HC-4 USB stopped working

Post by jimx »

Hi,

I just got my HC-4 today and I tested it with an sd card with the official ubuntu image (ubuntu-20.04-4.9-minimal-odroid-c4-hc4-20201212.img) installed. It booted successfully and I got to the login pretty quickly. Then I connected a USB hub with a keyboard and the wifi module 5b and it recognized the keyboard but not the wifi module (which showed up as a cdrom device). I did a full system upgrade on the ethernet and then the kernel recognized the wifi module as an NIC and I can connect to wifi with nmcli. At that point everything worked so I unplugged everything except the power cable, the sd card and the wifi module and connected to the board with ssh over wifi. Then I began to install some packages that I need and suddenly lost the connection. At first I thought it was the unstable network so I unplugged the power and rebooted the board. But the board didn't showed up on my wireless router so I connected a monitor to the board to see what was wrong. Then I began to find out the USB port didn't work as expected. Specifically, I tried to connect the board to:

1. just the keyboard. This worked normally and it can respond to my input.
2. just the wifi module. It didn't work and I can see some "device descriptor read/64, error -xx" message in dmesg.
3. a USB hub with both the keyboard and the wifi module. It didn't work either and there was not any message about USB device in dmesg as if no device was plugged in at all. The LED on the USB hub wasn't on either.

At first I suspected it was a power issue because the wifi module and the USB hub drew more power than the keyboard. But I was using the official 15V/4A power supply so there should be enough power. I didn't have any USB hub with external power supply so I wasn't sure. I could only reboot the board for several times and then the USB became completely dead. It didn't even respond to the keyboard. The only way I could connect to the board was ssh over ethernet. And there was no error/USB connected/disconnected messages showing up in dmesg. I burned the official ubuntu image to the sd card again in case there were some misconfigurations but the problem still persisted. Also, lsusb -t showed only two devices:

/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/2p, 480M

which didn't look normal at all. I remembered that when I ran lsusb to find the wifi module when the USB port did work there were more USB devices than that.

Can you please help me with this issue? Apart from the USB port everything else seems fine. I can connect to the board with ssh over ethernet and it can mount a sata disk without any problem but still I want to get the USB port to work in case I mess up with the network configuration. Thanks in advance!

Same issue, same output.

There were issues from the outset with recognising mouse / keyboard / KVM devices - garbled output from keyboard, no wireless mouse. USB storage key worked initially but shortly stopped and have tried different devices, reboots, reinstalls with both official and armbian images etc and still no luck.

Seems like could be a power issue, one of my low power usb devices lights up when plugged in to other machines, but not on HC4 usb port. This happened after about an hour or two power on, about 10mins after first plugging in usb key. It would be great if someone could tell me how to confirm if this is a software v hardware issue because the shipping cost for RMA is half the cost of the unit!

Would you guys run the commands below and capture the screen to share with me?
Please do attach any USB device - keyboard/mouse/Wifi - and sshing to HC4 to run these.

Code: Select all

uname -a
ifconfig eth0
lsusb -t
Thank you.

I do not have usb wifi, just tried keyboard, mouse, kvm and storage. Output is the same.
Currently running Armbian. Happy to put official image back on if it helps.

@jimx, For RMA, please contact your local distributor where you have purchased or send an email to odroid at hardkernel dot com if you have purchased it from Hardkernel.

@cam_l, please do share the MAC address of your HC4.

Thank you.

Not really interested in RMA. I got this direct from hardkernel and like I said the shipping cost for RMA is half the cost of the unit!

I would be interested in confirming if this is a known issue or not.

Thanks, it's an hardware issue and happened to several users AFAIK.

Just began experiencing the same issue with one of my two HC4's. Looks like the 5v pin is dead on the USB. Worked fine for a while and suddenly died. Self-powered devices work still but anything requiring power does not. MAC is 00:1e:06:49:15:2d and I bought it directly from Hardkernel. My other HC4 is fine (so far!)

