I tested your patch with 6.5.1. It seems to solve the issue and the kernel worked the same as 6.4.7.

I attached three log (dmesg) files:

• withpatch.log --- 6.5.1 + patch The kernel could detect both USB devices. No "-ETIMEDOUT: failed to

initialize core" message.

• nopatch.log --- 6.5.1 without any patches (case 1) The kernel could detect NETGEAR A6210 but not BUFFALO USB Flash Disk. That was happening less often (about 1 time per 5 boots).
• nopatch-succ.log --- 6.5.1 without any patches (case 2) The kernel could detect both USB devices even if it showed

"-ETIMEDOUT: failed to initialize core".

Please let me know if you need anything else.

Thank you. Kenta

Thanks for the report and the test!

I'll prepare a proper patch when v6.6 rc-1 is released. I need to cleanup and reduce some of the delays in this experiment.

BR, Thinh
