USB drive problem with Asus RT-AX53U

Hi all!

I'm having troubles connecting a USB drive (1 TB Toshiba DTB310) to Asus RT-AX53U router running OpenWrt 22.03.3.

This USB drive is formatted with ext4. I used it previously with ASUS RT-N56U router running Padavan's firmware. When I connect it to RT-N56U - it's recognised absolutely fine, I can mount it and read it's contents via ssh shell.

But when I connect the drive to RT-AX53U, i hear the repetitive sounds of, what I would call, "reading attempts" and the light on the disk flashes in sync with those sounds. The router cannot recognise the disk(

Here's some of my system info:

root@OpenWrt:~# ubus call system board
{
	"kernel": "5.10.161",
	"hostname": "OpenWrt",
	"system": "MediaTek MT7621 ver:1 eco:3",
	"model": "ASUS RT-AX53U",
	"board_name": "asus,rt-ax53u",
	"rootfs_type": "squashfs",
	"release": {
		"distribution": "OpenWrt",
		"version": "22.03.3",
		"revision": "r20028-43d71ad93e",
		"target": "ramips/mt7621",
		"description": "OpenWrt 22.03.3 r20028-43d71ad93e"
	}
}

Here are the "usb" packages I have installed:

root@OpenWrt:~# opkg list-installed | grep usb
kmod-usb-core - 5.10.161-1
kmod-usb-ehci - 5.10.161-1
kmod-usb-storage - 5.10.161-1
kmod-usb-storage-uas - 5.10.161-1
kmod-usb-xhci-hcd - 5.10.161-1
kmod-usb-xhci-mtk - 5.10.161-1
kmod-usb2 - 5.10.161-1
libusb-1.0-0 - 1.0.24-5
usbutils - 014-1

I have kmod-fs-ext4 - 5.10.161-1 installed too.

Here's "usb" grep of the dmesg command:

From it I can see all those unsuccessful attempts of connection, followed by immediate disconnection.

Can anyone advise on how to resolve this issue?

Sound like a power issue, try a powered hub.

Makes sense, thanks fort the idea. I'll try to get one and test.

Where did you get one anyway? I can't find such thing. Also having the same problem with the same device. Shame on the engineers of this router, at least make it powerful that much to run a HDD. Such a lazy design, asus sucks lately.
