Unstable USB devices detection on Lenovo Yoga C630 WOS

[RussianNeuroMancer]

Hello!

I find that at least in case of branchy USB hub topology USB devices detection is unstable.

Topology: Lenovo Yoga C630 WOS is connected to Belkin USB-C 3.1 Express Dock HD F4U093 via front host USB-C port StarTech.com USB-C Hub HB30C5A2CSC and Dell UP3017 USB Hub is connected Belkin USB-C dock Type-A ports on the back.

Below is example of Kingston Digital 128GB Data Traveler Micro Duo USB 3C Flash Drive (DTDUO3C/128GB) connect attempt via Type-C port on StarTech.com USB-C Hub:

Same issue is reproducible with Transcend JetFlash 850 Silver 64GB (TS64GJF850S). Both flash drives works fine via same ports of same hub on same laptop, on Windows.

Below is example of Sony 64GB USB Flash Drive (USM64CA1/S) connect attempt via Type-C port on StarTech.com USB-C Hub:

After that laptop reboot, this doesn't happen in Windows, as you can guess.

Unfortunately, Sony flash drive is not my, so I would not be able to reproduce "reboot after device not accepting address" in the future (that why I didn't register this reboot issue separately) but I write down logs of this behavior just in case it could be useful.

On other hand Kingston and Transcend flash drives is my, so I will be able to reproduce "device descriptor read error" or test fixes for this issue in the future.

Little clarification regarding reboot log (Sony flash drive)

[18557.054323] FAT-fs (sdc1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
[18595.707381] xhci-hcd xhci-hcd.0.auto: ERROR mismatched command completion event

Second and following lines appear after my attempt to open flash drive in file manager.

Have you tried with a simple USB-C => USB-A adaptor?

[lag-linaro]

USB support is fully upstream. Please report it there instead.

May I also suggest that @jhugo might know who is now responsible for QCom USB development.

@lag-linaro

Currently I replacing Belkin USB-C 3.1 Express Dock HD F4U093 with StarTech TB3CDK2DP, and will try to reproduce issue once again when package arrive. Until then I will try to reproduce it with Dell DA300 in the next few days. When issue will be reliably reproducible on at least one of these two USB-C hubs - I will fill upstream bugreport.

Arrived StarTech TB3CDK2DP doesn't communicate with C630 at all, regardless of operating system (no charging, no single line in dmesg, nothing) and StarTech wasn't able to find cause yet (however they ordered C630 and already investigate this issue with laptop on hands).

With Dell DA300 this USB issue looks a little bit different. For example file manager could report that data successfully copied to flash drive, I unmount it, put flash drive into other device only to find out nothing was written. Next time it tried to run "sync" before unmounting, but this does not help. Unfortunately, I have to return Dell DA300 to owner tomorrow, so there is no much point in reporting this variation of USB issues as I would not be able to test possible fix.

I going for vacation for a few months, so most likely I will have a chance to investigate USB issues further (this time most likely with Dell WD15) only next year.
