Hi Johan,

I asked MOXA about this double opening. I also noticed that the
mainline driver ti_usb_3410_5052 uses the same double opening pattern.
And, MOXA UPORT 11x0 serie is based on TUSB3410 chip of TI.

So, I also emailed TI, and the authors of ti_usb_3410_5052 driver.

I keep you informed,

Thank you

Mathieu
