Binary package hint: tilp2
Tilp2 has severe problems with the Silver Link USB cable. After choosing
the right link cable and calculator, Tilp2 shows two errors as GUI
windows.
Error # 1
Msg: Failed to open USB device.
Cause: check your USB cable is plugged and /or the calculator is ON! Check your
libusb and usbfs permissions, too.
System: Operacion no permitida (errno = 1) -------- translated as : operation
not allowed
Error # 2
The cable can not be used.
Cause: the cable has not been initialized due to a previous/current error
My calculator is a TI V200, i'm using a silverlink cable. i had check
the permissions of libusb and is set in 644 to root:root. i can't find
the other file that is mentioned: usbfs. Trying to get more information
about this error, i opened tilp using a console/terminal. the result is
this:
