my OS is 10.5.7. I have an external hard disk, formatted as mac os extended (journaled), connect to my mac machine through USB cable.
I have used it for a while, but now it not working.
error showed in /var/log/system.log.
USBF: 2521.384 AppleUSBEHCI[0xa515800]::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 0, EP: 0)
kernel: USBF: 2588.616 [0xa6baa00] The IOUSBFamily was not able to enumerate a device.
but luckily, in my work place there is a mac with OS 10.4, so i had plugged the disk to 10.4, it worked!!!
I did checked "System Profile" on both machines (10.5, 10.4). under usb section , for 10.5 it shows USBEHCI, under 10.4, it shows USBOHCI.
I am not a expert on USB Device , can any one tell me why 10.5 cause the problem.
it was worked under 10.5
