Hans Petter pointed to me to the _real_ solution of my problem, and I want to set the record straight: The USB2 stack works fine, the patch to vfs_mount.c makes the booting process more robust. The easiest way to make a system booting from USB mass storage is to exclude every usb- related device from the kernel and kldload the needed modules in boot/loader.conf: # /boot/loader.conf usb2_controller_ehci_load="YES" usb2_controller_ohci_load="YES" usb2_controller_uhci_load="YES" usb2_storage_mass_load="YES" My problem was a left-over "device ucom" in the kernel configuration, or actually, since I have "include GENERIC" at the top, the missing "nodevice ucom" line. It pulled in dependencies on the old USB stack. -c _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
