usb3 problem

Hi there!

I installed a new transcend pdu3 usb3.0 expansion card and cannot access my usb drives
The expansion card is recognized by the kernel:

my kernel:
uname -a

Linux eisbaer 3.2.1-2-ARCH #1 SMP PREEMPT Mon Jan 23 12:40:01 UTC 2012 x86_64 AMD Athlon(tm) II X4 640 Processor AuthenticAMD GNU/Linux

relevant lscpi line:

relevant lsusb line:

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

There is NO dmesg output if I attach the device (Samsung M3 Station, 2 Terrabyte) to one of the two usb-3 ports. The drive works normally using usb-2.

Booting with the attached device doesn't work either.

Does anyone have an idea?

Thank you,
Dominik

Re: usb3 problem

Ok sorry for the inconvenience.
The problem was that I forgot to connect the power adapter to the transcend card.

Greetings
