Where did you put it? I don't know much about USB, but by looking into the ehci-pci.c I added this to the ehci-au1xxx.c, after ioremap of hcd->regs: ehci = hcd_to_ehci(hcd); ehci->caps = hcd->regs; ehci->regs = hcd->regs + HC_LENGTH(readl(&ehci->caps->hc_capbase)); Is this O.K.? Now, with this I get: [4294668.620000] au1xxx-ehci au1xxx-ehci.0: Au1xxx EHCI [4294668.626000] au1xxx-ehci au1xxx-ehci.0: new USB bus registered, assigned bus number 1 [4294668.634000] au1xxx-ehci au1xxx-ehci.0: irq 29, io mem 0x14020200 [4294668.640000] au1xxx-ehci au1xxx-ehci.0: USB 0.0 started, EHCI 1.00, driver 10 Dec 2004 [4294668.649000] hub 1-0:1.0: USB hub found [4294668.653000] hub 1-0:1.0: 0 ports detected [4294668.762000] au1xxx-ohci au1xxx-ohci.0: Au1xxx OHCI [4294668.767000] au1xxx-ohci au1xxx-ohci.0: new USB bus registered, assigned bus number 2 [4294668.775000] au1xxx-ohci au1xxx-ohci.0: irq 29, io mem 0x14020100 [4294678.361000] BUG: soft lockup detected on CPU#0!
