The changes in question only affect configurations with CONFIG_USB_SERIAL_EDGEPORT_TI and/or CONFIG_USB_SERIAL_OMNINET enabled. Both are not enabled in any of the affected builds (it was only applied since it fixes a CVE). It is therefore very unlikely that the problem is caused by CL:515207 and/or CL:515204. I'll do some more research, and may possibly revert the patches in question for simplicity in the affected releases, but that will very likely not fix the problem.

Given #3, reassigning to yueherngl@chromium.org to check if this could have been caused by the libusb update (https://chromium-review.googlesource.com/513502).

yueherngl@ can you look at CL in c#4 to confirm if this is the culprit here?

I will try to see if I can reproduce the problem, then revert the change to see how that goes to confirm. Thanks.

[Auto-generated comment by a script] We noticed that this issue is targeted for M-60; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-60 label, otherwise remove Merge-TBD label. Thanks.

RE: #12 Thanks for updating. Not sure if this problem has anything to do with libusb then? Is it possible to bisect and narrow down the range? Thanks again.

Things changed on M60 too - at 9592.12.0 - https://screenshot.googleplex.com/3r7qwKHoM21 And the diff with .11 build shows no much at https://crosland.corp.google.com/log/9592.11.0..9592.12.0 Could it be fixed by https://chromium-review.googlesource.com/c/525055/ on M60? It's a merge of the original change https://chromium-review.googlesource.com/c/523017, that went in with R61-9623.0.0 - the build we see M61 fixed.
