How to bind/unbind usb device in PyUsb?

Question

I need to on/off several usb devices on my python script. Can i bind and unbind usb devices with PyUsb?

I can do it with shell commands:
Power off:
echo "device_nuber" > /sys/bus/usb/drivers/usb/unbind
Power on:
echo "device_nuber" > /sys/bus/usb/drivers/usb/bind

How execute the same in python script?

You can do this with attach_kernel_driver and detach_kernel_driver.


import usb.core
dev = usb.core.find(idVendor=0x1234,idProduct=0x5678)
# unbind interface 0
dev.detach_kernel_driver(0)
# bind interface 0
dev.attach_kernel_driver(0)

Does this behave as un/bind? I do see un/mount occurs with this code (confirmed by `lsblk` on Ubuntu) but the device remains bound/connected (confirmed by `lsusb`). – IsaacS Dec 03 '21 at 15:26
Nevermind. Confirmed this works https://stackoverflow.com/a/70311497/577001 – IsaacS Dec 10 '21 at 23:42
