Description:

ASM1042 is often paired with ASM1051E as a chipset in order to provide 2 USB 3.0 port and one SATA 6Gbps port on the same card. ASM1051E does not show up in lspci even though it is there, working. Works with gNewSense 3.0 LiveDVD and Trisquel 6.0 LiveCD out-of-the-box. I don't have any USB 3.0 devices to test with it, but USB 2.0 devices seem to work fine. SATA HDD drives can also be detected while SSDs cannot (August 2013).
