QUESTION
I want to control an 8K monitor with pyusb. I know the c++ api functions from their documentation. But they don't supply the values to send for those commands. Is there a way to find what values or messages correspond to the functions to send with a libusb control transfer? E.g. getting and setting brightness, and connecting and disconnecting the monitor, on a Linux machine (Ubuntu server, while the API only supports versions of Fedora and CentOS).

...ANSWER
Answered 2022-Feb-18 at 04:43There is no standard procedure to figure out vendor-specific USB commands, because they are defined by the vendor. If you can get the device software running and working on your computer, then you can use a USB traffic sniffer like WireShark or a Beagle to look at the traffic it generates and reverse engineer how it works.

QUESTION
I'm implementing USB web cam on top of Atmega32U4.
I think I managed to implement transactions on the control endpoint, more or less correctly, as all the descriptors are transited and device reports correctly in the system.
Issue is when I'm trying to send video data out of the device, as nothing seems to go through.
The way I implemented data transmission (according to section 22.14 of datasheet) is as follows:
...ANSWER
Answered 2021-Dec-30 at 16:58The reason why uvc driver is not pulling any data for the device, is that you set dwMaxVideoFrameSize
and dwMaxPayloadTransferSize
to 0
. Set it to value high enough for your case and it will work.

Answered 2021-Dec-27 at 17:01After trying for a few days and just found out that pip and python in the project are not pointing to .venv but to anaconda due to an update. when error
no module stdnum
actually there is a problem with pip so make sure your pip path with which pip or which python
- to solve .venv that doesn't work by deleting the .venv folder, create venv in python, and install all requirements again

QUESTION
I have a USB device for which the following code
...ANSWER
Answered 2021-Dec-16 at 10:03To write into endpoint 0, you'll need the device.ctrl_transfer(bmRequestType, bmRequest, wValue, wIndex, packet)
instead of endpoint.write(packet)
.
The bmRequestType
, bmRequest
, wValue
and wIndex
correspond to the same elements in the USB control request. The fact that the Windows software uses hidapi
suggests the control transfers are done according to the USB HID specification.
This answer here on Stack Overflow describes how to make USB HID set/get operations on plain PyUSB.
But since the source code you're porting uses hidapi
, using the Python hidapi interface might make the process more straightforward. This question has an example of using hidapi
in Python, and the answers also talk about alternatives.

QUESTION
Is there a way with pyusb to unbind a USB device?
I know using the following bash
the USB is unbound.
ANSWER
Answered 2021-Dec-03 at 19:31A quick search of the PyUSB code makes it seem like there is no feature for binding or unbinding. So PyUSB is not the answer.
However, you don't need to use Bash to unbind a device. Python has a standard library that lets you get directory listings, read files, and write to files, so you can just use Python's standard library instead of Bash.

Install pyusb
You can use pyusb like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
