Description Thorsten Tasch 2005-01-08 04:45:23 UTC 
Distribution: Ubuntu Warty
Hardware Environment: Acer Travelmate 4000LMi

Problem Description: I can't use usb 2.0 high speed mode
(full speed works without problems).

output of "dmesg|grep ehci":
ehci_hcd 0000:00:1d.7: Intel Corp. 82801DB (ICH4) USB2 EHCI Controller 
ehci_hcd 0000:00:1d.7: irq 10, pci mem df931000 
ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 4 
ehci_hcd 0000:00:1d.7: USB 2.0 enabled, EHCI 1.00, driver 2004-May-10 
ehci_hcd 0000:00:1d.7: fatal error 
ehci_hcd 0000:00:1d.7: HC died; cleaning up

I often get the message "usb usb4: string descriptor 0 read error: -19".

I've tried to disable apic and acpi but I'm not successful.
