Thank you. I've committed something similar. But it still does not work. Please notice that the reset is before any other command... Here is a normal sequence, you can notice that I get a responce from the GetSlotStatus message. --- Debug: ifd_open: trying to open c...@usb:/dev/bus/usb/002/033 Debug: ifd_usb_control: usb req type=x80 req=x06 val=x0100 ind=x0000 len=18 Debug: ifd_usb_control: recv 12 01 10 01 00 00 00 08 c3 0d 04 10 05 05 01 02 00 01 Debug: ifd_usb_control: usb req type=x80 req=x06 val=x0200 ind=x0000 len=8 Debug: ifd_usb_control: recv 09 02 5d 00 01 01 06 a0 Debug: ifd_usb_control: usb req type=x80 req=x06 val=x0200 ind=x0000 len=93 Debug: ifd_usb_control: recv 09 02 5d 00 01 01 06 a0 32 09 04 00 00 03 0b 00 00 04 36 21 10 01 00 07 03 00 00 00 a0 0f 00 00 a0 0f 00 00 00 00 2a 00 00 15 16 05 00 00 fc 00 00 00 00 00 00 00 00 00 00 00 30 03 01 00 0f 01 00 00 00 00 00 00 00 01 07 05 81 03 08 00 ff 07 05 02 02 40 00 00 07 05 82 02 40 00 00 Debug: skipped 1 class/vendor specific interface descriptors Debug: usb_set_params: called. config xffffffff ifc x00 eps x02/x82 Debug: ccid_open_usb: USB reset workaround Debug: ccid_open_usb: Accepted 0dc3:1004 with features 0x10330 and protocols 0x3 events=1 Debug: ccid_activate: called.

I need to run ifdhandler several times in order to reproduce this. But somehow magically the usb reset makes the device communicate correctly. Isn't there any CCID something to reset the device at application level?
