@achauras-qcom As far as I know, this host-based test isn't applicable for Lava. It might become relevant once we migrate to Axiom. Would you prefer to wait until the migration is complete? @mwasilew could you please confirm whether this test works on Lava? |
|
It might work in LAVA with container, but I don't know how useful this is. It tests the host rather than the device. In addition, there is no test script here, just a script that should be called with specific parameter. I'll try do demo this in LAVA if I have some time later today |

https://lava.infra.foundries.io/scheduler/job/75731#L1974 My changes are here: mwasilew@9847816 I only did minimal changes to show the concept. This test can be written without python (at least for linux). If you write the test in python, please use |
|
Thanks @mwasilew for the example. I'll try incorporating it. |
|
Regarding the use of the script for Host PC: Since USB is a master-slave protocol where master drives all communication, we need to test successful enumeration from master/host perspective only, which is the PC in this case. Our Axiom test scripts do the same. |
|
As far as I understand pyusb works on Linux, Windows and Mac. Do you have any logs/traces of the issue you're facing? The builds we currently use don't include any gadged/adb drivers, so this test isn't very useful. It may change later though. |
|
In Windows, usb.core.find(find_all=True) is returning an empty list, probably due to missing libusb drivers. If current builds don't include usb gadget drivers, then sure we can park this change for later. I will meanwhile work on resolving issues with my current script. |
Added test scripts to verify successful USB enumeration with user-input PID when DUT is connected to Host PC.
