I'm using adafruit's usb to ttl gadget to communicate with my raspberry pi over usb. For some reason when I plug in my Raspberry Pi Ralink RT8188 wifi dongle and reboot, I can't access my raspberry pi over usb anymore. I use screen like this to access my raspberry pi:
screen /dev/ttyUSB0 115200
Any reason why I can't access my raspberry pi over usb when I am using a wifi dongle?
EDIT: dmesg output before WiFi.
lsusb before WiFi:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub.
dmesg output after WiFi.
lsusb after WiFi:
Bus 001 Device 003: ID 148f:7601 Ralink Technology, Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
It seems like it kindof works when having the wifi dongle, except the output is totally broken (logged in and ran command
