Description From 2005-04-29 09:22:42
При загрузке системы загружаются модули uhci-hcd и ehci-hcd. При втыкании 
флешки появляются ошибки типа

Apr 28 22:40:24 localhost kernel: usb 1-3: new high speed USB device using 
ehci_hcd and address 2
Apr 28 22:40:25 localhost kernel: usb 3-1: new full speed USB device using 
uhci_hcd and address 2
Apr 28 22:40:25 localhost kernel: usb 3-1: device descriptor read/64, error -71
Apr 28 22:40:25 localhost kernel: usb 3-1: device descriptor read/64, error -71

Если один из модулей выгрузить, то флешка обнаруживается нормально

Ошибка в модулях USB контроллеров.

Я спасаюсь вот этим:
options usbcore old_scheme_first=y
в /etc/modules.conf

В kernel-image-std26-{up,smp}-2.6.11-alt7 по умолчанию установлены параметры:
  old_scheme_first=1
  use_both_schemes=1
