I'm added {0x04d9, 0x8010} to scales.h,

make

and run

sudo ./usbscale

and getting error

Error in USB transfer

Can you try using the Perl script found here: https://gist.github.com/erjiang/503896

It accesses the device through the kernel-provided hidraw interface and doesn't use a whitelist.

alexandr-kriptonov commented 9 years ago

I'm trying perl script and it doesn't work :(

erjiang commented 9 years ago

Hard for me to debug but it's possible that this device does not use the standard protocol or has some other problem. Sorry that I don't know more about it.

It' so bad. Your software is very attractive.
