Ah OK. It's not entirely clear from the spec of my reader whether it supports
the CCID specification, although it does say it supports the T=1 protocol.

Not all that much more, I'm afraid. :)
$ gpg --debug-ccid-driver --card-status
gpg: DBG: ccid-driver: no CCID reader with number 0
gpg: pcsc_establish_context failed: no service (0x8010001d)
gpg: card reader not available
gpg: OpenPGP card not available: general error
Running the command through an strace shows gpg trying to access device nodes
directly (e.g. /dev/bus/usb/002/022) rather than entries in /proc/bus/usb as
the HOWTO talks about. The device nodes are, by default, writeable only by
root. But even with tweaked permissions and group ownership on the device
node, the same error occurs. The difference is that instead of reporting
"Permission denied" on the device node, strace shows:
open("/dev/bus/usb/002/022", O_RDWR) = 3
ioctl(3, USBDEVFS_IOCTL, 0xbfe8ad20) = -1 ENOTTY (Inappropriate ioctl for
device)
If there are any more suggestions of what I can try, I'm all ears. :)
Thanks,
Tony
