MSC inquery request causes USBD Bus Reset #2753

Open luftaquila opened 1 month ago

Operating System

Windows 11

Board

STM32F103C8T6 Blue Pill

Firmware

examples/device/cdc_msc

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:

EventData 

  DeviceInstanceId USB\VID_1999&PID_0513&MI_02\7&77ff710&0&0002 
  DriverName usbstor.inf 
  ClassGuid {36fc9e60-c465-11cf-8056-444553540000} 
  ServiceName USBSTOR 
  LowerFilters  
  UpperFilters  
  Problem 0x0 
  Status 0xc00000e5

How to reproduce ?

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

try to see if https://github.com/hathach/tinyusb/pull/2750 fix your issue

luftaquila commented 1 month ago

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.
