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:

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.

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.

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.

[HiFiPhile]

I don't have the Blue Pill but an ancient minimal board (Rev.Y chip).
Trying to make CDC and MSC requests concurrently but unable to reproduce it.

Your log looks like having some communication issue, could you verify your cabling, or a bad unit with soldering issue ?

[luftaquila]

There was no issue with eye inspection on the board and the cable used worked fine in communication with other boards.

[HiFiPhile]

Could you please test with cdc_dual_ports example and make traffic between 2 ports using something like hterm ? To see if there is a signaling issue.

[luftaquila]

When I tried cdc_dual_ports on STM32F103 Blue Pill, the Windows Device Manager recognizes both ports as TinyUSB CDC ports, but only one of them was able to open. It seems like that the example should echo the input, but nothing had shown on the serial monitor.

By the way, I tried cdc_msc example on STM32F401 Black Pill and both MSC and CDC classes worked well. But when I tried cdc_dual_ports on STM32F401, Windows devmgmt shows error on USB Composite Device and none of the ports are appearing.

Now I have no idea about which one is the problem, but I think I'll move to stm32f401 to use msc&cdc composite project.

[HiFiPhile]

Hum the problem becoming interesting...
Both MCU are widely used and no similar issue reported so far.

Is there anything special about your host pc ?

Did you have any stability issue downloading the firmware with DFU ?

[luftaquila]

I don't think so, because I program my MCU several times a day and always happens same. I'll try more and tell you if I figure out something more. Thank you very much for your help.
