New Revision: 7024
Modified:
trunk/Drivers/ccid/src/ccid_usb.c
Log:
Ignore errno and use libusb returned value only
Checking (ENODEV == errno) should always be redundant with
checking (LIBUSB_ERROR_NO_DEVICE == rv)
Since errno is not a documented way to deal with libusb errors we will
ignore errno now.
Thanks to Hendrik Donner for the patch
