Hello,
I was thinking to implement the cyberJack PIN pad reader support.
Unfortunately, I ran into a problem when I must reset the reader with
usb_reset(device_handle). However, I don't see ifd_device_ops.reset
implemented. Is there a way to cleanly invoke the USB device reset
functionality?
I attached the patch that I think is needed. It would be nice to
integrate it into the tree.
Thank you.
