Hi!

I upgraded my DIR-505 to 21.02.1 using openwrt-21.02.1-ath79-generic-dlink_dir-505-squashfs-sysupgrade.bin and found that the USB port wasn't working.

I then reset the device(long pressed the reset button) and the USB port still doesn't work.

Upon investigation I found that the kmod-phy-ath79-usb package doesn't contain any kernel modules.(Only 2 text files.)

Supply the following if possible:

  • Device problem occurs on

D-Link DIR-505

  • Software versions of OpenWrt/LEDE release, packages, etc.

BUILD_ID="r16325-88151b8303"
OPENWRT_BOARD="ath79/generic"
OPENWRT_ARCH="mips_24kc"
OPENWRT_TAINTS=""
OPENWRT_DEVICE_MANUFACTURER="OpenWrt"
OPENWRT_DEVICE_MANUFACTURER_URL="https://openwrt.org/"
OPENWRT_DEVICE_PRODUCT="Generic"
OPENWRT_DEVICE_REVISION="v0"
OPENWRT_RELEASE="OpenWrt 21.02.1 r16325-88151b8303"

root@OpenWrt:~# opkg info kmod-phy-ath79-usb
Package: kmod-phy-ath79-usb
Version: 5.4.154-1
Depends: kernel (= 5.4.154-1-79c5dc6db69102eb2943a96b9bec8b63), kmod-usb-core
Status: install ok installed

Installed-Time: 1635066095

  • Steps to reproduce

    root@OpenWrt:# opkg files kmod-phy-ath79-usb
    Package kmod-phy-ath79-usb (5.4.154-1) is installed on root and has the following files:

The Reported Version should be openwrt-21.02 and not Trunk.

Doesn't look like I can edit it.

Same issue here. opkg package kmod-phy-ath79-usb package doesn't seem to contain any kernel modules. I'm on MikroTik RouterBOARD wAPR-2nD (wAP R), using openwrt-21.02.1-ath79-mikrotik-mikrotik_routerboard-wapr-2nd-squashfs-sysupgrade.bin.

The easy part:

If a kmod package doesn't contain the .ko module, it's very likely that the module code was instead compiled into the kernel itself.

In the case for kmod-phy-ath79-usb in ath79/generic, ath79/mikrotik (in both openwrt-21.02 and master/snapshot):
https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/generic/config-default#L19-L20
https://github.com/openwrt/openwrt/blob/openwrt-21.02/target/linux/ath79/generic/config-default#L19-L20
https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/mikrotik/config-default#L32-L33
https://github.com/openwrt/openwrt/blob/openwrt-21.02/target/linux/ath79/mikrotik/config-default#L30-L31

they all set:

CONFIG_PHY_AR7100_USB=y
CONFIG_PHY_AR7200_USB=y

(it's also set in the tiny and nand sub-targets (although nand only has CONFIG_PHY_AR7200_USB=y... this is because nand is only a thing on the later SoCs)

So, I think the USB-PHY driver is included and the missing .ko is likely not the problem.

I upgraded my DIR-505 to 21.02.1 using openwrt-21.02.1-ath79-generic-dlink_dir-505-squashfs-sysupgrade.bin and found that the USB port wasn't working.

I then reset the device(long pressed the reset button) and the USB port still doesn't work.

This device has a AR9330/1 SoC. These are special, because it uses a chipidea2 usb host controller instead of "generic-ehci" of AR934x+ (and later SoCs). For this it has/needs a special kmod-usb-chipidea2. But it should be included as well. Does the USB come back after a power-off / power-on cycle (by removing the power plug).

if not, I have more questions:

  • what sort of device are you connecting? Is it a usb-stick, printer, modem, usb<->sata bridge, webcam, etc...?
    (And do you have the kmods for those devices installed as well?)
  • Is the usb host controller enumerated in the system's boot log?
  • Are there any sensible entries (host + device connected on the usb port) in /sys/kernel/debug/usb/devices?
  • (can you measure if there's power on the USB 5V+ rail?
    be careful, if you plan to use a multimeter for this: Take care to not short out the port in the process!)
  • (was there a previous release on which the port worked?)
