspend, the USB port remains powered non-stopping. Regards, Howard On Wed, 13 Apr 2016, Oliver Neukum wrote:

So..what is the USB id of this device.. so we can figure out what is enabling autosuspend for this particular device (it isn't/wasn't enabled by default last time I checked) and udev rules to enable usb autospend by default were rejected with EKERNELPROBLEM :-) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

We would want it to be autosuspend while we are operating on battery though. Simply removing the rule wonŽt do the job. Regards Oliver -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Thank you Simon! By turning on USB wake support, the phone begins charging as soon as the system is powered on, where previously it would only charge in desktop. However, it still stops charging during the Linux boot process, and would only resume when I'm in desktop. The year of Linux desktop will come eventually..
