Unexpected interface parameters while uploading the file

[jayckc14]

Hi there,

I bought another product which is exactly the same with different PID and VID Device HID\VID_4132&PID_2107&MI_00\9&121dccff&0&0000. i converted the hex and use the command ch57x-keyboard-tool.exe --vendor-id 16690 --product-id 8455 upload < config.yaml but then it returns Error: unexpected interface parameters

Is there any fix to it? Many thanks.

Please try version 1.2.3 It won't fix your issue, but will print additional information which may be useful for troubleshooting.

Hello! I have the same problem on v1.4 - however I cant seem to figure out what the error means:

Error: unexpected interface parameters: InterfaceDescriptor {
    bLength: 9,
    bDescriptorType: 4,
    bInterfaceNumber: 0,
    bAlternateSetting: 0,
    bNumEndpoints: 1,
    bInterfaceClass: 3,
    bInterfaceSubClass: 1,
    bInterfaceProtocol: 1,
    iInterface: 0,
}

Btw: I have bought two of 3x4 with two knobs keyboards. one works, the other outputs this error. Can you help me understand?

Hello

I have the unexpected interface issue as well in v1.4. I tried v 1.2.4 and it is working i don't have the issue anymore. @ManuelMauroGiacomuzzi could you please try v 1.2.4 to check if that fixes it for you ? I have the 3 buttons 1 knob HID\VID_1189&PID_8890&REV_0000&MI_03

Thanks

Same here. Got the identical error in 1.4.0, came here to find this issue already open, tried 1.2.4 as per suggestion, and it works fine.

but on 1.2.4 it works flawlessly, my non-multimedia keyboard now has three media keys and a dedicated volume knob velcroed to it. :) Thank you for this software, that was effortless!

[ManuelMauroGiacomuzzi]

@svanhoutte yes! I can confirm it works on 1.2.4 without any problems. Another thing I noticed, is that on 1.2.4 it uploads the LAST layer while on 1.4.0 it only considers the first - just if anyone wondering why iTunes opens when clicking the first button :)

I have opened a PR with a partial fix for this in https://github.com/kriomant/ch57x-keyboard-tool/pull/69 (Note: I still need to pass --endpoint-address 2 to make my board work after my changes are applied).

[ssokolow]

I can confirm that 1.4.0 failed on a 3x4 with two knobs that was sold as non-bluetooth but 1.2.4 seems to work with the example config.

(That is, assuming it's normal for it to switch to layer 3 when programmed but then always start on layer 1 when power-cycled.)

Some for me with 3x1 1xknob no bluetooth. I get the error with 1.4.0 but works fine with 1.2.4:

Error: unexpected interface parameters: InterfaceDescriptor {
    bLength: 9,
    bDescriptorType: 4,
    bInterfaceNumber: 0,
    bAlternateSetting: 0,
    bNumEndpoints: 1,
    bInterfaceClass: 3,
    bInterfaceSubClass: 1,
    bInterfaceProtocol: 1,
    iInterface: 0,
}

I can confirm the behavior mentioned by @Bert-Tec I have a non bluetooth 2 row by 3 columns with 1 knob 1.2.4 works fine, 1.4.0 same error message