I've confirmed that attaching a powered USB hub allows the USB port to work again as normal. Seems like a better option than paying for international shipping to get this RMA'd.

I just got 2 HC4's they arrived late last week and I had this issue come up on Saturday a few hours after I started using them, so it seems that this is an ongoing problem :-(

I found this thread that contains some extra info on confirming the issue for anyone interested ( viewtopic.php?t=43808 )

Argh. Looks like this issue happened to me, but it's right on the edge.

Some USB devices such as a USB 2.0 keyboard work properly. I was even able to use the HC4 to compile and flash QMK keyboard firmware to the keyboard.
Other USB devices such as two different brand new USB 3.1 flash drives don't work, BUT a third older ODROID-branded USB 3-to-SATA 3 bridge with a mechanical 7200rpm hard drive attached does work. If it were purely due to current draw, one would think the USB 3-to-SATA 3 bridge would fail, but it always works.
A USB 2.0 Realtek RTL8821C wireless adapter does work.

All of these devices are bus-powered. The two brand new USB flash drives never work on the HC4 but work perfectly when plugged into either my laptop or desktop.

I'm open to help diagnose the issue by running tests and stuff on my HC4, so long as I don't brick my device or lose the data on the two 3.5in hard drives.

No, as I don't have access to one, even at work. I'll ask around and see if I can borrow one.

I tried a third brand new USB flash drive (Sandisk 512GB).

I'm wondering if it might be that all newer USB 3.1 or 3.2 flash drives will fail, or if it might be the SCSI-over-USB (UASP) devices that fail.

My old USB 3.0 or 2.0 flash drives all work fine; it's just the brand new ones bought within the last few months that all fail.

As for trying a powered USB hub--finding one is difficult. Non-powered ones are easy to find; powered ones are rare or expensive. I wonder if the people who got it working with powered USB hubs were having the USB hub negotiate a USB 3.0 connection rather than a USB 3.1 or 3.2.

Please do share the VID and PID of yoru brand new flash drives. That could be driver issues or incompatible hardware issue somehow, FYI USB port on ODROID-HC4 is soly USB 2.0, probably it won't draw sufficient current to driver USB 3.0 storage.

Not working:

Bus 001 Device 014: ID 0781:5581 SanDisk Corp. Ultra (this is 512GB)
Bus 001 Device 015: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) Flash Drive (this is a Samsung FIT 256GB)
Bus 001 Device 020: ID 090c:2000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) USB DISK (this is a MicroCenter 128GB)
Bus 001 Device 021: ID 154b:009f PNY USB 2.0 FD
Bus 001 Device 024: ID 0781:5581 SanDisk Corp. Ultra (this is 64GB and much older than the 512GB)

Working (some are USB 3.0):

Bus 001 Device 022: ID 0781:5530 SanDisk Corp. Cruzer
Bus 001 Device 023: ID 13fe:3800 Kingston Technology Company Inc. Rage XT Flash Drive
Bus 001 Device 006: ID 152d:0578 JMicron Technology Corp. / JMicron USA Technology Corp. JMS567 SATA 6Gb/s bridge (This is the USB 3.0 to SATA 3 bridge made by HardKernel! This one was interesting because it works with one USB A SS to wide USB B cable and not with another cable.)

These are consistent (I can plug in the ones that work, and they always work, and I can plug in the ones that don't work, and they never work.) ALL of them work fine on a Windows 11 desktop PC. Most are formatted with FAT32, some with exFAT (the newest ones came with exFAT), and one (the HardKernel USB 3.0 to SATA bridge) with ext4.

Are they all connected together through HUB? Does any of them work when only one USB storage is attached?

I am always plugging them directly into the back of the HC4 for this test.
I don't own or use any USB hub at all and can't borrow a powered one.

I think my problem is slightly different than some of the others above, even though it produces the same error message.
In my case, the port works fine with some devices (including one that draws higher current) and not at all with some devices.

