金胜的（kingshare）msata转usb3.0硬盘盒在linux的驱动问题需要禁用uas才行
windows 10工作很正常，但linux下面有问题， 估计是linux对这这种芯片的支持有问题？(这个好像跟实际的msata的SSD硬盘有关，现在发现有一款“金胜维KINGSPEC”在linux下不支持这个UAS，其他牌子的SSD正常，淘宝官网好像也是说不支持金胜维KINGSPEC的SSD)。
内核日志看UAS工作不正常，看到网上很多人遇到类似的问题，只好把UAS特性给关闭了，当作普通的USB storage来用，
但测试发现金庸UAS后如果插入的是USB3.0的接口还是工作的不正常的，还好插入USB2.0里面可以工作了，虽然读写速度可能有些下降，
但还能正常使用算不错了。
dmesg
If UAS is not disabled, the scsi host adapter was reset again and again.

Windows 10’s load the “BayhubTech Intergate MMS/SD” driver for this device, but no linux driver is found on BayhubTech site. Someone mentions a work around is “disabla UAS”, from the dmesg it seems that the device doesn’t response to specific UAS scsi command.
USB Attached SCSI (UAS)
UAS was introduced as part of the USB 3.0 standard, but can also be used with devices complying to the slower USB 2.0 standard. UAS drivers generally provide faster transfers when compared to the older USB Mass Storage Bulk-Only Transport (BOT) protocol drivers When used with an SSD, UAS is considerably faster than BOT for random reads and writes, but still well below the speed of a native SATA 3 interface (6 Gbit/s).
diable uas
the quirks parameter of usb-storage has the following foramt:
"VID:PID:flags",
the vendor_id and product_id can be found in dmesg or lsusb output.
see usb_stor_adjust_quirks function in
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/drivers/usb/storage/usb.c
"options usb-storage quirks=Vendor_ID:Product_ID:u" in modprobe conf file,
or try to set it at runtime.
