Problem connecting to WIFI with usb WIFI adapter on debian stretch

First of all, in order to get the device to work, I installed the appropriate driver, rt2800usb, which corresponds to the chipset running on the device. After I did that, the device showed up in the Gnome network manager as "USB Wifi", which I thought was strange because in another Linux distribution I am running (Ubuntu), the device was called "Ralink WLAN..." or something like that, leading me to believe that Debian did not properly recognize the device. Regardless, when I went to connect to the wifi network, it displayed the icon showing that it was connecting for a few seconds before stopping and going back to normal without successfully connecting to the wifi access point. Sometimes it would show a "Connection Failed" dialog box.

I have tried several things to fix this. First I updated all of my packages. Then, I double checked to make sure I installed the driver properly, which I beleive I did. Here is the link: I checked the /sys/bus/usb/drivers/rt2800usb folder and the devices usb id is there, meaning the device is indeed using the rt2800usb driver. I've tried manually restarting the device with "ip link up/down" and that did nothing.

Additionally, when I ran the command "iwlist scan", the output indicates that the device "doesn't support scanning: Device or resource busy." After I ran "rfkill unblock all", the command returned results for the usb device, however I was still unable to connect to the network using the device.

I have also tried to connect to wifi that is password protected as well as open to rule out the possiblity of it being a problem with the ap.

I have no other ideas on what the problem could be...

As it turns out, I solved my problem shortly after posting here. The problem was with NetworkManager. I uninstalled it and installed wicd instead and now I am able to connect using the usb wifi device.
