Коллеги, прошу помощи,

На собственной плате на AT91SAM9G45 имеем проблему с USB EHCI под линуксом:
какое USB 2.0 HS устройство не подключаем, оно сначала регистрируется как ЕНСI, потом через N секунд отваливается, потом пытается снова зарегестрироваться и так далее. После таких нескольких попыток порт бывает зависает на совсем или сваливается на OHCI.

1. В чем искать причину?
2. Подтвердите, у кого high speed USB таки работает на AT91SAM9G45.

использую плату со Starterkit.ru на 9g45 - таких проблем не наблюдаю, USB брелки, USB/SD переходники, USB-PATA, USB-SATA все отлично работают в HS
был интересный прецендент, когда подключил на USB-PATA старенький винт 1.4Г, так при интенсивном обмене он терялся - вылечил более мощным блоком питания.
Я к тому, что попробуйте БП заменить. И глянуть осциллом - все ли с питанием хорошо..

все очень просто - это отобразился внешний хаб на 4 порта
конфиг следующий - на плате стоят два ЮСБ порта от 9G45, в один напрямую подключен винчестер через USB-SATA, во второй порт воткнут USB hub (4 порта) и флешечку я втыкал в него, в этот же хаб подключаю крысу и клаву
если что-то не так - озвучьте чего желаете увидеть - по возможности попробую изобразить (вечером)..

если в софтовой части, то брал ванильное ядро, подпиливал под существующую плату - USB ветку вообще не трогал..

упс.. под рукой ядро только на винчестере, с него все и гружу. но! за ванильность уже поручится не могу..
