Feedback and bug for USB HDD installation (libusbhsfs)

[ghost]

Some feedback for the new USB HDD installation feature (Atmosphere 0.15.0 without fsp-usb running, Firmware 10.2.0):

• Games install correctly but after exiting DBI you can get an error
• After installing any game from USB HDD if you exit and open DBI again you will get a black screen and you are unable to open DBI again until you reboot the Switch
• The installation speed seems slower, around 33% - 50% of what it was with fsp-usb (I used the same exFAT USB HDD to test)

How do you launch DBI? Applet (albums) or title (game) mod?

And did you tests installation with the same game to the same place?

I tested both and it was the same for both.

And did you tests installation with the same game to the same place?

I tested two games both in AUTO mode.

Try with latest version please. It built with newest version of libusbhsfs

Tested (firmware 11.0.0 and atmosphere 0.16.0 second prerelease, DBI 201):

• Speed is a lot faster, looks the same as fsp-usb or maybe a bit faster

• There are still some errors after installing games from USB drive. For example this is what happened:

1. Install game from USB0, the game installs correctly
2. Exit DBI and receive error (Nintendo error, asking to share or do not share error report)
3. Open DBI again, it works
4. Install another game from USB0, the game installs correctly
5. Exit DBI, no error
6. Open DBI, black screen. Need to reboot to access DBI again.

DBI 202: USB drive not detected at all in DBI

Since 202 libusbhsfs is opt-in: to use it create /switch/dbi.libusbhsfs flag file.

Also, make sure you are using dbi in applet mode.

Ok thanks, is that for hiding the option while it's under development?

Anyway I just tried it and USB0 is not appearing with DBI.nro + dbi.libusbhsfs flag file in either /switch/ or /switch/DBI/ (I usually use folder)

It appears fine in 201.

Try with new 204 version

Try with new 204 version

The flag works now. DBI has a black background in application mode now, intentional?

Atmosphere 0.16.0 prerelease 2, DBI 204, tested firmware 10.2.0 and 11.0.0, both same result:

• Application mode: install, exit, open DBI, result- black screen

• Applet mode: install, exit, open DBI, result- Atmosphere error https://gist.github.com/FlyingBananaTree/21675bfb212ecaf95e66b3b4a6dbf501

Did you tried the same scenario with libusbhsfs example application?

Black bg is intentional. DBI not designed to be run in application mode.

Black bg is intentional. DBI not designed to be run in application mode.

I checked, it seems that the example application can also trigger this bug. I'll open an issue there.

By the way I've never had an issue with DBI in application mode, unless you mean it can specifically cause issues with libusbhsfs.

@duckbill007 It was a libusbhsfs issue.

Should be fixed in: DarkMatterCore/libusbhsfs@ae8663d

Confirmed fixed in DBI 206, thanks!
