Собрал ядро 3.20.18 для acme-aria 9g25, конфиг для USB:
CONFIG_HAVE_AT91_USB_CLK=y
CONFIG_USB_HID=m
CONFIG_USB_HIDDEV=y
CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_SUPPORT=y
CONFIG_USB_COMMON=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB=y
CONFIG_USB_ANNOUNCE_NEW_DEVICES=y
CONFIG_USB_DEFAULT_PERSIST=y
CONFIG_USB_EHCI_HCD=y

CONFIG_USB_OHCI_HCD=y
CONFIG_USB_OHCI_HCD_AT91=y
CONFIG_USB_OHCI_HCD_PLATFORM=y

При подключении к USB устройств (например блютуз ACORP) получаю такие сообщения:

Пробовал на ядре 4.1.18 там устройство видится нормально.
