Hello everyone,
I'm currently going through the task 05 of the eudalypta challenge. I thought my implementation didn't work, so I tried testing a a person's solution on github. However, I am still unable to manually bind the USB device to my driver. Here are the steps I did.
1) Use lsusb -t to find the bus and port USB device was connected on. It was 1-3.

1) Use lsusb -t to find the bus and port USB device was connected on. It was 1-3.
2) Went to sys/bus/usb/devices and found that 1-3 was bound to drivers/usb using tree.
3) Used echo 1-3 > unbind to unbind it.
4) Went to devices folder and checked if it was still bound. It was not.
5) Went to the directory of my own driver, named hello_driver.
6) Tried to do echo 1-3 > bind but got the error message echo: write error: No such device.
These instructions are based on LWN.net Manual driver binding and unbinding. One suspicion I have is that this simple USB driver doesn't support the USB device I am plugging in (a USB flash drive). I actually have no idea.
Many thanks for your help.
