This one works okay as far as I can tell
Clock
Shows a popup and gives a console warning, but doesn't crash the program
Msg: timeout occured while reading to the device.
Cause: check that link cable is plugged and/or the calculator is ready.
System: Resource temporarily unavailable (errno = 11)
(tilp:18547): ticables-WARNING **: usb_bulk_read (No error).
EDIT: I was able to successfully back up the calculator and dump the ROM with a Silver Link cable.
