There is absolutely nothing wrong here.
You enabled PYUSB_DEBUG, and called usb.core.find().
The default is for find() to find (at most) a single USB device, which,
according to the debug output, it did (even though it appears that you
omitted the IDLE output that looks something like `<DEVICE ID ffff:ffff
on Bus 001 Address 001>`).
Maybe you wanted to store the device returned by find() somewhere?
Also, generally speaking, you either want to find one of a specific device
usb.core.find(idVendor=<...>, idProduct=<...>)
or all devices (optionally also filtering by idVendor and/or idProduct)
usb.core.find(find_all=True)
usb.core.find(find_all=True, idVendor=<...>)
usb.core.find(find_all=True, idVendor=<...>, idProduct=<...>)
but rarely do you need a single randomly picked device.
My suggestion is for you to (continue to) follow the PyUSB tutorial:
https://github.com/pyusb/pyusb/blob/master/docs/tutorial.rst
Thanks,
Jonas

thanks for the previous answer. I also get the error.
When I applied the following few lines in IDLE Python GUI:
import usb.core
dev = usb.core.find(idVendor=0x10c4, idProduct=0xea61)
ep = dev[0].interfaces()[0].endpoints()[0]
i = dev[0].interfaces()[0].bInterfaceNumber
dev.reset()
if dev.is_kernel_driver_active(i):
dev.datach_kernel_driver(i)
dev.set_configuration()
eaddr = ep.bEndpointAddress
r = dev.read(eaddr, 1024)
print(r)
I have got the following response :
Traceback (most recent call last):

That said, don't replace the driver if you don't need to; you could unintentionally block access to the device from other programs, as well as invite problems from potential corner cases.
