It looks like the device descriptor wasn't read correctly. Without that
the kernel can't attach the device.
Did you try removing it and hot-plugging to see if it works?
If a USB device doesn't respond to configuration requests appropriately,
then it is usually because it is :
a - damaged
b - the hardware (pen drive) has a power issue
c - firmware is too slow on the device to respond.
Try a new pen drive.
You can certainly detect that a device you expect isn't mounted, not
sure how to tell udev to try to reconfigure it again after it failed the
first time around...
