Not working with "Bluetooth Mini-Receiver"

[robclancy]

Do you provide help with stuff like this? I don't want to waste time writing a lot of stuff out if you don't have the time to help anyway.

Basically I added the new product code and it selected the device but it doesn't work.

Here is the device from lsusb -v.

And then there are 2 more devices in there but neither can be selected with the ioctl by adding the product code. Only the one above gets detected there.

Hi, I'm not the original author of this tool, but maybe I can help. When you say it doesn't work, what kind of error do you encounter?

[robclancy]

There are no errors unless I try check battery in which case it says bad answer:01 8F 81 0D 08 00.

Is there somewhere else I should ask for help or is this a lost cause? It isn't super important for me.

[asl97]

maybe this is fix in tech2077 fork by tech2077@5a95b22 .

his fork has plenty of warning message though, i fixed those in my fork and currently waiting for him to respond to a pull request.
