In fact the log shows that the 30-second delay occurs in the middle of ohci1394 (Firewire) initialization, not USB initialization: Jun 8 05:26:35 upstairs kernel: ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[22] MMIO=[fbfff000-fbfff7ff] Max Packet=[2048] IR/IT contexts=[4/8] Jun 8 05:26:35 upstairs kernel: ohci_hcd 0000:02:0a.0: urb f71cb680 path 2 ep1in 5e160000 cc 5 --> status -62 Jun 8 05:26:35 upstairs kernel: hub 1-2:1.0: transfer --> -62 Jun 8 05:27:08 upstairs kernel: driver: '0000:02:0b.0': driver_bound: bound to device 'ohci1394' Jun 8 05:27:08 upstairs kernel: bus: 'pci': really_probe: bound device 0000:02:0b.0 to driver ohci1394 Those -62 errors from ohci_hcd are red herrings. To test this, try booting with "nousb".
