Hello, I have got the following eSata 4-bay device:
http://www.mediasonic.ca/product.php?id=1357292050
Motherboard Asus M5A97 EVO R2.0 with eSata controler: 04:00.0 SATA
controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 01)
As you can see, the 4-bay device needs Port Multiplier, in Windows 7
everything works fine (just saying, hardware is OK), all 4 disk drives
are detected, but in linux not a single drive is detected! Here is dmesg
output after powering 4-bay device off and on again:

Any ideas, how can I get this device working in linux?
BTW got this mail in #kernel channel @ freenode! :)
Thanks, best regards - Fleck
