Update the detail command to reproduce the issue:
./vts-tradefed run singleCommand vts --logcat-on-failure --skip-device-info --module "HalUsbGadgetV1_0HostTest" -t com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest#testMtp -a arm64-v8a

Hi, guys,
I have a further look for this issue, and found the time the kernel device appear in host & the time the kernel device appear in container is different.
For host: $ stat 3-8:1.0 File: 3-8:1.0 Size: 0 Blocks: 0 IO Block: 4096 directory Device: 15h/21d Inode: 1729821 Links: 6 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2021-01-11 13:26:25.000047220 +0800 Modify: 2021-01-11 13:26:25.000047220 +0800 Change: 2021-01-11 13:26:25.000047220 +0800 Birth: -

There are 23 seconds' gap there, but the MTP case: https://cs.android.com/android/platform/superproject/+/master:test/vts-testc... Just sleep 3 seconds after "svc usb setFunctions mtp true", that means there maybe time gap there that test_MTP case could find mtp device in /sys/devices.
Any suggestion for this? And still, could you share a job link how you run "VTS MTP test case" in docker test shell? Add @Milosz Wasilewskimailto:milosz.wasilewski@linaro.org maybe.

Hi, guys,
Recently we are running android VTS test in lava docker test shell, but find all MTP cases fail.
It reports:
01-08 07:42:38 D/ModuleDefinition: Running module armeabi-v7a HalUsbGadgetV1_0HostTest 01-08 07:42:43 I/ModuleListener: [1/5] com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest#testMtp FAILURE: java.lang.AssertionError: MTP not present at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.assertTrue(Assert.java:41) at com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest.testMtp(HalUsbGadgetV1_0HostTest.java:113)
I'm a little lost currently, so before I have a deep investigation, I want to know if you can share a link about this case: com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest#testMtp
I know you guys run android tests on other product always, could share a link for us to reference? Or with good luck you know what's the potential root cause for my failure?
Thanks.
