Hello,

Now we know that the bug is located on reader side at USB stack level and not in
Linux and libusb.

Also we have closed the bug reports [1], [2], [3] and we have done bug reports
to the manufacturers involved.

Note that SPR532 is also concerned.

Solution:
==========
To solve the bug for the SCR331 upgrade the firmware with version 5.x.
I have tested it successfully with the firmware 5.13.

A new firmware for SCR335 is planed in July and a new for SPR532 is planed in
August.
We hope they will correct this bug.

For the ACR 38, send your request to Advanced Card Systems.

Yes "partly supported" is a good solution.
