I am looking for shell commands to make the internal usb bluetooth adapter think it has been unplug and replugged in.
I know this works to fix my issue, because I have already test the theory with an external usb bluetooth device. After plugging and unplugging it my internal bluetooth loads up.
List of wireless and bluetooth drivers:
btusb 17839 1 brcm80211 775162 0 bluetooth 107148 6 rfcomm,sco,bnep,l2cap,btusb
# lsusb Bus 002 Device 003: ID 0a5c:21b4 Broadcom Corp. BCM2070 Bluetooth 2.1 + EDR
These guys are having the same issue with a wifi card after sleep, one is rebooting just one device and the other one is shooting the hole herd.
I want to find the cleanest possible option, hopefully something that only effects the targeted device.
Re: Terminal (shell) command for USB port
then you only need to do the wifi drivers.
sudo modprobe -r rt73usb rt2x00usb
sudo modprobe rt73usb rt2x00usb
you could try restarting it:
sudo ifconfig ra0 down
sudo ifconfig ra0 up
i don’t think you can do just 1 port, it’s all 1 system “usbcore”.
what device is at the end of that port that you want to restart?
anyways it’s> sudo rmmod usbcore <to remove
sudo modprobe -r usbcore
to restart it> sudo modprobe usbcore
it’s better to do the device if you can, usbcore will take out all usb’s.
i use it when i suspend, cause it won’t suspend with my usb wifi connected.
