USB sometimes stops working completely

[i509VCB]

Once in a while I get an issue where USB just suddenly stops working. Mainly when using probe-rs.

This is the second time I have encountered this. The first time I could not capture any additional info because the file system was unresponsive.

oops from dmesg output:

oops.txt

uname -a:

Linux verdigris 6.12.4-400.asahi.fc41.aarch64+16k #1 SMP PREEMPT_DYNAMIC Thu Dec 12 10:57:58 UTC 2024 aarch64 GNU/Linux

After this a USB flash drive will not be detected and probe-rs info never returns (likely because the USB stack went kaput).

This is an HID bug in the kernel around hid_bpf_dispatch, not just limited to USB. See here: #344. Would be really helpful if you can find a way to reliably reproduce this, I tried some HID class devices and couldn't make it happen.
