Tonight I tried to control my telescope, a MEADE LX-90 with KSTARS using INDi-Lib 0.9.8. The telescope is connected to a PC using an USB-serial-converter (/dev/ttyUSB0).
Under Ubuntu 10.04 I am able to connect and to control the telescope, but with Ubuntu 12.04 I cannot connect to the telescope. I also tried a Raspberry Pi and it worked.
