I checked the VID and PID is written in the new_id file. In terminal: echo 04cc 0000 > /sys/bus/usb-serial/drivers/pl2303/new_idĥ. I found new_id file in the directory: /sys/bus/usb-serial/drivers/pl2303/new_idĤ. In terminal: modprobe pl2303 (It shows no error message)ģ. As root I put: blacklist acm in /etc/modprobe.d/acm_nf and /etc/modprobe.d/nfĢ. The commands didn't show any positive result. # I have connected the telescope in Windows8.1.

I'm using a raspberry pi to control a LED matrix display with a Prolific USB to serial cable (067b 2303).
