Hi,
I'm testing Coreboot with SeaBIOS as payload on my old Alix.2C2. When trying to boot from an USB device I get the following error:

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 enabled.
If that fails, can you also try disabling CONFIG_USB_EHCI in Kconfig and send that log as well.
I get the same error with threads enabled. Disabling ehci did not help either. Logs are attached as requested.
It looks like the USB device is successfully identified and configured, but when sending the "inquiry" command to the drive behind the USB interface the connection halts. Not sure why that would be - it could be something with the controller, but it's odd that it happens with both the ohci and ehci controllers.
If you boot to linux (using some other bootable device) what does 'lsusb' and 'lsusb -t' report? Have you tested with a different type of usb drive?
