           Summary: USB DVDRW hangs during burning or reading (ehci_hcd)
    Kernel Version: 2.6.11
            Status: NEW
          Severity: normal
             Owner: greg at kroah.com
         Submitter: brihall at pcisys.net


Distribution: Gentoo 2004.3 (64-bit)
Hardware Environment: AMD64 3000+, MSI FISR VIA K8T800
Software Environment: cdrecord, 2.6.11 linus
Problem Description:
While burning a CD- or DVD-RW using an external USB enclosure
and a IDE burner, the burn process "hangs" and goes into these states:

root     11328  0.0  0.2   4400  1060 pts/1    S+   13:15   0:00
/bin/sh /net/scripts/burn /down/KNOPPIX_V3.8-2005-02-28-CeBIT_Edition.iso
root     11329  0.0  1.2   7244  6224 pts/1    DL+  13:15   0:00
cdrecord -v -overburn -data /down/KNOPPIX_V3.8-2005-02-28-CeBIT_Edition.iso
root     11331  0.0  1.2   7244  6224 pts/1    D+   13:15   0:00
cdrecord -v -overburn -data /down/KNOPPIX_V3.8-2005-02-28-CeBIT_Edition.iso

In the terminal window where I was burning, I get:

cdrecord: faio_wait_on_buffer for writer timed out.

In the kernel log, I get:
Mar 19 13:20:24 syrinx usb 1-3: USB disconnect, address 2
Mar 19 13:21:04 syrinx usb 1-3: usb_sg_cancel, unlink --> -19

Mar 19 13:21:04 syrinx usb 1-3: usb_sg_cancel, unlink --> -19

The device is working in USB 2.0 mode, according to
/proc/usb/bus/devices (not included here because once this problem
occurs I can no longer access it, although my low-speed USB mouse
continues to work). Burner is registered to the ehci_hcd driver.

The burner no longer responds to inquiries after the problem
occurs- cycling power on it doesn't help, I have to reboot.

Problem is intermittent, sometimes I can read or write an entire
DVD with no issues.


Steps to reproduce:

cdrecord -v -overburn -data /down/KNOPPIX_V3.8-2005-02-28-CeBIT_Edition.iso
