USB Mounting Issues

fgr-17 · July 22, 2021, 11:36pm

Hey, it's my first post on this Forum.
I'm using a custom build of OpenWRT 17.01.4 r3560-79f57e422d on a project, over the AR9344 processor. This can't be changed so I can't update or upgrade the system.
I'm trying to mount an USB Mass Storage Device, I've installed the following packets:

kmod-usb-core - 4.4.92-1
kmod-usb-storage - 4.4.92-1
- kmod-scsi-core_4.4.92-1_mips_24kc *
kmod-usb2 - 4.4.92-1
libusb-1.0 - 1.0.21-1
usbutils - 007-7

And for the ext4 filesystem support:

libext4fs
e2fsprogs
kmod-fs-ext4
- kmod-lib-crc16
- kmod-crypto-hash
- kmod-crypto-crc32c

After that, I can see the devices properly on lsusb, but I can't see anything on /dev/sd* nor /mnt. In fact, I don't have any /dev/sd* file.

The dmesg output shows that the usb is recognized, but after a few seconds is reseted:

3044.549379] usb-storage 1-1:1.0: USB Mass Storage device detected
[ 3044.557507] scsi host5: usb-storage 1-1:1.0
[ 3067.185883] usb 1-1: reset high-speed USB device number 7 using ehci-platform

Do you have any suggestions on this? thanks in advance!

Looks like you are missing block-mount and kmod-usb-ohci and kmod-usb-uhci

Also can try to install lsblk and post output
opkg install lsblk
lsblk -f

Hey faser, thanks four your quick reply!

The block-mount packet was installed, but I didn't install kmod-usb-ohci and kmod-usb-uhci since the AR9344 processor has USB2.0 support. Anyway, I've already installed them now.

The dmesg shows the following during the boot process (only relevant lines):

(the usb was connected after powering the board)

I'm still seeing the same issue:

Wed Jul 21 16:18:31 2021 kern.info kernel: [  286.785890] usb 1-1: new high-speed USB device number 3 using ehci-platform

lsblk -f shows:

mtdblock5                     /overlay

Is it necessary to manually create the /dev/sd file? what packet is responsible for that?
my /dev folder contains the following files:

What is the USB Device you are trying to connect?

fgr-17 · July 23, 2021, 4:02pm

I'm trying to connect an USB mass storage device. It is a 32Gb Sandisk Pendrive

lsusb reads it correclty:

root@lwconnect:/tmp# lsusb -t
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-platform/1p, 480M
    |__ Port 1: Dev 26, If 0, Class=Mass Storage, Driver=usb-storage, 480M

root@lwconnect:/tmp#

anon50098793 · July 23, 2021, 4:17pm

not saying this is the case with yours... but the one I owned was unreliable... never had any (factory-quality) problems with other sandisk sticks...

your earlier dmesg is typical of missing fs kmods (or scsi)

opkg list-installed | grep -E '(^kmod-fs|^kmod-scsi|^kmod-usb)'

(edit: i see you posted them near the top looks ok except maybe 'nls/codepage' type package may be missing)

these are whats on my system... no idea of they are needed or not;

kmod-nls-base
kmod-nls-cp437
kmod-nls-iso8859-1
kmod-nls-utf8

was pretty sure the fs packages pulled in what they needed from above tho'... ok... looks like they were pulled in by fs-vfat... except for

/usr/lib/opkg/info/kmod-usb-core.control:Depends: kernel (=5.4.132-1-272d8d859b9c04efc790e7b6c91cc80f), kmod-nls-base

usb-core wanted nls-base

I think you should uninstall;

kmod-usb-uhci

based on the errors above... and maybe try

kmod-usb-ehci

fgr-17 · July 23, 2021, 4:49pm

This pendrive is working correctly on Debian, windows and macOS. I also tried a Kingston pendrive with the same results.

here's the output of opkg list:

root@lwconnect:/tmp# opkg list-installed | grep -E '(^kmod-fs|^kmod-scsi|^kmod-usb)'
kmod-fs-autofs4 - 4.4.92-1
kmod-fs-ext4 - 4.4.92-1
kmod-scsi-core - 4.4.92-1
kmod-scsi-generic - 4.4.92-1
kmod-usb-core - 4.4.92-1
kmod-usb-dwc2 - 4.4.92-1
kmod-usb-ohci - 4.4.92-1
kmod-usb-storage - 4.4.92-1
kmod-usb2 - 4.4.92-1
kmod-usb2-pci - 4.4.92-1
kmod-usbmon - 4.4.92-1

I'll try with these NLS packets. They're related to Native Language Support... I have this already installed:

kmod-nls-base - 4.4.92-1

The AR9344 processor has USB2.0 support, so the ehci module should work. I tried to install uhci module but shows some errors during the booting process. But the other USB1.0 driver, ohci does work

mike · July 23, 2021, 4:52pm

Sometimes kmod-usb-storage-uas is needed in addition to kmod-usb-storage.

fgr-17 · July 23, 2021, 4:55pm

I'm on OpenWRT 17.01.4. Is that packet available on this version? Because I've searched everywhere and still can't find it on downloads.openwrt.org nor compile it with make menuconfig. Maybe that packet exists from the 18 version onwards

The BOT driver is included in kmod-usb-storage?

mike · July 23, 2021, 5:25pm

I can't find it in 17.. either, just 18.. onward, sorry about that.

flygarn12 · July 23, 2021, 6:33pm

17 and 18 are both end of life and obsolete. Why not use 19.07.7 that is actually supported , very stable and still maintained?

fgr-17 · July 23, 2021, 7:30pm

I wish I could update to 19, but it's not my decision

fgr-17 · July 23, 2021, 7:47pm

should the uci show output show something related to the usb? like a trigger or something? because the original snapshot was built without USB support, and I'm trying to add it lately. But for example, on the sources I can see things like:

file config_generate:

usb)
			local device
			json_get_vars device
			uci -q batch <<-EOF
				set system.$cfg.trigger='usbdev'
				set system.$cfg.interval='50'
				set system.$cfg.dev='$device'
			EOF
		;;

and I don't have anything similar in the uci configuration. That lines are includes in case that CONFIG_USB_SUPPORT is set...I think:

file target.mk

ifneq ($(CONFIG_USB)$(CONFIG_USB_SUPPORT),)
      ifneq ($(CONFIG_USB_ARCH_HAS_HCD)$(CONFIG_USB_EHCI_HCD),)
        FEATURES += usb
      endif

flygarn12 · July 26, 2021, 9:44am

Who has a mindset to use old non original firmware and at the same time not be interested to upgrade it?
That makes no logical sense what so ever.

fgr-17 · July 26, 2021, 2:25pm

bussiness logic != programmer logic

flygarn12 · July 27, 2021, 6:40am

It ain’t a meaningful business logic ether…unless your biggest dream in business is to be exploited!?
