Songbird is a funny one. It's a web browser based on the Mozilla codebase, so its look and feel are completely different from the traditional music player. The main panel shows your music collection, you choose the media source from the panel on the left, and the control buttons are along the top. So far, so ordinary, but the main panel is actually a cunningly-disguised browser window!

So...when there is no activity...the usb device will be sent to autosuspend. At least I know kernel has this option.

Probably that can be disabled with appropriate command or boot time kernel parameter. I am in no need of it....so I wont immediately try to find solution...but I believe the net could offer it.

For example, the usbcore module accepts the parameter blinkenlights to display flashing lights on all supported USB 2.0 hubs (don't ever say the kernel developers don't have a sense of humor). To set this parameter when loading the module dynamically, you would enter:

$
modprobe usbcore blinkenlights=1

But if the usbcore module is built into the kernel, you achieve the same effect by invoking the kernel with the following option:

usbcore.blinkenlights=1

Most module options for modules that are built into the kernel can also be changed at run time by writing to files in the subdirectory named after the module under the /sys/module/ directory. Thus, the blinkenlights option is represented by the file /sys/module/usbcore/blinkenlights. desired.

Changing the default idle-delay time
173 ------------------------------------
174
175 The default autosuspend idle-delay time (in seconds) is controlled by
176 a module parameter in usbcore. You can specify the value when usbcore
177 is loaded. For example, to set it to 5 seconds instead of 2 you would
178 do:
179
180 modprobe usbcore autosuspend=5
181
182 Equivalently, you could add to /etc/modprobe.conf a line saying:
183
184 options usbcore autosuspend=5
185
186 Some distributions load the usbcore module very early during the boot
187 process, by means of a program or script running from an initramfs
188 image. To alter the parameter value you would have to rebuild that
189 image.
190
191 If usbcore is compiled into the kernel rather than built as a loadable
192 module, you can add
193
194 usbcore.autosuspend=5
195
196 to the kernel's boot command line.
197
198 Finally, the parameter value can be changed while the system is
199 running. If you do:
200
201 echo 5 >/sys/module/usbcore/parameters/autosuspend
And.........
207 Setting the initial default idle-delay to -1 will prevent any
208 autosuspend of any USB device. This is a simple alternative to
209 disabling CONFIG_USB_SUSPEND and rebuilding the kernel, and it has the
210 added benefit of allowing you to enable autosuspend for selected
211 devices.
