Hi Werner,
Which debug level did you use to generate this much log info, i am using leve 7 but only a little when booting usb 2.0 driver using seabios 1.7.5 (git master).
Actually i have ehci driver issue on my Mohon Peak crb (rangeley SoC), no usb device (including mass storage and keyboard/mouse) is working with seabios 1.7.5, even it successfully booted into LINUX on my SATA HDD, the usb devices still didn't work.
but when i used seabios 1.7.0 (git stable), the log said this verion didn't support ehci 64bit, but after it booted into LINUX on my SATA HDD, the usb devices all worked well.
Once the machine boots into Linux, the SeaBIOS usb drivers have almost no effect. If the usb devices aren't working once Linux boots, you should look at your hardware and hardware config - it's not likely to be a SeaBIOS issue.
The messages within SeaBIOS are used to diagnose SeaBIOS' drivers that SeaBIOS uses to boot an operating system. If a USB device works under Linux, but for some reason SeaBIOS can't boot from it, then you would use the debugging information to diagnose it.
If you are having an issue with SeaBIOS, please set the debug level to 8, and then post the full log to the mailing list, as described at:

Also, please try to post in text only (not html) in the future.
