In the meantime I tested with 3.2.64, 3.4.104, 3.10.60 and 3.12.32 and
had no problem, i.e. GNU `ddrescue ` 1.17 processes the device without
kernel panic (1.5 TB with > 7000 errors recognized and copied on a
damaged device).
In 3.14.24 I don't get a kernel panic, but `ddrescue` get stuck at
reading a damaged block while `dmesg` shows

3.17.2 still causes kernel panic with complete system crash with the
same device.
A current workaround therefore is to switch to 3.12.32 where you'll
definitely won't have problems with xhci (the USB driver) and probalby a
lot with btrfs (tradeoff).

Title:
USB 3.0 connection is unreliable + xHCI xhci_drop_endpoint called with
disabled ep
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
based on
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358871/comments/7 I
tested with the HDD enclosure IcyBox IB-351 series with USB 3.0 connection with
the same result (connection drops after 300 MB reading, error message "xHCI
xhci_drop_endpoint called with disabled ep" occurs sometimes, other devices
(e.g. Samsung HD103SI 1 TB HDD connected with 3.0 USB adapter to eSATA of
enclosure) read hundreds of GB before failing, but definitely do before reading
1TB). Reading tested with `dd`, `gpart` and `btrfsck`.
Also confirmed on Lenovo IdeaPad-Z500 after BIOS update to 71CN51WW(V1.21)
(changelog didn't indicate any USB issues anyway). Also confirmed with 3.16.3
and 3.16.0-14 on Ubuntu 14.10-beta1 after updates.
The issue seems to cause failure of ASIX AX179 gigabit ethernet chip as well,
but is independent from the usage of the ethernet adapter.
I'm without any clue and stuck with an unreliable USB and ethernet connection
which basically means no I/O out of the machine!!
