"libusb_open() returned NULL." on Arch Linux
elisaado opened this issue · comments
Hi, when I run xfer9860 I get the error:
sudo xfer9860 -i
--- xfer9860 v0.2.2 Copyright (C) 2007-2014 Andreas Bertheussen, Manuel Naranjo and Bruno L. Alata..
[>] Setting up USB connection..
ERR: libusb_open() returned NULL.
[E] A listening device could not be found.
Make sure it is receiving; press [ON], [MENU], [sin], [F2]
Is this still a problem?
let me check
Hey @sanjay900 thank you for your reply. The libusb_open() call works (I think), but the program segfaults now (see image below).
I just made a change, it should now tell you a device was not detected, instead of seg faulting. Test your cables, it sounds like the calculator isn't being detected correctly. Could you post the output of dmesg when you plug the calculator in?
Will check soon!
Hey @sanjay900, when I plug the calculator in (fx cg 50) and put it in receiving mode, I get
eli@probook ~/xfer9860 (git)-[master] % ./xfer9860 -d a a

[E] A listening device could not be found.
Make sure it is receiving; press [ON], [MENU], [sin], [F2]
so it does not segfault any more
Could you give me the output of dmesg when you plug in your calculator? The app just isn't detecting your calculator at all.
Also, which calculator do you have?
Hey @sanjay900, this is what dmesg outputs:

There are errors, but I can transmit and receive files just fine using Nautilus (from GNOME)
I have the Casio FX cg-50 (able to run all prizmSDK add-ons)
Oh, this software is not compatible with that calculator. Its only compatible with the FX-9860 / FX-9750
Ah, I see. Thank you anyway!
If you ever need help reverse engineering this device, just ping me :-)
