I didn't see that. I think I _do_ have CONFIG_USB_BANDWIDTH enabled. What
else do you have connected and what else were you using at the time? Does

I got hiccoughs while I was running with full debugging and a serial
console, unsurprisingly :)
I also get hiccoughs if I try to read /proc/bus/usb/devices while the
scanner is plugged in.
