USB Mass Storage перестал моунтится

Уважаемые гуру,

с недавнего времени меня имеет проблема неподсоединения моей флешки. Раньше всё было нормально. Работало на всех системах. Теперь работает только на венде...
Есть подозрения, что перед тем как флешка перестала подсоединяться, она была вытащена без umount из порта.
Итак, сейчас происходит следующее:
1. как только вставляю в порт, dmesg выводит

usb 5-5: new high speed USB device using ehci_hcd and address 8

2. Вроде всё ничего, но потом:
