Wen using the usb 2.0 driver on my Nforce 4 system when transferring Multiple files it freezes during the file transfer requiring me to reboot the computer and to unplug the drive then replug it to regain access to the drive. It affects Mac file systems and Fat file systems.
Hi what's your motherboard make/model? Does it happen with an external USB hard drive? I.e. what kind of peripheral does it happen with? All of them or just a specific one?
From what you ve said, its hard for me to distinguish whether this is coming from the usb device or the driver. I know of one HARD DRIVE that does NOT work as a USB hard drive here it is: MDL MD00400-BJDW SATA 40GB will work fine as a SATA drive but NOT as a USB drive - producing a
102.342  IOUSBPipe[0x3896280]::Write - invalid write on a stalled pipe
If you have the 'debugging' version of the IOUSB Family installed, you can run the usb logger in XCode say level 3, and then start the file copy and read off the logger output. Otherwise, are there any entries in the system log? If none of this makes sense, pls. post
uname -psrv, kextstat, and ioreg | grep USB, and /var/log/system.log | grep USB (this one from last reboot only pls.)
- And, what happens when you are copying from one USB device to another? We would need to rule out ATA/SATA drives as causes as well.
Anyhow, just some ideas...
