So would I. I'm not a usb expert. Someone suggested that umass.c
was not waiting for the device to power up completely, which makes sense.
The question is... how do you tell? Nobody's been able to answer that
question yet. I think -stable might have worked only as a fluke... the
latency between the kernel and the userland usbd providing the extra
time. In current the usbd equivalent is a kernel thread.
