usbscales issues with Satorious Practium313-1S

[seacuello]

Hello All -

I'm working with this particular scale: Satorious Practium 313-1S

I connect the scale to a raspberry pi and ran lsusb to find that it is connected and to gather the IDvendor and IDProduct values: 0x24bc & 0x0011

I then added this values to both the scales.h and rules file. I also enabled the debugging line in the make file.

I was able to make usbscales and execute it, but receive the error 'Error is USB Transport'

here is the result of running sudo ./usbscale :

pi@raspberrypi:~/Downloads/usbscale $ sudo ./usbscale Found scale 24bc:0011 (bus 1, device 6) It has descriptors: manufc: 1 prodct: 2 serial: 3 class: 239 subclass: 2 Manufacturer: Sartorius libusb: error [submit_bulk_transfer] submiturb failed error -1 errno=16 bEndpointAddress 0x85 4 0 5b 0 0 0 bEndpointAddress 0x85 4 0 0 0 0 0

here is the result of lsusb -v :

pi@raspberrypi:~/Downloads/usbscale $ lsusb -v

some additional info hope it helps:

here is my 50-usb-scales.rules file:

SUBSYSTEM=="usb", ATTR{idVendor}=="1446", ATTR{idProduct}=="6a73", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="7b7c", ATTR{idProduct}=="0100", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="2474", ATTR{idProduct}=="0550", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="2474", ATTR{idProduct}=="3550", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="0eb8", ATTR{idProduct}=="f000", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="6096", ATTR{idProduct}=="0158", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="0b67", ATTR{idProduct}=="555e", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="0922", ATTR{idProduct}=="8004", MODE="0776" SUBSYSTEM=="usb", ATTR{idVendor}=="0x24bc", ATTR{idProduct}=="0x0011", MODE="0776"

and the scales.h file:

// // scales.h // ======== // // This file is a list of all currently-recognized scales' vendor and product // IDs. // // For example, the USB product 1446:6173 becomes {0x1446, 0x6173} //

Can you read the data from it directly?

Try this simplified program: https://github.com/sanmai/usb-scale-reader/tree/master/example

[seacuello]

@sanmai - what do you mean by read directly? it does detect the new scale type if that is what you mean. I'm not too familar with php, but will take a look at what you have linked to. Thanks!

[sanmai]

There's a simple C program. Run make to build it, run it and follow directions.

If it could read weight from your device, neither this will. Otherwise there will be opportunity for PR.

@sanmai - what does PR mean? i'll work on both codes tangentially and open an issue separately.

When you plug in the scale, if it is HID (as it should be if it's standard), then you'll see a new /dev/hidraw file. Then try sudo cat /dev/hidraw4 or whatever it's called. When you put stuff on the scale it should print out gibberish (the raw data). If you can't get even this, then something is wrong.

[seacuello]

@erjiang After unpluggging all USBs and replugging the scale I found that it is hidraw0. I then tried sudo cat /dev/hidraw4 and placed items on the scale but saw no output on the terminal just seemed to stall.

[seacuello]

Here is the output I'm getting from 'sudo ./usbscale /dev/hidraw0' :

pi@raspberrypi:~/Downloads/usbscale $ sudo ./usbscale /dev/hidraw0 Found scale 24bc:0011 (bus 1, device 10) It has descriptors: manufc: 1 prodct: 2 serial: 3 class: 239 subclass: 2 Manufacturer: Sartorius libusb: error [submit_bulk_transfer] submiturb failed error -1 errno=16 bEndpointAddress 0x85 Error in USB transfer

[erjiang]

Hopefully you ran sudo cat /dev/hidraw0 as opposed to sudo cat /dev/hidraw4 as you wrote? If cat did not get you any data, then it suggests that your scale does not follow the USB HID standard for scales, and thus isn't compatible with this program.

[seacuello]

Yes I was able to get the gibberish from the scale using the sudo cat /dev/hidraw0.. Once i got that I tried to run the ./usbscale again and recieved the following:

pi@raspberrypi:~/Downloads/usbscale $ sudo ./usbscale /dev/hidraw0 Found scale 24bc:0011 (bus 1, device 16) It has descriptors: manufc: 1 prodct: 2 serial: 3 class: 239 subclass: 2 Manufacturer: Sartorius libusb: error [submit_bulk_transfer] submiturb failed error -1 errno=16 bEndpointAddress 0x85 4 0 5c 0 0 0 bEndpointAddress 0x85 4 0 0 0 0 0

[erjiang]

@seacuello If you were able to get that gibberish using cat, try recording some sample data using xxd and posting it here.

1. Run sudo cat /dev/hidraw0 | xxd | tee myoutput.txt
2. Put something on the scale and watch some data appear on-screen.
3. Ctrl-C
4. Post myoutput.txt here.

Have you checked with the scale's manufacturer to see what protocol(s) they actually support? Maybe the USB is for another purpose?

[seacuello]

@erjiang - Thanks for your help, and yes I do have a help call into the manufacturer of the scale and will share any useful info they give me.

As for sudo cat /dev/hidraw0 | xxd | tee myoutput.txt .. Here is the output not sure if it is what we were looking for :

That doesn't look like the protocol that usbscale reads. Maybe your scale has its own custom protocol?

Unfortunately there are no plans to add custom protocols to this software right now... any time spent on usbscale in the near future ideally goes towards shoring up support for the standard protocol since even that's rather incomplete.

[erjiang]

Closing issue - seems to be a non-standard scale.
