I suspect a bug in the USB hardware or USB Linux layer of your arm platform
then.

I just talked to a USB expert and the reader (USB device) has no idea of
the reception buffer size. So the problem should not be in the reader (for
this bug).

Without your change you have a working reader and a non working one?

Using the same hardware and software platform?

Try to upgrade to a recent Linux kernel.
Are you using Linux?
