MSC inquery request causes USBD Bus Reset

What happened ?
When put the USB to the host, USB Mass Storage device appears. But it refreshes few times, then marked error.
As shown in the log output below, there are always 6 times MSC Inquery requests. And it always immediately triggers the USBD Bus Reset. No other SCSI calls are received at all. Just 6 inquery, and bus resets.
While the device is marked error, Device Manager's Bus reported device description shows the correct desciption that I set in the tud_msc_inquiry_cb() call.
Windows reports the bus error:

How to reproduce ?
No OS, just call tusb_init() after all HAL init finishes. Then, call tud_task() in infinite loop.

I have checked existing issues, dicussion and documentation
- I confirm I have checked existing issues, dicussion and documentation.
Well, I checked out to the fix-ch32v203-setup and builded it, now it seems to be fail at the earlier stage of the initialization.
Now Device Manager shows Unknown USB Device (Device descriptor request failed), and TinyUSB log output is way shorter:

It seems like almost every transfer triggers the USBD Bus Reset.
If I keep retry, sometimes it goes a bit far and showed as USB Composite Device with error. I think this is just a problem of timing that hosts resets the device.

USBD Suspend : Remote Wakeup = 0
When I checked out back to the master branch and try it again, the result is same with the original issue.
Thank you for your support!
The most recent master that have merged fix-ch32v203-setup still presents the issue.
This is the log output by the current master:
