The USB driver framework only implements a single ISOC transfer.
If multiple transfers are needed, the class driver can initiate
multiple urbs to meet the real-time requirements of the ISOC
endpoint. The class driver's urb record the buf address, length,
and number of packets sent. The callback function calculates the
data location in the buf based on the callback number and length
returned.

Many times, context switching does not occur when the thread stack
memory is almost exhausted, so we need to mofify up_check_tcbstack to
accurately detect it.

Sim use coroutine base on one thread in host to do switch context. but if we allow switch context with in one API (host-API and errno get), maybe the switch context from coroutine cause re-enter host-API call. Make the errno get behavior not work as expected.
