ccid: Fix dwProtocols advertisement of T=0
Commitd7d218ef02
attempted to change dwProtocols to only advertise support for T=0 and not T=1. The change was incorrect as it changed 0x00000003 to 0x00010000. lsusb -v in a linux guest shows: "dwProtocols 65536 (Invalid values detected)", though the smart card could still be accessed. Windows 7 does not detect inserted smart cards and logs the the following Error in the Event Logs: Source: Smart Card Service Event ID: 610 Smart Card Reader 'QEMU QEMU USB CCID 0' rejected IOCTL SET_PROTOCOL: Incorrect function. If this error persists, your smart card or reader may not be functioning correctly Command Header: 03 00 00 00 Setting to 0x00000001 fixes the Windows issue.
