Did you disable threads in seabios (either via the kconfig option or
via the /etc/threads runtime option)?  It's not recommended to disable
threads, and the USB code is less capable of handling timeouts when
threads are disabled.  Can you retry (and send the log) with threads

If that fails, can you also try disabling CONFIG_USB_EHCI in Kconfig
and send that log as well.
