Hi,
For some time now (at least since 3.0) I have been having issues with an
USB3 to Sata enclosure and xHCI. The device (174c:55aa ASMedia
Technology Inc) works perfectly fine on USB2 ports in Linux, as well as
on the NEC/Renesas uPD720200(A) USB3 controller in Windows, but not so
on any Linux kernels that I've tried (all mainline).
Today I've built 3.8.6, enabled debugging and usbmon, and I've captured
lspci, lsusb, dmesg and usbmon (both text and wireshark) data here:
http://dx.infernix.net/renesas/
Device insertion happens around the 21:50:15 mark, and isn't removed
during the logs. Some excerpts in no specific order:
Apr 9 21:50:16 believe kernel: sd 7:0:0:0: [sdc] 976773168 512-byte
logical blocks: (500 GB/465 GiB)

Apr 9 21:52:54 believe kernel: hub 4-0:1.0: logical disconnect on port 2
..
Apr 9 21:52:54 believe kernel: usb-storage: usb_stor_post_reset
It constantly cycles into resets. From time to time in previous kernels
I was able to mount it and copy some data, but after seconds of copying
data it would reset and it would lose the SCSI device. With 3.8.6 I
can't even do an fdisk -l /dev/sdc because it will just reset before
that even happens. Plug it into an USB2 port and all is well with the
world. Boot to Windows on USB3 and I can copy data with 100MByte/s to
and from it.
Is this device not working properly in Linux due to lack of vendor
documentation for the USB3 controller, or is something else going on
here? Could someone please shed some light on this?
Thanks!
