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.
