Bose Sport earbuds not recognized by `bose-dfu list`

[ctag]

Hi,

This is likely operator error somewhere, but I'm hoping to document my troubleshooting in case it happens to anyone else.

I used the cargo installation method on Archlinux.

Device: Bose Sport earbuds
Model: 427929

Connected with USB-A cable (serial number edited out):

Running bose-dfu:

[berocs@bns-kharselim ~]$ sudo /home/berocs/.cargo/bin/bose-dfu list
[berocs@bns-kharselim ~]$ 

The device's idVendor looks to be correct. I expect I need to do something to the hidraw driver.

I also see the device id is the same as an incompatible product:

bose-dfu/src/device_ids.rs

Line 22 in fdf1072

bose_pid(0x40fc),

[ctag]

I know nothing about rust, but managed to get a text editor to recognize it, and learned that cargo can build locally.

The list function will return early if a device is incompatible. I removed the conflicting device ID, since my earbuds have the same one.

// Use UsbId instead of DeviceIds since some incompatible devices don't have a concept of DFU mode.
const INCOMPATIBLE_DEVICES: &[UsbId] = &[
    // Bose Noise Cancelling Headphones 700
    bose_pid(0x40ff),
    // bose_pid(0x40fc),
];

Output. I guess since these are out of warranty I don't care about hiding the serial number.

I tried using the btu.bose.com webpage from a Windows VM and capturing with wireshark, but wasn't able to make it work.

I did get the output from the webpage though:

These earbuds are stuck in the "red and white flashing LED" mode, so I know now that the btu webpage doesn't fix the issue.
