Unable to manually bind driver in Linux

Basically I’m trying to bind a test USB driver that is on github. It is basically just a very simple USB driver if you want to test it for yourself.

Here are the steps I did:

• Use lsusb -t to find what bus and port my usb was connected on. I found out that it was 1-3.
• Went to /sys/bus/usb/devices and found 1-3 there, and found that it was bound to drivers/usb.
• Used echo 1-3 > unbind to unbind it. I was able to successfully unbind it.
• Went to the devices folder and checked if 1-3 was still bound to anything. It was not.
• Went to the directory of my own driver, named hello_driver
• Tried to do echo 1-3 > bind but I get the error message echo: write error: No such device

Here is the output of lsusb -t if it is helpful.

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
    |__ Port 4: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/10p, 480M
    |__ Port 3: Dev 15, If 0, Class=Mass Storage, Driver=, 480M
    |__ Port 4: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
        |__ Port 3: Dev 5, If 1, Class=Human Interface Device, Driver=usbhid, 1.5M
        |__ Port 3: Dev 5, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
        |__ Port 2: Dev 4, If 0, Class=Human Interface Device, Driver=usbhid, 12M
        |__ Port 2: Dev 4, If 1, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 10: Dev 3, If 0, Class=Wireless, Driver=btusb, 12M
    |__ Port 10: Dev 3, If 1, Class=Wireless, Driver=btusb, 12M

I’m not sure what the problem is. I know other people have asked this but their solutions didn’t help in my case. It seems as if this error only appears in my own driver, but not others. Thanks.
