SKR 2 USB MSC

[dotdash32]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

Based on #17222, it would seem that SDIO MSC/CDC composite support is availabe for STM32 boards. Based on the example in [env:STM32F407VE_black], I tried to copy the environment for the SKR 2 (STM32F407VGT6).

However, it's not working my the simple 512mb card. Will follow up with testing larger SD cards, but it usually seems that smaller cards are better?

Expected behavior

2 USB devices become available on the computer, one for CDC serial and one MSC mass storage.

Actual behavior

Only the CDC device appears.

Steps to Reproduce

1. Set SKR 2 as mainboard
2. create "USB" env with additional build flags

# add USB??
[env:BIGTREE_SKR_2_USB]
extends             = env:BIGTREE_SKR_2
platform            = ${common_stm32.platform}
platform_packages   = ${stm_flash_drive.platform_packages} 
build_unflags       = ${common_stm32.build_unflags} 
  ; -DUSBD_USE_CDC
build_flags         = ${env:BIGTREE_SKR_2.build_flags} ${stm_flash_drive.build_flags}
  -DUSBCON
  -DUSBD_USE_CDC_COMPOSITE
  -DUSE_USB_FS

Will ask on Discord, but based on issues on SKR2 github, it is not supported. If it is, I will report this back.

[dotdash32]

Bumping this. Asked in Discord, and according to this from @rhapsodyv, there are still some changes pending. There are others who are experiencing the same thing in #bug-reports without any feedback from BTT.

Can this be reopened until these changes have been fixed? Or at least hear a little more about what the missing issues are?
