I don't understand. Why would dummy_timer behave differently for the
second URB submission? It should follow the same logic and return
-EPROTO just like the first time.
To fix that, make sure the dummy_hcd is enabled at enqueue time to
avoid adding urb to the urbp list.

This is not the right approach. We want to allow URBs to be enqueued
even if the device's upstream port is not enabled. After all, real
HCDs allow this.
Yes, you are right. Just drop this patch. Sorry for the noise.
Cheers,
