What's the problem

Certain USB-SATA-bridge chipsets do not properly pass SAT commands on to the SATA device when running in UAS mode, and to work around this problem Linux automatically enables the NO_ATA_1X flag for those chipsets. This turns off SAT passthrough... which in turn means that hd-idle is prevented from communicating with the device.

lsusb -t shows the driver used.

  • Here UAS is enabled.

How to temporary solve it

There are two approaches to get it to work with one of these devices, both involving setting a "quirks" flag for the device in question. A quirk set in this manner will automatically get cleared the next time the system is rebooted. Follow this guide if you want a permanent solution.

First of all you have to find out idVendor and idProduct for the device.

$ lsusb
Bus 002 Device 004: ID 2109:0711 VIA Labs, Inc. 
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Then unmount/unplug the device and run lsusb again. The missing entry is your device. In the case above idVendor is 2109 and idProduct is 0711.

  • If you don't care about the performance improvements the come from using UAS mode, you can simply use the IGNORE_UAS flag to tell Linux to stick with the usb-storage mode instead, by using the u flag on the usb-storage.quirks setting. Add to /sys/module/usb_storage/parameters/quirks:
2109:0711:u
  • If you want to continue using UAS mode and you are sure your particular device does properly support SAT mode even though the kernel detects it as a device that does not, you can override that default configuration and suppress the NO_ATA_1X t flag by passing an empty flag list in the usb-storage.quirks setting. Add to /sys/module/usb_storage/parameters/quirks:
2109:0711:

Finally you can mount/plug the device again.
