Weird status of power relay
Closed this issue · 14 comments
I have bought a 4-way relay half an year ago and it could use with usbrelay properly at that time. However, when I took it out this morning, tried it with simple commands, it give weird output:
shihaofeng@shihaofeng-U-65LKN42:~/Downloads/usbrelay-1.0.1$ sudo usbrelay
Device Found
type: 16c0 05df
path: /dev/hidraw5
serial_number:
Manufacturer: www.dcttech.com
Product: USBRelay4
Release: 100
Interface: 0
Number of Relays = 4
�AAMZ_1=0
�AAMZ_2=0
�AAMZ_3=0
�AAMZ_4=0
shihaofeng@shihaofeng-U-65LKN42:~/Downloads/usbrelay-1.0.1$ sudo usbrelay /dev/hidraw5_0=0
*** buffer overflow detected ***: terminated
Aborted
Is it a software issue or hardware issue? Just want to confirm it. If it is a hardware one, I would just bought a new one.
Looks like the serial was corrupted. Try changing its name sudo usbrelay /dev/hidraw5_0=AAAMZ You tried to change its name to 0

Just ran a similar test on a dual relay. Note the relay serial is not invalid though.

Did you build it from the latest source from github?

no luck with the any version, I switched to use the hid interface to fix the serial name, now it is working again. Thanks anyway.
What do you mean, you switched to the hid interface? Just want the fix detailed if the same problem comes up again.

I am not sure where the problem is, all version returns buffer overflow detected, so I just use the hid_write directly, and it do fix the issue. https://github.com/libusb/hidapi/blob/bd6be4d83b36d0dcd5401fb335384586b066a2eb/linux/hid.c#L1025
Can you post the command line you used to fix it? Can you use usbrelay now?

I can use it now but its output is still weird

for the command I use to fix, I just do the similar thing you did here, so I don't know why it actually fix the issue but usbrelay built from any version cannot .
I really don't understand. This is what is supposed to happen when you use the --help option.
$ usbrelay --help
Usage: usbrelay [OPTION...] [ACTION...]
Control or query USB HID relays.
-d, --debug Produce debugging output
-e, --export-id=DEV Print relay ID of the given DEV (/dev/hidrawXX) in
udev-compatible format
-q, --quiet Be quiet
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.
Without ACTION, the actual state of all relays is printed to stdout.
ACTION can be one of:
RELID_N=[0|1] to switch the N-th relay off or on
RELID_0=NEWID to change relay ID

Have you every installed usbrelay from the debian package?
What do you get when you run:
$ sudo usbrelay -V
$ sudo usbrelay -d
looks to me like you have an ancient version installed. Probably from the debian package.
Can you run
sudo apt remove usbrelay
and rebuild and re-install it.

I think I figured out what happen, my laptop did not download from debian directly but from a local server, but that copy is old(something like 0.4). The ones is not cleaned up throughly, the newly downloaded and built one did not replace it correctly. Thanks for your time.

It works properly now. Great thanks for your patience and time!
