Noticed my "Kingston DataTraveler G2" is unusable on kernel 6.9.x, constantly resetting in a loop:

Proceeded to bisect the kernel, which points to commit 4f53138fffc2b18396859aa4ff3e7ef2b0839c2b <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4f53138fffc2b18396859aa4ff3e7ef2b0839c2b> causing the issue to surface.
Changing USB port made no difference. Tried the same device on a different computer using kernel 6.9.2 - issue replicates.
Attached bisection log, systemd journal kernel logs.
Thank you for the detailed report and also for having bisected this issue.
Does the patch below help (compile-tested only)?
Thanks,
Bart.
