Re: [libusb] Invalid Maxpacket 64 bits

Hello,
I have a similar problem on my Debian GNU/Linux 4.6.0-1-amd64.
dmesg reports:

The problem is not just the kernel "warnings". I also get transfer issues.
For example libusb_bulk_transfer() returns only the first 64 bytes of
data when I am expecting much more.
The USB device is from Broadcom with 2 smart cards interfaces (and
other interfaces) internal in a Dell laptop E5570.
Is the USB device buggy?
Is it possible to make the communication work?
