problems with pysim-prog

Hi! I'm experiencing problems with pysim-prog. Using the example available in the README file. # ./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z lila -j 0 Insert card now (or CTRL-C to cancel) I get stuck here forever. The same message shows if I remove the supersim card from the reader. Running pysim inside strace shows: write(1, "Insert card now (or CTRL-C to cancel)\n", 38) = 38 ioctl(3, TIOCMBIS, [TIOCM_RTS]) = 0 select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout) ioctl(3, TCFLSH, 0) = 0 ioctl(3, TIOCMBIC, [TIOCM_RTS]) = 0 select(4, [3], [], [], {1, 0}) = 0 (Timeout) select(0, NULL, NULL, NULL, {0, 500000}) = 0 (Timeout) ioctl(3, TIOCMBIS, [TIOCM_RTS]) = 0 select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout) ioctl(3, TCFLSH, 0) = 0 ioctl(3, TIOCMBIC, [TIOCM_RTS]) = 0 ... [and so on] The pl2303 module is loaded correctly, and I have used it before to access some embedded devices via serial line: pl2303 2-2:1.0: pl2303 converter detected usb 2-2: pl2303 converter now attached to ttyUSB0 usb 2-2: USB disconnect, device number 11 pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 Any clue on what's wrong? Thanks!
