B1300 won't tether a Samsung S8

Technical Support for Routers

In following the OpenWRT steps I’m seeing all the pieces loaded.

root@GL-B1300:~# lsmod|grep hcd
ehci_hcd               57344  1 ehci_platform
ohci_hcd               40960  1 ohci_platform
uhci_hcd               40960  0
xhci_hcd              126976  2 xhci_plat_hcd
xhci_plat_hcd          16384  0

I do see “kmod-usb-ohci” and “kmod-usb-uhci” both here. The OpenWRT guide shows the ohci as an alternative, probably shouldn’t be installed together.

Besides that, it looks like you got all drivers yup

  • Some devices (e.g. Asus WL-500g router, brcm47xx) additionally need the kmod-usb2 module (even though they only have an USB 1.1 controller)

  • Some devices (e.g. NLSU2, LinkSys WRT54G3GV2) additionally need the following packages:

opkg install kmod-usb-ohci-pci
opkg install kmod-usb2-pci

Saw this in the notes, these 2 are not installed on your device. If this isn’t it I’m out of ideas :sweat_smile: :man_shrugging:

The difference between B1300 and AR750s is USB3.0 vs USB2.0.

Can you give me these log when you plug S8 to B1300

logread
ifconfig -a

My previous post here w/logread for the S8 B1300 won't tether a Samsung S8 - #5 by wkearney99

Good to know the USB3 vs USB2 difference. Both the S8 and the S22 use a USB-C connector, but I don’t know which version they each support.

So just seems the USB does not work correct.
S8 is old. I cannot find a S8 now. Two years ago my workmate has a S8.

Did you miss the part where this cable and this phone is able to tether without a problem on an AR-750S?

Yes, as a phone the S8 is an older model, thus using it as a tethering modem.

28

No I didn’t miss. I just cannot find a S8 and test.

AR750S is USB2.0 and MT1300 is USB3.0 which I think it affected something

29

It’s not just the Samsung S8, I’m using a Quectel RM502 on a USB adapter and the B1300 will not recognize it either. The GLinet firmware has a glitch in the USB config file. It needs to be fixed ASAP!
