msc mode does not work again

[lida2003]

Current Behavior

It seems msc issue is back, see #5860

6.1.1FW + inav configurator 6.1.0 + AOCODARCH7DUAL （Onboard Flash） ==》 USB drive can't be opend, no BB log, but it can save log as TXT file.

Steps to Reproduce

1. Fly with blackbox enabled
2. blackbox tab, [save flash to file...] button works well, there is a txt log file
3. cli tab, [MSC] button works, but only usb drive "INAV_FC" appears, it can't be opened.

So we can't get BB log files.

Expected behavior

Open USB drive, and copy BB log files to the computer as it was.

Additional context

Only below U driver appears, it can't be opened.

• FC Board name and vendor: AOCODARCH7DUAL （Onboard Flash）
• INAV version string: 6.1.1 [AOCODARCH7DUAL]
• STM32 H743

Tested on INAV7 and H7

and everthing seems to be working. Slow and you have to wait circa 1m for files to appear, but works
