Also confirmed here, dmesg & lspci attached. Workaround 1: "rmmod ehci_hcd" does *not* work, at least with the USB flash key I'm testing with here.
Workaround 2: adding 'irqpoll' kernel parameter *does* work (although there are some odd-looking log messages with this USB key plugged in, see attached dmesg output). -- usb change between 2.6.15-23 and 2.6.15-26 breaks working setup https://launchpad.net/bugs/54419 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
