Hi,
I am using a salvaged (from an external Toshiba spinning disk) SATA
- USB 3 adaptor with a VLI701-04 chip behind a ASMedia Technology Inc.
ASM1042 SuperSpeed USB Host Controller (ExpressCard slot).
I have attached a Samsung sereis 840 SSD and whenever I dd some data
onto the disk, the drive disconnects and then reconnects as a
different /dev/sd*. Running 3.9 kernel (also happened with an older
one). I know that I should not reuse that controller for such high
bandwidth operation, but maybe there is a tweak (using USB 2 works,
but I was hoping to get more than 30 MB/s from this thing ;-) to make
it work?
Many thanks for pointers!
Stephan
