Re: ACS ACR122U A9 issues

Hi,

Actually I receive this error when I run the mfcuk command. I am not touching or removing any card reader or card. As I said I tried the same in 2 different operation systems but in the same computer and I had the same issue.

Cheers,

vazma

According to the log,

[36m00000005 [0m [34mifdhandler.c:372:IFDHPolling()
usb:072f/2200:libudev:0:/dev/bus/usb/004/023 (lun: 0) 600000 ms [0m

[36m00000021 [0m ccid_usb.c:1794:InterruptRead() InterruptRead
(4/23): LIBUSB_TRANSFER_NO_DEVICE

It seems that the reader is removed during the operation.


This is a strange error code.

When the device is removed you should get LIBUSB_ERROR_NO_DEVICE but you get LIBUSB_ERROR_IO instead.

When libusb_bulk_transfer() returns LIBUSB_ERROR_NO_DEVICE the driver returns STATUS_NO_SUCH_DEVICE and the reader should be removed at the PC/SC level.

Your device (or your kernel USB stack) may be in a strange state.
