Todd,
Do you have pcsc-lite built with libusb support? hotplug_linux.c is
entirely surrounded with:
#if defined(__linux__) && !defined(HAVE_LIBUSB)
...
#endif /* __linux__ && !HAVE_LIBUSB */
So if you have libusb support enabled, that code shouldn't be used.
PCSC/src/hotplug_libusb.c now (in the subversion version only) has:
void HPEstablishUSBNotifications(void)
{
/* libusb default is /dev/bus/usb but the devices are not yet visible there
* when a hotplug is requested */
setenv("USB_DEVFS_PATH", "/proc/bus/usb", 0);
usb_init();
[...]
The default value of USB_DEVFS_PATH is /dev/bus/usb but that does not
work with udev hotplug feature. It looks like the USB devices appear
in "/proc/bus/usb" before they are also available in "/dev/bus/usb".
Read the thread [1] for more info.
Using "/proc/bus/usb" may not be a so good idea :-(
Bye,
