Merhabalar
Geçenlerde Western Digital 250GB My Book Essential
harici harddisk ald?m. Ba?lad???mda harddiski görüyor
onda bir sorun yok fakat alet genelde çok yava?
çal???yor. Hangi porttan ba?larsam ba?layay?m EHCI
yerine OHCI controller'? devreye giriyor ve alet 480M
yerine 12M'de çal???yor. Ancak bir iki sefer
bilgisayar? yeniden ba?latt???mda 480M ile ba?land?.
Bunun için usb fareyi ve diskin usb ba?lant?s?n?
ç?kard?m, bilgisayar? öyle ba?latt?m ve ba?lad?ktan
sonra diski takt?m. Fakat bugün ayn?s?n? yapmama
ra?men yine 12M olarak görüyor. Neden olabilir? Her
seferinde yüksek h?zda çal??mas?n? nas?l
sa?layabilirim?
Usbtree ç?kt?s? ?öyle:
/: Bus 04.Port 1: Dev 1, Class=root_hub,
Driver=ohci_hcd/2p, 12M
/: Bus 03.Port 1: Dev 1, Class=root_hub,
Driver=ohci_hcd/2p, 12M
|__ Port 1: Dev 9, If 0, Class=stor.,
Driver=usb-storage, 12M
/: Bus 02.Port 1: Dev 1, Class=root_hub,
Driver=ohci_hcd/2p, 12M
|__ Port 1: Dev 3, If 0, Class=HID, Driver=usbhid,
1.5M
/: Bus 01.Port 1: Dev 1, Class=root_hub,
Driver=ehci_hcd/6p, 480M
dmesg ç?kt?s? ise ?öyle:
