Problem with external USB 3.0 drive - xhci_hcd WARN: transfer error on endpoint
 
1 Attachment(s)
I use slackware 14 64bit with stock kernel. Sometimes I got problems with using my external usb 3.0 2TB drive (ext4, LUKS-encrypted). After copying few GB from my drive it gets disconnected. When this happens I can't connect anything else to the same port until next reboot, I get only this in my logs:
Code:

hub 3-0:1.0: unable to enumerate USB device on port 2
However, sometimes I can copy 100GB file without problems. Another thing is that I have never encountered this problem when using Slackware 14 live boot DVD. Under windows 7 I had no problems too. So I can exclude usb port or hdd failure.

In encolsed log I got disconnected after copying 3GB of 100GB file.

Does this happen with kernel versions 3.6 and above?

I haven't tested. I use 3.2.29 kernel

Then please test. Not everything will be backported to 3.2.
