Here's how you read from USB devices in Python. It's super useful if you want to make custom drivers for certain controllers.

Can you please make a video on connecting and reading data from USB barcode scanner

[mitschcrafter]

Excuse me! i have a question. does this apply to reading HDMI input as well? because i want to make a litte thing that lets me get video feedback from nothing more then a HDMI cable, running from my computer to my gaming console. In a small window, that is emulating the behavior of a TV. i want to be able to record footage without having to pay 300 dollars for a capture card that i will only ever use once. so i thing this would be pretty handy.

hey nice video. Could you release a video for writing usb, too?

[kallan]

Thank you for this video. I would strongly implore you not to play music over voice though. It's very difficult for those with hearing difficulties.

>lsusb
'lsusb' is not recognized as an internal or external command,
operable program or batch file.

Thank you for this video!
I had some troubles and now I get a "tuple index out of range" at line 4. endpoints() seem to have no index. When I print dev it looks correct.
Does somebody have an Idea why?
Thank you (sorry I'm not very familiar with high level languages)

what module is used to access adb and to add adddevicechangeevent listener in python?

Hi, do you have video on how to read USB data from windows environment? Linux i believe does not have many security layers and easily provide access to usb, but can you please create a video on how to read data in windows using python?

[АлександрБурдин-щв]

Thanks for video. What's about getting information from pci in python?

[donato]

Excellent and clear video. I'm going to develope communication between linux running workstation (in my case Raspberry4 running Xubuntu) and laboratory measuring instrument with usb interface. Where can I find further knowledge to fulfill my goal? Thanks in advance

I’m setting the timeout to 2 while creating the serial object. When I’m reading from serial port I’m checking wether data is present in input buffer by :
if(obj.inWaiting>0) :

If the data packets are interrupted it hangs in there.... I have given timeout value as 2 still it’s waiting indefinitely... why it’s not considering timeout value????

Hi
I executed the code at 5:49 on my Windows 10 computer and it ran without errors, however I hadn't passed the parameter of "I" to is_kernel_driver_active meaning I actually disconnected the drivers from every single interface on my computer. This means I can no longer connect to WiFi even through a wired connection, I can't play audio and I can't use external peripherals like keyboard or mouse.
I'm utterly stuck with this, I know you use Linux but does anyone know how I can fix this problem?
Thank
