Re: full dmesg - Re: Firewire errors with Freecom Hard Drive Quattro and linux kernel 3.13 rc8: firewire_sbp2 fw1.0: status write for unknown ORB

[<pho...@ya...>]

Hello Stefan,

thanks for getting back to me. I am currently away from work and the new
4gb Freecom disk, but will be back with the disk on Wednesday. I can and
will do all the things you suggested. I can compile c without problems.

I this laptop with the firewire port I am using two older Freecom
Quattro disks (ones with USB 2.0 connector in contrast to the new one
with USB 3.0), they do work fine without problems, it does not matter
whether I connect them directly or if I daisy chain them.

I have also used a Western Digital MyBook Studio disk (silver enclosure)
with this particular laptop earlier without any problems.

Could you recommend some very good firewire cables, a certain
manufacturer maybe so that I could eliminate that potential problem? I
currently got the cables supplied with the freecom and western digital
drives, plus some from reichelt.de and some new delock ones bought from
amazon. They all work fine with the older freecom drives, but not with
the new 4tb freecom drive.

I saw that I have a firewire port on another computer with an asus
motherboard. I will try the freecom disk there next week too.

On this google code webpage https://code.google.com/p/jujuutils/ is this
requirement "package requires the new "Juju" FireWire stack.". Does the
new kernel use that juju firewire stack ?

Thanks
Best regards
