I've taken a new system into use today and can confirm that the bug is NOT unique to alcor USB chips.
The system log gets spammed with this on trying to read from USB 2.0 mass storage devices: Dec 18 22:13:56 winter9 kernel: [ 2169.570023] usb 1-3: reset high speed USB device using ehci_hcd and address 2 I am also having severe problems with drive disconnects for 2,5" bus- powered USB units on the same system. (However the drives in question work flawlessly on an older Lenovo Portable system). The Device Manager shows this to be the USB root hub: 82801JI (ICH10 Family) USB2 EHCI Controller #2 Intel Corporation (ASUSTeK Computer Inc.) PCI (Peripheral Component Interconnect) It is a USB controller on an ASUS motherboard; P5QL - EPU (Intel P-43 Chipset). Hope this helps - this bug is unnerving. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
