Hi all,

I am trying to fix a usb problem on a single board computer with a VIA chipset. Plugging in a high/full speed usb device hangs the machine, while a low speed device (a usb mouse) works fine. I'm using kgdb to see what's going on, but stepping too far through code changes the behaviour. How do you go about getting to the real problem?

If it helps, after finding the new device it seems to go from the usb_set_address() call in usb_new_device() to as far as hcd_submit_urb(), but never returns to usb_new_device().

Thanks for your help,
Malcolm.
