Thats strange. Perhaps you need a firmware-update as mentioned.

What operating system do you use? What is the software version of
avrdude. I use avrdude: Version 5.11.1, it runs on linux, kernel
3.5.0-38 with no problems. Of course, you have to put the information
for usbasp (16c0:05dc) to /etc/udev/rules.d

Try to set the speed parameter (i. e. "-B 50") to slow down the
communication. What does avrdude show, when you call it with parameter
-v instead of your own program:

avrdude -p t2313 -c usbasp -B 50 -v &> dude.txt
