[Bug] USB exception: [Errno 16] Resource busy

[DreamDevourer]

When connecting the USB-C with tinfoil opened in the Switch error 16 shows up:

USB Connected
usb exception: [Errno 16] Resource busy

To Reproduce

Steps to reproduce the behaviour:

1. Open Tinfoil in the gallery or using "R" in a game with full Horizon memory use
2. Connect USB-C to the PC (in this case Debian-based distro Linux)
3. Open NUT_GUI.py
4. Observe the error happening in the terminal and Tinfoil crashing.

Expected behaviour

Switch should connect without problems in NUT.

NUT version (or git hash):

• Nut: [e.g. v3.0]

@DreamDevourer have you tried this (from the Readme):

(Linux only) Add the following code snippet to /etc/udev/rules.d/99-switch.rules using your favorite editor.

SUBSYSTEM=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="27e2", GROUP="plugdev"

[DreamDevourer]

Yes, it's there. Also I tried to install the requirements_dev with pip3, but did not work for some reason.

[DreamDevourer]

All the dependencies are already installed.

@DreamDevourer what's switch OS version? tinfoil version?

[introkun]

Have you tried rebooting Switch? Have you tried to unplug/plug the cable?

[introkun]

@DreamDevourer could you please try my code from the PR #288 ?

[DreamDevourer]

I did not disconnected the USB cable, also I tried using Quark from Goldleaf project and that worked pretty well... But I want to use Nut it's much better for what I want.

Switch Horizon version: 10.0.4
Using atmosphere 17.0|S
Tinfoil (LITHIUM) from this repo Blawar Version 11.00

[introkun]

@DreamDevourer any luck with my PR?

@DreamDevourer can you try disabling MTP in tinfoil options, then restarting Tinfoil and try.

I'm having the same issue here. It's happening after upgrading Switch firmware from 10.0.3 to 11.0.0 and Tinfoil from release 8 to release 12. Running Ubuntu 20.04 LTS, Switch firmware 11.0.0 with SXOS 3.1.0 and NUT 3.1, all python3 dependencies updated.

Also, on Windows machine, using NUT 3.1, I'm able to connect to the Switch but NSP files shows as "0.0 B" and when I try to install them, an error message pops up saying that there's an error when trying to open the NSP file, although the files are OK.

Can you try installing it via usbfs instead of usb, and see if that works?

I am having this same problem. I tried using the code from PR #288 as suggested by @introkun... It didn't help. However, disabling MTP has stopped the crash, but I still could not access the files on the computer (errno 13 access denied insufficient permissions). After running nut as sudo in a python virtual environment, I was able to get it to work. I hope this can help someone else.

I'm running the latest version of nut and tinfoil, ubuntu 20.04, 12.0.2 switch firmware, and atmosphere 0.19.3.

I actually got around this issue. I'm using Lithium instead of Tinfoil, but it looks like the Switch changes device IDs during the connection process. I had to duplicate the udev rule for 057e:2000 and 16c0:27e2. Also, Arch (and Arch-based) distros do not have a plugdev group, so I changed the group to wheel instead, but you can use any arbitrary group your user is a member of.

So /etc/udev/rules.d/99-switch.conf file looks like this.

SUBSYSTEM=="usb", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="3000", GROUP="wheel"
SUBSYSTEM=="usb", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="2000", GROUP="wheel"
SUBSYSTEM=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="27e2", GROUP="wheel"

Don't forget to reload the rules (udevadm control --reload) to make them take effect. It works fine with MTP disabled.
