kernel bug with USB s/w
« on: May 02, 2011, 03:41:13 AM »
Hi All,

I am trying to get TC to run on an eBox 3300MX PC with a Vortex SOC h/w core.
I frequently get errors for USB connections similar to the following

generic-usb: probe of 0003:0EEF:0001.0004 failed with error -32

What does this mean?

I think it might be a latent kernel bug that shows up with the non standard x86 core.

Peter.

You could try posting a question to the mailing list at http://www.linux-usb.org/

It could be a bug in linux code, or in your usb hardware (the chipset, or the stick).
The only barriers that can stop you are the ones you create yourself.

A quick google search seems to indicate the 2.6.29 kernel changed in a way that exposed bugs in some drivers. If you are knowledgeable enough, you can try to patch and recompile the affected module, using the example for the Saitek Cyborg Gold Joystick.

Thanks guys.

I am not experienced enough to be able to patch.

I have tried the same configuration on other h/w platforms and I get the same error message.

There must be a list somewhere that tells me what an error 32 means.

Is this for a particular device or for any device? If it's a particular device, then load the usb-utils extension, execute lsusb, and post the results. I expect that particular error could be caused by one of many different problems, but with additional information we may be able to see something.

Here is an lsusb -v output.
The error occurs repeatedly with my touch screen (which I have not been able to get to work. It does work fine under MS Windows).

Here is the dmesg output also. I thought it may help.

I can't offer ony suggestion yet, but when looking at USB related stuff I always find the output of lsusb -t quite helpful, plus the output of lsmod to know what kernel modules have been loaded. You might want to add those few lines here as well.
