VMWare's shared CCID reader doesn't work

[mickflemm]

The behavior is a bit strange, it seems that some reads/writes succeed and others fail. For example pcsc_scan works and recognises the card but opensc doesn't work. Note that gnupg's scd internal ccid driver (https://github.com/mtigas/gnupg/blob/mtigas/scd/ccid-driver.c) works just fine so this is an issue with ccid and/or pcscd.

This is what I see in the logs: ifdwrapper.c:369:IFDStatusICC() Card not transacted: 612 eventhandler.c:333:EHStatusHandlerThread() Error communicating to: VMware Virtual USB CCID 00 00 ccid_usb.c:797:WriteUSB() write failed (2/4): -4 LIBUSB_ERROR_NO_DEVICE ccid_usb.c:836:ReadUSB() read failed (2/5): -7 LIBUSB_ERROR_TIMEOUT ifdwrapper.c:369:IFDStatusICC() Card not transacted: 612 eventhandler.c:333:EHStatusHandlerThread() Error communicating to: VMware Virtual USB CCID 00 00 ccid_usb.c:836:ReadUSB() read failed (2/5): -1 LIBUSB_ERROR_IO ifdwrapper.c:369:IFDStatusICC() Card not transacted: 612 eventhandler.c:333:EHStatusHandlerThread() Error communicating to: VMware Virtual USB CCID 00 00 ccid_usb.c:797:WriteUSB() write failed (2/5): -4 LIBUSB_ERROR_NO_DEVICE

Please let me know if you want me to test any patches or at least give me a hint on where to start debugging this.

Thanks for your time

These are errors reported by libusb. Please follow https://pcsclite.alioth.debian.org/ccid.html#support to generate logs with more details.

I attached the log as you said, below is the console output of the commands I issued. Note that I also recompiled gpg scd to use pcsc instead of the built-in ccid driver and it also fails so it's not due to card handling, it's something wrong with the reader driver.

Please let me know if I can help in any other way.

I can't find any error in your log file.

Maybe you should increase the debug level of opensc-tool.

[mickflemm]

Seems like it detects the card is present but then it doesn't respond.

I found the problem. It is a known vmware bug. See the comment in https://pcsclite.alioth.debian.org/ccid/unsupported.html#0x0E0F0x0004

This vmware reader is in the "Unsupported or partly supported CCID readers" list. I can't help. Report the problem to vmware.

[mickflemm]

But it works with Gnupg's built-in ccid driver and it also works on windows. Anyway I'll try to debug this further and if possible come back with a patch or something. Thanks for your help.

@mickflemm did you get anywhere with this issue? I get on average each 100th signature "The smart card has been reset, so any shared state information is invalid." on average every 1000th signature "Protocol not supported" I suspected Auto Power On Off (pcscd Compiler options) as the culprit. I'm using pcsclite 1.8.20 libccid 1.4.22 with Gemalto Twin CT40 and Cherry TC1100.
