Hello, i am also affected by this bug...
my mainboard is an asus m3a78-t: amd 790gx chipset, amd sb750 southbridge. i don't know if it may help anyone, but atleast for me, i can reproduce the usb "reset" bug very easily with running an md5sum against my usb2.0 storage devices... (sudo md5sum /dev/sdX) wich, in my case, will trigger usb resets quite fast. i can reproduce this behavior with two of my usb 2.0 hdds, one western digital mybook (2.5" 250gb) and one seagate freeagent (3.5" 500gb). fyi, i tried the following "fixes", but usb2.0 is still exhibiting the "reset" bug: - kernel 2.6.27-11 from intrepid-proposed - ensuring that ehci_hcd is loaded before ohci_hcd/uhci_hdc - disabling usb autosuspend as recommended in comment #209 so when i run md5sum against my wd mybook or seagate freeagent, it's at some point starting to reset: [ 3373.785540] usb 3-5: reset high speed USB device using ehci_hcd and address 4 [ 3388.896040] usb 3-5: device descriptor read/64, error -110 [ 3404.112046] usb 3-5: device descriptor read/64, error -110 [ 3404.328024] usb 3-5: reset high speed USB device using ehci_hcd and address 4 [ 3419.440041] usb 3-5: device descriptor read/64, error -110 [ 3434.656037] usb 3-5: device descriptor read/64, error -110 [ 3434.873731] usb 3-5: reset high speed USB device using ehci_hcd and address 4 [ 3445.280030] usb 3-5: device not accepting address 4, error -110 [ 3445.392051] usb 3-5: reset high speed USB device using ehci_hcd and address 4 [ 3455.801525] usb 3-5: device not accepting address 4, error -110 ... ** Attachment added: "lsusb.txt" http://launchpadlibrarian.net/21692647/lsusb.txt -- ehci_hcd module causes I/O errors in USB 2.0 devices https://bugs.launchpad.net/bugs/88746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
