With certain hardware combinations the poll interval is exceeded before

I was unable to reproduce this issue using other hardware combinations.
I thought it might be a USB3 issue but another laptop with USB3 worked
without the patch.
With my hardware the polling count reaches around 230 before
initialization completes.

If the adapter initializes quickly, this change causes no problem. I have not
seen this kind of problem, but some hardware is obviously different.
