no trace of it in dmesg/lsusb;...
It is a newer model with 3.0 USB claimed 100% compatible
with 2.0 and in fact  mounts perfectly to my PC (old fedora 8 )

Any help will be appreciated

Mounts if connected to Sheeva via 4-port USB hub. Thats progress:-)
Why does't work if connected directly? Mystery...

Power supply from USB port?

Even USB extension cable will suffice... So it looks like it is not power supply problem

Similar issue here: just bought a 2TB CnMemory Spaceloop USB 3.0 HDD (Western Digital WD20EARS:http://www.storagereview.com/western_digital_caviar_green_2tb_review_wd20ears)

As "just" 5400 RPM hoped for a faster spin-up from power save mode as with my current Hitachi 7200 RPM drive. Cloning (rsync) the content both USB-drives connected via an USB-Hub to the SheevaPlug's USB-Port worked fine.

However why I tried to attach the 3.0 HDD directly to my SheevaPlug it's not recognized.

Same result with a friends SheevaPlug (he also bought that CnMemory). Though his GuruPlug "sees" it.

Seems I've to stick with an USB-Hub as "converter", now. :-(

For me extension cable works. No hub is needed
Not particular elegant solution...but alternatives are more costly

I tried to swap the USB-Hub with an ~ 1 m long USB extension cable, but without improving the situation. SheevaPlug still doesn't see the USB3.0 HDD.
Maybe I have to give it another try with an even longer one I have at home as well ...
