I applied this patch to use usbnsh config with flash file system.

*** Hangs up here ***

I found that it hangs up at smartfs_rename(), but I couldn't research more than that... The functions that uses smartfs_rename() may have same issue (only at this chip?).

@acassis Sorry, I haven't found a cause of this problem yet. This is just a issue report.

@takumiando can you try to duplicate it using for example stm32f4discovery board? Maybe it could be some missing configuration for rp2040 arch.

@acassis I resolved with this PR!
