Hi
>Is there any way for you to tell which protocol Windows uses
(usb-storage or UAS)?
I checked that the device manager was not load the uas driver, And this
lower write speed for win10 doesn't seem to use uas protocol for this
device.
if you have questions for [PATCH v7 3/3], I can continue to
investigate thinkplus(0x17ef, 0x3899) and first submit patch v7 1/3 and
patch v7 2/3.
you have anything unclear ,can ask me or advise me？
Thanks!

Hi:
ok,I have upated to v7.
Sorry , The information in the previous answers about thinkplus(0x17ef,
0x3899) comes from the tester, which is somewhat confused.
I just get the device from other department and the detailed test data
are as follows:
Test the thinkplus(0x17ef, 0x3899) speed by gnome-disk-utility tool.
linux(load uas)： linux(not load uas):
read： 394.2 MB/s read: 382.2 MB/s
write: 377.4 MB/s write: 347.8 MB/s
---------------------
win10(lower than linux,but more stable):
read : 388.1 MB/s
write: 320 MB/s
The main performance differences is write speed.but load uas can cause error
after long run, not good compatible with uas, So two bosses can
consideration for the third patch is it feasible.
Is there any way for you to tell which protocol Windows uses
(usb-storage or UAS)?
