Hi,
I bought an Seagate BackupPlus Hub 4TB external hdd, but I can't mount.
lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-mtk/1p, 5000M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/3p, 5000M
|__ Port 1: Dev 3, If 0, Class=Mass Storage, Driver=uas, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-mtk/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/3p, 480M
Please at least list basic information, Xiaomi Router 3G?
Does it work using 18.06.2 and/or snapshots?
Have you tried the Seagate HDD on another device to verify that its working?
A micro USB cable Type B (like what you have for some Android phones) can be plugged in a USB 3.0 disk, in which case it will function as USB 2.0.
Alternatively you can use a USB 2.0 extension cable (male to female) as intermediate between your HDD cable and the router.
Just make sure it's USB 2.0. If in doubt, look inside the connector to see how many pins there are. See the image below is for a USB 3.0 cable. USB 2.0 cables have only the 4 first pins
EDIT: I reinstalled the UAS driver and it worked with the 2.0 cable.
Is there nothing to do about write/read speed?

These are the limits of USB 2.0 bus. Theoretical speed of 60 MB/s, but you would get around half that amount due to protocol overhead. At least now you have the HDD working while you are looking into the solution for USB 3.0.
Just trying on OpenWrt 19.07.2 r10947-65030d81f3, MediaTek MT7621 ver:1 eco:3 and the problem is still there.
With an USB 2.0 cable/adapter the device is forced to 2.0 and the external HD works, BUT with the bandwidth is limited.
Any solution?
