In FSL WindowsBSP,
We have the problem that a CPU may be hung-up, when a register is written by USB Driver.
When a USB driver writes any value into offset 0x017C of HS-USB register, this problem may occur.
In the source code of WinCE BSP, this register is defined as ENDPTNAKEN.
However, in a reference manual, this 0x017C register is "reserved".

- Table 60-28. HS-USB Register Summary(P.2882)
In Linux BSP source code, this 0x017C register is not defined.
What kind of function does this 0x017C register have?
Is access(writing) to this 0x017C register required?
