This one also looks nice, and plugable is known to be a Linux friendly company, and they should be available in the US: http://www.amazon.co.uk/Plugable-Lay-Flat-Docking-Station-ASM1053E/dp/B00D399JU2 I've ordered this one now ... I just ordered that one as well, and it looks like it doesn't have UAS exposed, even though the descriptors mention it: snip I wonder if this needs a vendor specific command to disconnect and reconnect in UAS mode? Or perhaps a firmware blob? I'll have to connect it under Windows with a USB bus analyzer and see what the driver does. Mine arrived yesterday and it does have UAS support (as alternate setting 1 for interface 0) in its descriptors, without needing any special commands. On a hunch I tried to reproduce your experience with my plugable dock, and if I turn it on without a harddisk in there it does not advertise uasp either, so likely it only advertises uasp if the harddisk is tcq capable (or some such), and without a harddisk it cannot determine that ... I wrote a small libusb program to get the super speed endpoint companion descriptors, and it can do up to 4 bulk streams on the uas data endpoints, so it seems like a perfect device to test uasp and bulk streams with. BTW we really ought to extend lsusb to list the number of streams an endpoint can handle in the endpoint info it prints with -v. I can load the Linux uas driver, after which I hit: https://bugzilla.kernel.org/show_bug.cgi?id=51031 So I'm happy to hear you've one too, I hope it will do uasp once you insert a harddisk, because then hopefully you can fix that bug :) If inserting a harddisk fails, ASMedia controllers have upgradable firmware inside them, so the first thing to try and get uasp working on your model is to try the firmware upgrade: http://plugable.com/2013/04/22/usb3-sata-uasp1-sleep-and-large-volume-firmware-update Note I did not need to do this, but judging from the descriptors you do seem to have slightly different firmware, yours has a manufacturer string of ASM1053E, where as mine has a manufacturer string of Plugable. I've attached my full descriptors (from when a harddisk is inserted into the dock). If that does not work I guess you should contact plugable about this, as said before various people in the FOSS community have good experience with them, they are quite FOSS / Linux friendly.
