drivers: USB MSC: STM32U585: can't pass Compliance Test by using USB3CV

[testo-jeff]

Describe the bug

USB MSC test failed when using test tool USB3CV, below is the screenshot:

Per debug, Zephyr can receive command A8 and 9E from USB3CV, and Zephyr USB protocol layer has handled the command, but in low layer(probably ST driver? not sure) can't send out the response to USB3CV, lead to test failed(100% reproduced).

Regression

• This is a regression.

Steps to reproduce

Configurations:
CONFIG_USB_DEVICE_STACK_NEXT=y
CONFIG_USB_MASS_STORAGE=y
CONFIG_MAIN_STACK_SIZE=2048
CONFIG_USBD_PID=0x0045
CONFIG_USBD_VID=0x128d
CONFIG_USBD_PRODUCT="xxx Test kit"
CONFIG_USBD_MANUFACTURER="xxx CO.,LTD"
CONFIG_USBD_MSC_CLASS=y
CONFIG_USBD_MSC_LUNS_PER_INSTANCE=3
CONFIG_DISK_ACCESS=y
CONFIG_DISK_DRIVERS=y
CONFIG_FILE_SYSTEM=y
CONFIG_FAT_FILESYSTEM_ELM=y
CONFIG_UDC_STM32=y
CONFIG_USB_DC_STM32=n

Steps:

1. Install USB3CV on Windows 11
2. Choose USB device on USB3CV
3. Run Compliance Test
4. Test failed in 100%.

Is "USB MSC test" a in-tree Zephyr test?

[testo-jeff]

@JarmouniA Not in-tree Zephyr test, we use standard external test tool to do the test.
Here is the test tool:

Hi @marwaiehm-st ,

I can see good results from your test.
Can we expect to have one fully compliance with Windows and Linux working for v4.2 release?
What is the current status of USB-NEXT ? Which one we should use to release a product at moment ?

BTW, we are using STM32U58x/STM32U5Ax
