Logitech v20 USB Notebook Speakers

Postby whatsvictory on Wed Sep 24, 2008 3:18 pm

I have a set of Logitech v20 USB Notebook Speakers & I use the Mint XFCE final desktop. The problem is that my speakers won't put out any sound except for when I first plug them in I get the conformation sound built into the speakers themselves. I have changed the settings on the volume control on my panel but still nothing. The speaker built into my laptop are working fine. In the Gnome edition they worked right out of the box. In the Device Manager it says "Insufficient power to operate USB device."

Does anyone have any ideas?

Linux Mint is funded by ads and donations.

We'll have to check this out
Someone else noted that charging a cell phone from USB in Elyssa XFCE takes ages
At that time I tried to find something but did not
I'll ask the team and perhaps this is a bug that can be fixed. But please note that 2.5 W is max from a USB port. It's 5 volts and max 500 mA

Don't fix it if it ain't broken, don't break it if you can't fix it

This would be a kernel problem or a module problem.
Linux does not handle powering down/up USB devices all that well.
an application may load a specific module to better handle the power requirements of a device.
otherwise if the kernel does not know exactly what device has been connected it may take the safe option an use a low power generic device, maybe like a keyboard.
USB 2.5inch HDD need a max of 520mA so they need 2 USB dongles for power (only one is data).
another possibility is it is the device (phone or speakers) being safe since it is the device that draws power, it is not pushed in. this could still be kernel related as the phone needs some signal to draw max power (amps).

I don't have usb speakers but tried other usb devices on my wife's laptop.
For some reason it was loading the usb ports as 1.1 instead of 2.0.
It would also say "Insufficient power to operate USB device."

So I loaded up Linux Mint 5 Main(Gnome) and it loaded the ports as 1.1 instead of 2.0.
Not sure but I thought the ports where 2.0.(will look into this later)
Gnome at 1st didn't say "Insufficient power to operate USB device.", but after a few times of reconnecting, it would say it.
Seems like both have this problem just Gnome doesn't have it as often.
