Bug 61101 – Timeout accessing USB hard drive

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Joel Campbell 2004-08-20 20:24:48 UTC]

I have a USB 2.0 hard drive that I connect to my laptop. After a few minutes of accessing the device I loose the ability to do anything with the drive. Syslog reports 'control timeout on ep0in'. I must unplug the device and plug it in again to regain access. The process then repeats after more access. I tried the same external hard drive on an iBook running 2.6.7-gentoo and had no problems even after moving data and doing a full drive find command. The iBook had USB 1.

Reproducible: Always
Steps to Reproduce:
1. Plug in external hard drive and mount it.
2. Access the drive in any way read or write.
3. Watch drive stop responding and errors begin to show in logs.

Actual Results:  
I lost access to the drive.

Expected Results:  
I should have access to the drive.

Running kernel 2.6.8-gentoo-r1 (also happened on all 2.6.7 releases)
emachines M6809 laptop
Hitachi 80GB drive in USB 2.0 enclosure. 
Connected to USB 2.0 port.
Last few entries in log before loosing access:

Has this ever worked on earlier kernels? What happens if you disable EHCI?

[Comment 2 Joel Campbell 2004-08-26 08:06:49 UTC]

I have tried with 2.6.7 and 2.6.8. Disabling EHCI makes it work somewhat better in the sense that it took longer before the timeout message. I do have non-storage devices that work fine so I think the problem is related to usb-storage.

Output from kernel bug

This is what happened after I reinserted a CompactFlash card in my card reader
after the reader had stopped responding with the now familiar 'timeout on
ep0in' message.

Looks like an upstream problem... Could you please compile a plain development-sources-2.6.8.1 and then send a detailed bug report to [e-mail] ? It is also helpful to enable USB debug and USB storage verbose debug messages.