Update:

This might be a hardware problem with the USB port after all in my case.
I have been attempting to use dd to write a large 32GB disk image to a USB drive that normally works with the HC4.
It starts off working fine and then fails about halfway in. The USB drive is hot to the touch at the time.
I can't get the dd to complete. I can plug in the USB drive and see it, I can start the dd, but it always fails to finish.
Meanwhile, I am able to use this USB flash drive on my other computers.

I have written much more data to USB drives (500GB) on the HC4's USB port, but those were not dd command. I always used rsync or cp to transfer that data.

Perhaps this is a heat/thermal issue? Or more likely, it is indeed related to voltage or current.

Do you use a 500GB HDD with a JMS567 bridge board?
I think 1A/5V load switch(U23) on the VBUS should NOT be enough for USB HDD.
Please see a portion of the HC4 schematics.

Yes, it's a Toshiba 500GB 7200rpm 2.5in hard drive on the HardKernel ODROID-branded USB 3 to SATA 3 bridge board (not sure of chipset).

Works great every time I have tried it so far. It's not what I'm having trouble with (yet).

It seems likely that much more in-rush current might be consumed when accessing data with the dd command compared to rsync.

Probably true, if heat is any indication...
I don't have a USB voltage/current meter, but this would probably be a good use for one!

To find out the exact root cause, try using a powered USB hub like others have said.

Will do, if I can get my hands on one. I won't buy one (they're surprisingly expensive, and I don't want to buy one with the intent of using it and returning it).

No rush for now--I am using my older USB drives for now and where I need to use the newer ones, I am using an x86_64 LINUX computer instead.

You could check if U23 is getting hot during dd operation. But be careful, it may be hotter than boiling water.

This chip has more features than just a power switch. It also limits maximum current to nominal 1.3A, and when it does, it acts as a linear regulator and heats up.
It also has thermal protection that will disable the switch if its temperature goes well beyond 100C.
Both mechanisms may influence performance of the downstream drive. Limited current will mean voltage drop below specified working voltage for the drive or SATA bridge. On over-temperature event, power delivery will be completely cut.

As @odroid said, this port may not be sufficient to supply all USB drives.
If not powered USB hub, and if you know how to solder, you could build your own powered USB adapter.
All you need is a three-way USB cable. This may be impossible to buy because it doesn't conform with USB standards. But this will allow you to power USB device from a phone charger or something else, and exchange data with HC4.
This is a USB2 cable though and data rate will be limited.

You could check if U23 is getting hot during dd operation. But be careful, it may be hotter than boiling water.

This chip has more features than just a power switch. It also limits maximum current to nominal 1.3A, and when it does, it acts as a linear regulator and heats up.
It also has thermal protection that will disable the switch if its temperature goes well beyond 100C.
Both mechanisms may influence performance of the downstream drive. Limited current will mean voltage drop below specified working voltage for the drive or SATA bridge. On over-temperature event, power delivery will be completely cut.

As @odroid said, this port may not be sufficient to supply all USB drives.
If not powered USB hub, and if you know how to solder, you could build your own powered USB adapter.
All you need is a three-way USB cable. This may be impossible to buy because it doesn't conform with USB standards. But this will allow you to power USB device from a phone charger or something else, and exchange data with HC4.
This is a USB2 cable though and data rate will be limited.
Fantastic idea! Thanks mctom! I do know how to solder, and I do have lots of USB cables lying around, including USB A sockets (from USB A to A extension cables). This would be pretty easy to build. Just gotta actually go do it!

BTW, it does look like power delivery is cut when I am using dd to this specific (normally working, normally recognized) USB flash drive. It goes dark (no LED indicators at all), the /dev/sdc disappears, and the only way to get it to show up again is to unplug it and plug it back in.

It does look like overcurrent protection with foldback tripping, this is to be expected.

Another idea is to replace stock U23 chip with a variant that has 2x larger current limits. But the question is whether the upstream 5V converter will be enough. That's why I encourage you to experiment with USB cable first.
