What causes "USB disconnect" ?

[Frédéric L. W. Meunier]

I never got this messages since I started using 2.6. Today I 
got it in 2.6.16-rc2. Is this a problem in this version ? How 
to determine ? I wasn't using the device.

The device went away.

10 minutes later it came back.

Did you bump the cable?

It it still working ok?

Did it go into "suspend" mode and just power down, and then later come
back when you touch it (like a mouse)?

thanks,

No.

I think so. I don't do any gaming actually, but tested with jstest and
all buttons are working.

When it happened, his lights turned off. I pressed a button, but
nothing happened. Then, I ignored it and it returned after the minutes
you see from the log.

It happened again. This, after an uptime of 3 days and a few hours.

I changed it to other 2 ports and only see a

Any way to know if this is the device's fault ?

I just saw this behavior on a USB keyboard/mouse combo the other day when I 
touched the case and discharged static electricity.  Nothing else was 
affected, but I saw the keyboard and mouse disconnect and then immediately 
reconnect.  Possibly an intolerant chipset or poorly grounded motherboard?

I think it just died. I also have an USB mouse which is working 
fine, but I rebooted under 2.6.15 to see if the gamepad would 
return to live and it didn't.

About the motherboard, it's an ECS K7VTA 5.0 which I bought 
almost 3 years ago. Poorly grounded, probably, but not worse 
than it was before.

I've never seen it to be anything but the device's fault, as it's pretty
much impossible for the kernel to disconnect a device like this from the
bus without specifically sending a command to do so (and that didn't
happen here.)

So I'd blame your device :)
